Khmer

Khmer has been influenced considerably bySanskritandPaliespecially in the royal and religiousregisters,throughHinduism and Buddhism,due toOld Khmerbeing the language of the historical empires ofChenla,Angkor.

The vast majority of Khmer speakers speakCentral Khmer,the dialect of the central plain where the Khmer are most heavily concentrated. Within Cambodia, regional accents exist in remote areas but these are regarded as varieties of Central Khmer. Two exceptions are the speech of the capital,Phnom Penh,and that of theKhmer KheinStung Treng province,both of which differ sufficiently enough from Central Khmer to be considered separate dialects of Khmer.

Outside of Cambodia, three distinct dialects are spoken by ethnic Khmers native to areas that were historically part of theKhmer Empire.TheNorthern Khmer dialectis spoken by over a million Khmers in the southern regions ofNortheast Thailandand is treated by some linguists as a separate language. Khmer Krom, or Southern Khmer, is the first language of theKhmer of Vietnam,while the Khmer living in the remoteCardamom Mountainsspeak a very conservative dialect that still displays features of theMiddle Khmerlanguage.

Khmer is primarily ananalytic,isolating language.There are noinflections,conjugationsorcaseendings. Instead,particlesand auxiliary words are used to indicate grammatical relationships. General word order issubject–verb–object,andmodifiersfollow the word they modify.Classifiersappear after numbers when used to count nouns, though not always so consistently as in languages likeChinese.In spoken Khmer,topic-commentstructure is common, and the perceived social relation between participants determines which sets of vocabulary, such as pronouns and honorifics, are proper.

Khmer differs from neighboring languages such asBurmese,Thai,Lao,andVietnamesein that it is not atonal language.Words arestressedon the final syllable, hence many words conform to the typical Mon–Khmer pattern of a stressed syllable preceded by aminor syllable.The language has been written in theKhmer script,anabugidadescended from theBrahmi scriptvia the southern IndianPallava script,since at least the 7th century. The script's form and use has evolved over the centuries; its modern features include subscripted versions of consonants used to writeclustersand a division of consonants into two series with differentinherent vowels.

Classification

Main article:Austroasiatic languages

Khmer is a member of theAustroasiaticlanguage family, the autochthonous family in an area that stretches from the Malay Peninsula through Southeast Asia to East India.Austroasiatic, which also includesMon,VietnameseandMunda,has been studied since 1856 and was first proposed as a language family in 1907.Despite the amount of research, there is still doubt about the internal relationship of the languages of Austroasiatic.

Diffloth places Khmer in an eastern branch of theMon-Khmer languages.In these classification schemes Khmer's closest genetic relatives are theBahnaricandPearic languages.More recent classifications doubt the validity of the Mon-Khmer sub-grouping and place the Khmer language as its own branch of Austroasiatic equidistant from the other 12 branches of the family.

Geographic distribution and dialects

The approximate locations where various dialects of Khmer are spoken

Khmer is spoken by some 13 million people inCambodia,where it is the official language. It is also a second language for most of the minority groups and indigenous hill tribes there. Additionally there are a million speakers of Khmer native to southernVietnam(1999 census)and 1.4 million in northeastThailand(2006).

Khmerdialects,although mutually intelligible, are sometimes quite marked. Notable variations are found in speakers fromPhnom Penh(Cambodia's capital city), the ruralBattambangarea, the areas of Northeast Thailand adjacent to Cambodia such asSurin province,theCardamom Mountains,and southern Vietnam.The dialects form acontinuumrunning roughly north to south. Standard Cambodian Khmer is mutually intelligible with the others but aKhmer Kromspeaker from Vietnam, for instance, may have great difficulty communicating with a Khmer native ofSisaket Provincein Thailand.

The following is a classification scheme showing the development of the modern Khmer dialects.

• Middle Khmer
  • Cardamom (Western) Khmer
  • Central Khmer
    • Surin (Northern) Khmer
    • Standard Khmer and related dialects (including Khmer Krom)

A speaker of the Phnom Penh dialect of Khmer.

Standard Khmer,orCentral Khmer,the language as taught in Cambodian schools and used by the media, is based on the dialect spoken throughout theCentral Plain,a region encompassed by the northwest and central provinces.

Northern Khmer(calledKhmer Surinin Khmer) refers to the dialects spoken by many in several border provinces of present-day northeast Thailand. After the fall of the Khmer Empire in the early 15th century, the Dongrek Mountains served as a natural border leaving the Khmer north of the mountains under the sphere of influence of the Kingdom ofLan Xang.The conquests of Cambodia byNaresuanthe Great forAyutthayafurthered their political and economic isolation from Cambodia proper, leading to a dialect that developed relatively independently from the midpoint of the Middle Khmer period.

This has resulted in a distinct accent influenced by the surrounding tonal languagesLaoandThai,lexical differences, and phonemic differences in both vowels and distribution of consonants. Syllable-final/r/,which has become silent in other dialects of Khmer, is still pronounced in Northern Khmer. Some linguists classify Northern Khmer as a separate but closely related language rather than a dialect.

Western Khmer,also called Cardamom Khmer or Chanthaburi Khmer, is spoken by a very small, isolated population in theCardamom mountainrange extending from western Cambodia into easternCentral Thailand.Although little studied, this variety is unique in that it maintains a definite system ofvocal registerthat has all but disappeared in other dialects of modern Khmer.

Phnom Penh Khmeris spoken in the capital and surrounding areas. This dialect is characterized by merging or completeelisionof syllables, which speakers from other regions consider a "relaxed" pronunciation. For instance, "Phnom Penh" is sometimes shortened to "m'Penh". Another characteristic of Phnom Penh speech is observed in words with an "r" either as an initial consonant or as the second member of aconsonant cluster(as in the English word "bread" ). The "r",trilledorflappedin other dialects, is either pronounced as auvular trillor not pronounced at all.

This alters the quality of any preceding consonant, causing a harder, more emphasized pronunciation. Another unique result is that the syllable is spoken with a low-rising or "dipping"tonemuch like the "hỏi" tone inVietnamese.For example, some people pronounceត្រី[trəj]('fish') as[tʰəj]:the[r]is dropped and the vowel begins by dipping much lower in tone than standard speech and then rises, effectively doubling its length. Another example is the wordរៀន[riən]('study'), which is pronounced[ʀiən],with the uvular "r" and the same intonation described above.

Khmer KromorSouthern Khmeris spoken by the indigenous Khmer population of theMekong Delta,formerly controlled by the Khmer Empire but part of Vietnam since 1698. Khmers are persecuted by the Vietnamese government for using their native language and, since the 1950s, have been forced to take Vietnamese names.Consequently, very little research has been published regarding this dialect. It has been generally influenced by Vietnamese for three centuries and accordingly displays a pronounced accent, tendency toward monosyllabic words and lexical differences from Standard Khmer.

Khmer Kheis spoken in theSe San,SrepokandSekongriver valleys ofSesanandSiem Pangdistricts inStung Treng Province.Following the decline of Angkor, the Khmer abandoned their northern territories, which the Lao then settled. In the 17th century, Chey Chetha XI led a Khmer force into Stung Treng to retake the area. The Khmer Khe living in this area of Stung Treng in modern times are presumed to be the descendants of this group. Their dialect is thought to resemble that of pre-modern Siem Reap.

Historical periods

A stone carved in Old Khmer

Linguisticstudy of the Khmer language divides its history into four periods one of which, the Old Khmer period, is subdivided into pre-Angkorian and Angkorian.Pre-Angkorian Khmer is the Old Khmer language from 600 CE through 800. Angkorian Khmer is the language as it was spoken in theKhmer Empirefrom the 9th century until the 13th century.

The following centuries saw changes inmorphology,phonologyandlexicon.The language of this transition period, from about the 14th to 18th centuries, is referred to as Middle Khmer and saw borrowings from Thai in the literary register.Modern Khmer is dated from the 19th century to today.

The following table shows the conventionally accepted historical stages of Khmer.

Historical Stages of Khmer

Historical stage	Date
Pre- orProto-Khmer	Before 600 CE
Pre-Angkorian Old Khmer	600–800
Angkorian Old Khmer	800 to mid-14th century
Middle Khmer	Mid-14th century to 18th century
Modern Khmer	1800–present

Just as modern Khmer was emerging from the transitional period represented by Middle Khmer, Cambodia fell under theinfluenceofFrenchcolonialism.Thailand, which had for centuries claimed suzerainty over Cambodia and controlled succession to the Cambodian throne, began losing its influence on the language.In 1887 Cambodia was fully integrated intoFrench Indochina,which brought in aFrench-speaking aristocracy. This led to French becoming the language of higher education and the intellectual class. By 1907, the French had wrested over half of modern-day Cambodia, including the north and northwest where Thai had been the prestige language, back from Thai control and reintegrated it into the country.

Many native scholars in the early 20th century, led by a monk namedChuon Nath,resisted the French and Thai influences on their language. Forming the government sponsored Cultural Committee to define and standardize the modern language, they championed Khmerization, purging of foreign elements, reviving affixation, and the use of Old Khmer roots and historical Pali and Sanskrit to coin new words for modern ideas.Opponents, led byKeng Vannsak,who embraced "total Khmerization" by denouncing the reversion to classical languages and favoring the use of contemporary colloquial Khmer for neologisms, andIeu Koeus,who favored borrowing from Thai, were also influential.

Koeus later joined the Cultural Committee and supported Nath. Nath's views and prolific work won out and he is credited with cultivating modern Khmer-language identity and culture, overseeing the translation of the entire Pali Buddhist canon into Khmer. He also created the modern Khmer language dictionary that is still in use today, helping preserve Khmer during the French colonial period.

Phonology

The phonological system described here is the inventory of sounds of the standard spoken language,represented using theInternational Phonetic Alphabet(IPA).

Consonants

		Labial	Alveolar	Palatal	Velar	Glottal
Nasal		m ម, ម៉	n ន, ណ	ɲ ញ, ញ៉	ŋ ង, ង៉
Plosive	voiceless	p(pʰ) ផ​, ភ, ព	t(tʰ) ថ, ឋ, ឍ, ធ	c(cʰ) ឆ, ឈ	k(kʰ) ក, គ, ខ, ឃ	ʔ អ, អ៊
	voiced	ɓ~b ប, ប៊	ɗ~d ដ, ឌ
Fricative			s ស, ស៊	(ç) ច, ជ		h ហ, ហ៊
Liquid	rhotic		r រ៉, រ
	lateral		l ឡ, ល
Approximant		ʋ~w វ៉, វ		j យ៉, យ

The voiceless plosives/p/,/t/,/c/,/k/may occur with or withoutaspiration(as[p]vs.[pʰ],etc.); this difference is contrastive before a vowel. However, the aspirated sounds in that position may be analyzed as sequences of twophonemes:/ph/,/th/,/ch/,/kh/.This analysis is supported by the fact thatinfixescan be inserted between the stop and the aspiration; for example[tʰom]('big') becomes[tumhum]('size') with a nominalizing infix. When one of these plosives occurs initially before another consonant, aspiration is no longer contrastive and can be regarded as mere phonetic detail:slight aspiration is expected when the following consonant is not one of/ʔ/,/b/,/d/,/r/,/s/,/h/(or/ŋ/if the initial plosive is/k/).

The voiced plosives are pronounced asimplosives[ɓ,ɗ]by most speakers, but this feature is weak in educated speech, where they become[b,d].

In syllable-final position,/h/and/ʋ/approach[ç]and[w]respectively. The stops/p/,/t/,/c/,/k/are unaspirated and haveno audible releasewhen occurring as syllable finals.

In addition, the consonants/ɡ/,/f/,/ʃ/and/z/occur occasionally in recentloan wordsin the speech of Cambodians familiar with French and other languages.

Vowels

Various authors have proposed slightly different analyses of the Khmer vowel system. This may be in part because of the wide degree of variation in pronunciation between individual speakers, even within a dialectal region.The description below follows Huffman (1970).The number of vowel nuclei and their values vary between dialects; differences exist even between the Standard Khmer system and that of the Battambang dialect on which the standard is based.

In addition, some diphthongs and triphthongs are analyzed as a vowel nucleus plus asemivowel(/j/or/w/) coda because they cannot be followed by a final consonant. These include: (with short monophthongs)/ɨw/,/əw/,/aj/,/aw/,/uj/;(with long monophthongs)/əːj/,/aːj/;(with long diphthongs)/iəj/,/iəw/,/ɨəj/,/aoj/,/aəj/and/uəj/.

The Independent vowels are the vowels that can exist without a preceding or trailing consonant. The independent vowels may be used as monosyllabic words, or as the initial syllables in longer words. Khmer words never begin with regular vowels; they can, however, begin with independent vowels. Example: ឰដ៏, ឧទាហរណ៍, ឧត្តម, ឱកាស...។

Syllable structure

A Khmersyllablebegins with a single consonant, or else with aclusterof two, or rarely three, consonants. The only possible clusters of three consonants at the start of a syllable are/str/,/skr/,and (with aspirated consonants analyzed as two-consonant sequences)/sth/,/lkh/.There are 85 possible two-consonant clusters (including [pʰ] etc. analyzed as/ph/etc.). All the clusters are shown in the following table, phonetically, i.e. superscriptʰcan mark either contrastive or non-contrastive aspiration (seeabove).

l	lp-	lɓ-				lk-	lʔ-	lm-			lŋ-					lh-	lʋ-		lkʰ-

Slight vowelepenthesisoccurs in the clusters consisting of a plosive followed by/ʔ/,/b/,/d/,in those beginning/ʔ/,/m/,/l/,and in the cluster/kŋ-/.

After the initial consonant or consonant cluster comes the syllabicnucleus,which is one of thevowelslisted above. This vowel may end the syllable or may be followed by acoda,which is a single consonant. If the syllable is stressed and the vowel is short, there must be a final consonant. All consonant sounds except/b/,/d/,/r/,/s/and the aspirates can appear as the coda (although final/r/is heard in some dialects, most notably inNorthern Khmer).

Aminor syllable(unstressed syllable preceding the main syllable of a word) has a structure of CV-, CrV-, CVN- or CrVN- (where C is a consonant, V a vowel, and N a nasal consonant). The vowels in such syllables are usually short; in conversation they may bereducedto[ə],although in careful or formal speech, including on television and radio, they are clearly articulated. An example of such a word isមនុស្សmɔnuh, mɔnɨh, mĕəʾnuh('person'), pronounced[mɔˈnuh],or more casually[məˈnuh].

Stress

Stressin Khmer falls on the final syllable of a word.Because of this predictable pattern, stress is non-phonemicin Khmer (it does not distinguish different meanings).

Most Khmer words consist of either one or two syllables. In most native disyllabic words, the first syllable is aminor(fully unstressed) syllable. Such words have been described assesquisyllabic(i.e. as having one-and-a-half syllables). There are also some disyllabic words in which the first syllable does not behave as a minor syllable, but takessecondary stress.Most such words arecompounds,but some are singlemorphemes(generally loanwords). An example isភាសា('language'), pronounced[ˌpʰiəˈsaː].

Words with three or more syllables, if they are not compounds, are mostly loanwords, usually derived from Pali, Sanskrit, or more recently, French. They are nonetheless adapted to Khmer stress patterns.Primary stress falls on the final syllable, withsecondary stresson every second syllable from the end. Thus in a three-syllable word, the first syllable has secondary stress; in a four-syllable word, the second syllable has secondary stress; in a five-syllable word, the first and third syllables have secondary stress, and so on.Long polysyllables are not often used in conversation.

Compounds, however, preserve the stress patterns of the constituent words. Thusសំបុកចាប,the name of a kind of cookie (literally 'bird's nest'), is pronounced[sɑmˌbokˈcaːp],with secondary stress on the second rather than the first syllable, because it is composed of the words[sɑmˈbok]('nest') and[caːp]('bird').

Phonation and tone

See also:Tonogenesis

Khmer once had aphonationdistinction in its vowels, but this now survives only in the most archaic dialect (Western Khmer).The distinction arose historically when vowels after Old Khmer voiced consonants becamebreathy voicedand diphthongized; for example*kaa,*ɡaabecame*kaa,*ɡe̤a.When consonant voicing was lost, the distinction was maintained by the vowel (*kaa,*ke̤a); later the phonation disappeared as well ([kaː],[kiə]).These processes explain the origin of what are now called a-series and o-series consonants in theKhmer script.

Although most Cambodian dialects are nottonal,the colloquial Phnom Penh dialect has developed a tonal contrast (level versus peaking tone) as a by-product of theelisionof/r/.

Intonation

Intonationoften conveyssemanticcontext in Khmer, as in distinguishingdeclarative statements,questions and exclamations. The available grammatical means of making such distinctions are not always used, or may be ambiguous; for example, the finalinterrogative particleទេ/teː/can also serve as an emphasizing (or in some cases negating) particle.

The intonation pattern of a typical Khmer declarative phrase is a steady rise throughout followed by an abrupt drop on the last syllable.

ខ្ញុំមិនចង់បានទេ[↗kʰɲommɨncɑŋbaːn|↘teː]('I don't want it')

Other intonation contours signify a different type of phrase such as the "full doubt" interrogative, similar toyes–no questionsin English. Full doubt interrogatives remain fairly even in tone throughout, but rise sharply towards the end.

អ្នកចង់ទៅលេងសៀមរាបទេ[↗neaʔcaŋ|↗tɨwleːŋsiəmriəp|ꜛteː]('do you want to go to Siem Reap?')

Exclamatory phrases follow the typical steadily rising pattern, but rise sharply on the last syllable instead of falling.

សៀវភៅនេះថ្លៃណាស់[↗siəwpʰɨwnih|↗tʰlaj|ꜛnah]('this book is expensive!')

Grammar

Main article:Khmer grammar

Khmer is primarily ananalytic languagewith noinflection.Syntactic relations are mainly determined by word order. Old andMiddle Khmerused particles to markgrammatical categoriesand many of these have survived in Modern Khmer but are used sparingly, mostly in literary or formal language.Khmer makes extensive use ofauxiliary verbs,"directionals" andserial verb construction.Colloquial Khmer is azero copulalanguage, instead preferring predicative adjectives (and even predicative nouns) unless using a copula for emphasis or to avoid ambiguity in more complex sentences. Basic word order issubject–verb–object(SVO), although subjects are oftendropped;prepositionsare used rather than postpositions.

Topic-Commentconstructions are common and the language is generallyhead-initial(modifiers follow the words they modify). Some grammatical processes are still not fully understood by western scholars. For example, it is not clear if certain features of Khmer grammar, such asactor nominalization,should be treated as a morphological process or a purely syntactic device,and some derivational morphology seems "purely decorative" and performs no known syntactic work.

Lexical categorieshave been hard to define in Khmer.Henri Maspero,an early scholar of Khmer, claimed the language had no parts of speech,while a later scholar, Judith Jacob, posited four parts of speech and innumerable particles.John Haiman,on the other hand, identifies "a couple dozen" parts of speech in Khmer with the caveat that Khmer words have the freedom to perform a variety of syntactic functions depending on such factors as word order, relevant particles, location within a clause, intonation and context.Some of the more important lexical categories and their function are demonstrated in the following example sentence taken from a hospital brochure:

Morphology

Modern Khmer is anisolating language,which means that it uses littleproductivemorphology.There is somederivationby means ofprefixesandinfixes,but this is a remnant of Old Khmer and not always productive in the modern language.Khmer morphology is evidence of a historical process through which the language was, at some point in the past, changed from being anagglutinative languageto adopting an isolating typology.Affixed forms arelexicalizedand cannot be used productively to form new words.Below are some of the most common affixes with examples as given by Huffman.

Affix	Function	Word	Meaning	Affixed Word	Meaning
prefixed[pʰ]	causation	[ɗac] [ɗaəm]	"broke, torn" "origin"	[pʰɗac] [pʰɗaəm]	"to tear apart" "to originate (trans.)"

Compoundingin Khmer is a common derivational process that takes two forms, coordinate compounds and repetitive compounds. Coordinate compounds join twounbound morphemes(independent words) of similar meaning to form a compound signifying a concept more general than either word alone.Coordinate compounds join either two nouns or two verbs. Repetitive compounds, one of the most productive derivational features of Khmer, usereduplicationof an entire word to derive words whose meaning depends on the class of the reduplicated word.A repetitive compound of a noun indicates plurality or generality while that of an adjectival verb could mean either an intensification or plurality.

Coordinate compounds:

[ʔəwpuk]

father

+

[mɗaːj]

mother

⇒

[ʔəwpuk.mɗaːj]

parents

[ʔəwpuk] + [mɗaːj] ⇒ [ʔəwpuk.mɗaːj]

[nɔəm]

to bring

⇒

[ɗəknŏəm]

[ɗək] + [nɔəm] ⇒ [ɗəknŏəm]

{to transport} {} {to bring} {} {to lead}

Repetitive compounds:

[cʰap]

fast

⇒

[cʰapcʰap]

very fast, quickly

[cʰap] ⇒ [cʰapcʰap]

fast {} {very fast, quickly}

[srəj]

women

⇒

[srəjsrəj]

women, women in general

[srəj] ⇒ [srəjsrəj]

women {} {women, women in general}

Nouns and pronouns

Khmernounsdo not inflect forgrammatical genderorsingular/plural.There are noarticles,but indefiniteness is often expressed by the word for "one" (មួយ[muəj]) following the noun as inឆ្កែមួយ([cʰkaemuəj]"a dog" ). Plurality can be marked bypostnominalparticles, numerals, or reduplication of a following adjective, which, although similar to intensification, is usually not ambiguous due to context.

[cʰkae

dog

craən]

many

[cʰkae craən]

dog many

"many dogs"

[cʰkae

dog

piː]

two

[cʰkae piː]

dog two

"two dogs"

[cʰkae

dog

tʰom

large

tʰom]

large

[cʰkae tʰom tʰom]

dog large large

'large dogs'

Classifying particlesare used after numerals, but are not always obligatory as they are inThaiorChinese,for example, and are often dropped in colloquial speech. Khmer nouns are divided into two groups: mass nouns, which take classifiers; and specific, nouns, which do not. The overwhelming majority are mass nouns.

"two pencils"

Possession is colloquially expressed by word order. The possessor is placed after the thing that is possessed.Alternatively, in more complex sentences or when emphasis is required, a possessive construction using the wordរបស់([rɔːbɑh]~[lə.bɑh],"property, object" ) may be employed. In formal and literary contexts, the possessive particleនៃ([nɨj]) is used:

[puəʔmaːʔ

friend

kʰɲom]

I

[puəʔmaːʔ kʰɲom]

friend I

"my friend"

[puəʔmaːʔ

friend

rɔːɓɑh

property

kʰɲom]

I

[puəʔmaːʔ rɔːɓɑh kʰɲom]

friend property I

"my friend"

[puəʔmaːʔ

friend

nɨj

of

kʰɲom]

I

[puəʔmaːʔ nɨj kʰɲom]

friend of I

"my friend"

Pronounsare subject to a complicated system of social register, the choice of pronoun depending on the perceived relationships between speaker, audience and referent (seeSocial registersbelow). Khmer exhibitspronoun avoidance,so kinship terms, nicknames and proper names are often used instead of pronouns (including for the first person) among intimates. Subject pronouns are frequentlydroppedin colloquial conversation.

Adjectives, verbs and verb phrases may be made into nouns by the use ofnominalizationparticles. Three of the more common particles used to create nouns are[kaː],[seckdəj],and[pʰiəp].These particles are prefixed most often to verbs to form abstract nouns. The latter, derived from Sanskrit, also occurs as a suffix in fixed forms borrowed from Sanskrit and Pali such as[sokʰapʰiəp]( "health" ) from[sok]( "to be healthy" ).

Adjectives and adverbs

Adjectives,demonstrativesandnumeralsfollow the noun they modify. Adverbs likewise follow the verb. Morphologically, adjectives and adverbs are not distinguished, with many words often serving either function. Adjectives are also employed as verbs as Khmer sentences rarely use acopula.

Degrees of comparisonare constructed syntactically.Comparativesare expressed using the wordជាង/ciəŋ/:"A X/ciəŋ/[B] "(A is more X [than B]). The most common way to expresssuperlativesis withជាងគេ/ciəŋkeː/:"A X/ciəŋkeː/"(A is the most X).Intensity is also expressed syntactically, similar to other languages of the region, byreduplicationor with the use ofintensifiers.

Verbs

As is typical of most East Asian languages,Khmer verbs do not inflect at all;tense,aspectandmoodcan be expressed using auxiliary verbs, particles (such asកំពុង/kəmpuŋ/,placed before a verb to expresscontinuous aspect) and adverbs (such as "yesterday", "earlier", "tomorrow" ), or may be understood from context.Serial verb constructionis quite common.

Khmer verbs are a relativelyopen classand can be divided into two types, main verbs and auxiliary verbs.Huffman defined a Khmer verb as "any word that can be (negated)",and further divided main verbs into three classes.

Transitive verbsare verbs that may be followed by adirect object:

/kʰɲom

I

ɲam

eat

ɓaj/

rice

/kʰɲom ɲam ɓaj/

I eat rice

"I eat rice."

/kʰɲom

I

tɨɲ

buy

ɓaːrəj/

cigarettes

/kʰɲom tɨɲ ɓaːrəj/

I buy cigarettes

"I buy cigarettes."

Intransitive verbsare verbs that can not be followed by an object:

/kʰɲom

I

ɗaə

walk

tɨw

DIR

pʰsaː/

market

/kʰɲom ɗaə tɨw pʰsaː/

I walk DIR market

"I walk to the market."

/ʔaɲcəɲ

to invite

ʔɑŋkuj/

to sit

/ʔaɲcəɲ ʔɑŋkuj/

{to invite} {to sit}

"Please sit."

Adjectival verbs are a word class that has no equivalent in English. When modifying a noun or verb, they function as adjectives or adverbs, respectively, but they may also be used as main verbs equivalent to English "be +adjective".

Adjective:

/proh

boy

sɑŋ.haː/

handsome

/prohsɑŋ.haː/

"handsome boy"

Adverb:

Syntax

Syntaxis the rules and processes that describe how sentences are formed in a particular language, how words relate to each other within clauses or phrases and how those phrases relate to each other within a sentence to convey meaning.Khmer syntax is veryanalytic.Relationships between words and phrases are signified primarily by word order supplemented with auxiliary verbs and, particularly in formal and literary registers, grammatical marking particles.Grammatical phenomena such asnegationandaspectare marked by particles whileinterrogativesentences are marked either by particles orinterrogative wordsequivalent to English "wh-words".

A complete Khmer sentence consists of four basic elements—an optional topic, an optional subject, an obligatory predicate, and various adverbials and particles.The topic and subject arenoun phrases,predicates areverb phrasesand another noun phrase acting as anobjector verbal attribute often follows the predicate.

Basic constituent order

When combining these noun and verb phrases into a sentence the order is typically SVO:

/kʰɲom

I

SBJ

ʔaoj

give

VERB

ceik

banana

OBJ

muəj

one

cɑmnuən/

bunch[CLF]

/kʰɲom ʔaoj ceik muəj cɑmnuən/

I give banana one bunch[CLF]

SBJ VERB OBJ {} {}

'I gave a bunch of bananas.'

When both adirect objectandindirect objectare present without any grammatical markers, the preferred order is SV(DO)(IO). In such a case, if the direct object phrase contains multiple components, the indirect object immediately follows the noun of the direct object phrase and the direct object's modifiers follow the indirect object:

/kʰɲom

I

SBJ

ʔaoj

give

VERB

ceik

banana

DO

cruːk

pig

IO

muəj

one

cɑmnuən/

bunch[CLF]

/kʰɲom ʔaoj ceik cruːk muəj cɑmnuən/

I give banana pig one bunch[CLF]

SBJ VERB DO IO {} {}

'I gave the pig a bunch of bananas.'

This ordering of objects can be changed and the meaning clarified with the inclusion of particles. The word/dɑl/,which normally means "to arrive" or "towards", can be used as a preposition meaning "to":

/kʰɲom

I

ʔaoj

give

ceik

banana

muəj

one

cɑmnuən

bunch[CLF]

dɑl

toward

cruːk/

pig

/kʰɲom ʔaoj ceik muəj cɑmnuən dɑl cruːk/

I give banana one bunch[CLF] toward pig

'I gave a bunch of bananas to the pigs.'

Alternatively, the indirect object could precede the direct object if the object-marking preposition/nəw/were used:

/kʰɲom

I

ʔaoj

give

cruːk

pig

nəw

OM

ceik

banana

muəj

one

cɑmnuən/

bunch[CLF]

/kʰɲom ʔaoj cruːk nəw ceik muəj cɑmnuən/

I give pig OM banana one bunch[CLF]

'I gave the pig a bunch of bananas.'

However, in spoken discourse OSV is possible when emphasizing the object in atopic–comment-like structure.

/tuːk

boat

muəj

one

kɔŋ

to sit

pram

five

ʔɑŋ/

monk[CLF]

/tuːk muəj kɔŋ pram ʔɑŋ/

boat one {to sit} five monk[CLF]

'In a boat sit five monks.'

/ʋɪʔciə

science

cao

thief

luəc

to steal

mɨn

NEG

baːn/

COMPL

/ʋɪʔciə cao luəc mɨn baːn/

science thief {to steal} NEG COMPL

'Science, a thief can not steal.'

Noun phrase

The noun phrase in Khmer typically has the following structure:

Noun Phrase= (Honorific)Noun(Adjectival modifiers) (Numeral) (Classifier) (Demonstrative)

The elements in parentheses are optional.Honorificsare a class of words that serve to index the social status of the referent. Honorifics can be kinship terms or personal names, both of which are often used as first and second person pronouns, or specialized words such as/preah/('god') before royal and religious objects.The most common demonstratives are/nih/('this, these') and/nuh/('that, those'). The word/aenuh/('those over there') has a more distal or vague connotation.

If the noun phrase contains a possessive adjective, it follows the noun and precedes the numeral. If a descriptive attribute co-occurs with a possessive, the possessive construction (/rɔbɑh/) is expected.

Some examples of typical Khmer noun phrases are:

ផ្ទះ

/ptĕəh

The Khmer particle/dɑː/marked attributes in Old Khmer noun phrases and is used in formal and literary language to signify that what precedes is the noun and what follows is the attribute. Modern usage may carry the connotation of mild intensity.

/ʋiəl

srae

paddy

dɑː

ADJ.MARKER

lʋɨŋ lʋəːj/

/ʋiəl srae dɑː {lʋɨŋ lʋəːj}/

field paddy ADJ.MARKER vast

'(very) expansive fields and paddies'

Verb phrase

Khmer verbs are completely uninflected, and once a subject or topic has been introduced or is clear from context the noun phrase may be dropped. Thus, the simplest possible sentence in Khmer consists of a single verb. For example,/tɨw/'to go' on its own can mean "I'm going.", "He went.", "They've gone.", "Let's go.", etc.This also results in long strings of verbs such as:

/kʰɲom

I

cɑng

to want

tɨw

to go

daə

to walk

leːng/

to play

/kʰɲom cɑng tɨw daə leːng/

I {to want} {to go} {to walk} {to play}

'I want to go for a stroll.'

Khmer uses three verbs for what translates into English as the copula. The general copula is/ciə/;it is used to convey identity with nominal predicates.For locative predicates, the copula is/nɨw/.The verb/miən/is the "existential" copula meaning "there is" or "there exists".

'He is close to the temple.'

/miən

kaː/

plan

/miən pʰaen kaː/

to exist plan

'There is a plan.'

Negationis achieved by puttingមិន/mɨn/before the verb and the particleទេ/teː/at the end of the sentence or clause. In colloquial speech, verbs can also be negated without the need for a final particle, by placingឥត/ʔɑt/~/ʔət/before them.

/kʰɲom

I

cɨə/

to believe

/kʰɲom cɨə/

I {to believe}

'I believe.'

/kʰɲom

/kʰɲom

I

ʔɑt

NEG

cɨə/

to believe

/kʰɲom ʔɑt cɨə/

I NEG {to believe}

'I don't believe.'

Past tense can be conveyed by adverbs, such as "yesterday" or by the use of perfective particles such as/haəj/

/kŏət

he

tɨw

to go

msəlmɨɲ/

yesterday

/kŏət tɨw msəlmɨɲ/

he {to go} yesterday

'He went yesterday.'

/kŏət

he

tɨw

to go

haəj/

pfv

/kŏət tɨw haəj/

he {to go} pfv

'He left.' or 'He's already gone.'

Different senses of future action can also be expressed by the use of adverbs like "tomorrow" or by the future tense marker/nɨŋ/,which is placed immediately before the verb, or both:

/sʔaek

tomorrow

kʰɲom

I

nɨŋ

FUT

tɨw

to go

saːlaː riən/

school

/sʔaek kʰɲom nɨŋ tɨw {saːlaː riən}/

tomorrow I FUT {to go} school

'Tomorrow, I will go to school.'

Imperativesare often unmarked.For example, in addition to the meanings given above, the "sentence"/tɨw/can also mean "Go!". Various words and particles may be added to the verb to soften the command to varying degrees, including to the point of politeness (jussives):

/cou

IMP

saːk

try

lbɑːŋ

try

kʰluən

you

aeŋ

REFL

coh/

IMP

/cou saːk lbɑːŋ kʰluən aeŋ coh/

IMP try try you REFL IMP

'Go ahead and try it yourself.'

/soum

bɑndam

instruction

kŏət

he

tɨw/

IMP

/soum tʰʋəː taːm bɑndam kŏət tɨw/

please do follow instruction he IMP

'Please follow his instructions.'

Prohibitives take the form "/kom/+verb"and also are often softened by the addition of the particle/ʔəj/to the end of the phrase.

/kom

PROH

nɨw

to be

tiː

place

nih

DEM

ʔəj/

COHORT

/kom nɨw tiː nih ʔəj/

PROH {to be} place DEM COHORT

'Don't stay in this place.'

Questions

There are three basic types of questions in Khmer.Questions requesting specific information usequestion words.Polar questionsare indicated with interrogative particles, most commonly/teː/,a homonym of the negation particle.Tag questionsare indicated with various particles and rising inflection.The SVO word order is generally notinvertedfor questions.

/loːk

you

tɨw

to go

naː/

where

/loːk tɨw naː/

you {to go} where

'Where are you going?'

/loːk

you

sdap

understand

baːn

modal

teː/

Q

/loːk sdap baːn teː/

you understand modal Q

'Can you understand?'

/loːk

haəj

PRF

rɨː

or

nɨw/

yet

/loːk tɨw psaː haəj rɨː nɨw/

you {to go} market PRF or yet

'Have you gone to the store yet?'

In more formal contexts and in polite speech, questions are also marked at their beginning by the particle/taə/.

/taə

Q

loːk

you

ʔɑɲcəːɲ

to invite

tɨw

to go

naː/

where

/taə loːk ʔɑɲcəːɲ tɨw naː/

Q you {to invite} {to go} where

'Where are you going, sir?'

Passive voice

Khmer does not have a passive voice,but there is a construction utilizing the main verb/trəw/( "to hit", "to be correct", "to affect" ) as an auxiliary verb meaning "to be subject to" or "to undergo" —which results in sentences that are translated to English using the passive voice.

/piː

from

msəlmɨɲ

yesterday

kʰɲom

I

trəw

to undergo

cʰkae

dog

kʰam/

to bite

/piː msəlmɨɲ kʰɲom trəw cʰkae kʰam/

from yesterday I {to undergo} dog {to bite}

'Yesterday I was bitten by a dog.'

Clause syntax

Complex sentences are formed in Khmer by the addition of one or moreclausesto the main clause. The various types of clauses in Khmer include thecoordinate clause,therelative clauseand thesubordinate clause.Word order in clauses is the same for that of the basic sentences described above.Coordinate clauses do not necessarily have to be marked; they can simply follow one another. When explicitly marked, they are joined by words similar to English conjunctions such as/nɨŋ/( "and" ) and/haəj/( "and then" ) or by clause-final conjunction-like adverbs/dae/and/pʰɑːŋ/,both of which can mean "also" or "and also"; disjunction is indicated by/rɨː/( "or" ).

Relative clauses can be introduced by/dael/( "that" ) but, similar to coordinate clauses, often simply follow the main clause. For example, both phrases below can mean "the hospital bed that has wheels".

/krɛː

bed

pɛːt

hospital

miən

have

kɑŋ

wheel

ruɲ/

to push

/krɛː pɛːt miən kɑŋ ruɲ/

bed hospital have wheel {to push}

"the hospital bed that has wheels"

/krɛː

bed

pɛːt

hospital

dael

REL

miən

have

kɑŋ

wheel

ruɲ/

to push

/krɛː pɛːt dael miən kɑŋ ruɲ/

bed hospital REL have wheel {to push}

"the hospital bed that has wheels"

Relative clauses are more likely to be introduced with/dael/if they do not immediately follow the head noun.Khmer subordinate conjunctions always precede a subordinate clause.Subordinate conjunctions include words such as/prŭəh/( "because" ),/hakbəj/( "seems as if" ) and/daəmbəj/( "in order to" ).

Numerals

Main article:Khmer numerals

Counting in Khmer is based on abiquinarysystem: the numbers from 6 to 9 have the form "five one", "five two", etc. The words for multiples of ten from 30 to 90 are not related to the basic Khmer numbers, but are Chinese in origin, and probably came to Khmer via Thai.Khmer numerals,which were inherited directly from Indian numerals, are used more widely thanWestern numerals,which like Khmer numerals were inherited from Indian, but first passed through the Arabic numerals before reaching the west.

The principal number words are listed in the following table, which gives Western and Khmer digits, Khmer spelling and IPA transcription.

10	១០	ដប់	/ɗɑp/	dáb	100	១០០	មួយរយ	/muəjrɔːj/	muŏyrôy

Intermediate numbers are formed by compounding the above elements. Powers of ten are denoted by loan words:រយrôy/rɔːj/(100),ពាន់poăn/pŏən/(1,000),ម៉ឺនmœn/məːn/(10,000),សែនsên/saen/(100,000) andលានléan/liən/(1,000,000) from Thai andកោដិkaôdĕ/kaot/(10,000,000) from Sanskrit.

Ordinal numbersare formed by placing the particleទីti/tiː/before the corresponding cardinal number.

Social registers

Khmer employs a system ofregistersin which the speaker must always be conscious of the social status of the person spoken to. The different registers, which include those used for common speech, polite speech, speaking to or about royals and speaking to or about monks, employ alternate verbs, names of body parts and pronouns. As an example, the word for "to eat" used between intimates or in reference to animals is/siː/.Used in polite reference to commoners, it is/ɲam/.When used of those of higher social status, it is/pisa/or/tɔtuəltiən/.For monks the word is/cʰan/and for royals,/saoj/.Another result is that the pronominal system is complex and full of honorific variations, just a few of which are shown in the table below.

Writing system

Main article:Khmer script

An example of modern Khmer script at the Cambodian Embassy inBerlin

Khmer is written with the Khmer script, anabugidadeveloped from thePallava scriptof India before the 7th century when the first known inscription appeared.Written left-to-right with vowel signs that can be placed after, before, above or below the consonant they follow, the Khmer script is similar in appearance and usage toThaiandLao,both of which were based on the Khmer system. The Khmer script is also distantly related to theMon–Burmese script.Within Cambodia, literacy in the Khmer alphabet is estimated at 77.6%.

Consonant symbols in Khmer are divided into two groups, or series. The first series carries the inherent vowel[ɑː]while the second series carries the inherent vowel[ɔː].The Khmer names of the series,[akʰoːsaʔ]('voiceless') and[kʰoːsaʔ]('voiced'), respectively, indicate that the second series consonants were used to represent the voiced phonemes of Old Khmer. As the voicing of stops was lost, however, the contrast shifted to the phonation of the attached vowels, which, in turn, evolved into a simple difference of vowel quality, often bydiphthongization.This process has resulted in the Khmer alphabet having two symbols for most consonant phonemes and each vowel symbol having two possible readings, depending on the series of the initial consonant:

ត+ា	=តា	[taː]	'grandfather'
ទ+ា	=ទា	[tiə]	'duck'
