The interrogative particles གས་, པས་, and ངས་ are not used in Literary Tibetan. Instead, we find the morpheme འམ་ and its variants (xxlink to the table called: Variant written forms of grammatical cases and morphemes), or the morpheme ཨེ་. Note that the interrogative particle ཨེ་ is placed before the verb, unlike the other interrogative particles, which go afterward. In the spoken language, ཨ་, which is related to ཨེ་, has a distinct meaning indicating doubt (not a question).
