Thin space

Intypography,athin spaceis aspace characterwhose width is usually1⁄5or1⁄6of anem.It is used to add a narrow space, such as between nestedquotation marksor to separateglyphsthat interfere with one another. It is not as narrow as thehair space.It is also used in theInternational System of Unitsand in many countries as athousands separatorwhen writing numbers in groups of three digits, in order to facilitate reading.^[1]It also avoids the ambiguity of the comma, used as a thousands separator in many countries but as a decimal point in Europe.

InUnicode,thin space is encoded atU+2009 THIN SPACE( ,  ). Some text editors, such as IntelliJ IDEA and Android Studio, will display the character as its suggested abbreviation of "THSP".^[2]Unicode'sU+202F NARROW NO-BREAK SPACEis anon-breaking spacewith a width similar to that of the thin space.

InLaTeXandPlain TeX,\thinspaceproduces a narrow,non-breaking space.^[3]^[4]Inside and outside of math formulae in LaTeX,\,also produces a narrow, non-breaking space.

In all versions ofLibreOfficeand in some ofMicrosoft Word,the special characters and symbolsdialog(often available viaInsert > SymbolorInsert > Special Characters), has both the thin space and the narrow no-break space available for point-and-click insertion. In LibreOffice's Symbol dialog, there is an easy-to-find box field to narrow the searching; in Word's Symbol dialog, under font = "(normal text)", the characters are found in subset = "General Punctuation", Unicode character 2009 and nearby. Other word processing programs and in many Linux configurations, have ways of producing a thin space using keyboard shortcuts.
