Japanese

InJapanese,the desiderative takes two main forms:-tai(-たい) and-tagaru(-たがる). Both forms conjugate for tense and positivity, but in different ways: with the-taiending, the verb becomes an-i adjective,or a conjugable adjective, while the ending-tagaru(-tai + -garusuffix) creates agodan/yodanverb. Though there are other, compound forms to demonstrate wanting, these two alone are demonstrated because they are inflections of the main verb. These two forms are plain/informal in nature, and can be elevated to the normal-polite and other levels through normal methods.

-taiis an absolute statement of desire, whereas-tagaruindicates theappearanceof desire. Generally, one does not say things such asQuá lang さんが thực べたい'Tarō wants to eat' because one cannot read Tarō's thoughts; instead, one saysQuá lang さんが thực べたがる'it appears that Tarō wants to eat.'
