Modern Standard Tibetan grammar

Tibetan grammar describes the morphology, syntax and other grammatical features of Standard Tibetan, a Sino-Tibetan language. Standard Tibetan is typologically an ergative–absolutive language. Nouns are generally unmarked for grammatical number, but are marked for case. Adjectives are never marked and appear after the noun. Demonstratives also come after the noun but these are marked for number. Verbs are possibly the most complicated part of Tibetan grammar in terms of morphology. The dialect described here is the colloquial language of Central Tibet, especially Lhasa and the surrounding area, but the spelling used reflects classical Tibetan, not the colloquial pronunciation.

Nouns are not usually marked for grammatical gender or number.

Natural gender may be conveyed through the lexicon, e.g. གཡག་ <gyag> "yak (male)," འབྲི་ <'bri> "yak-cow." In human or animate nouns, gender may be indicated through suffixes. These suffixes are generally པ་ <pa> or པོ་ <po> "male," and མ་ <ma> or མོ་ <mo> "female."

Number is never marked in inanimate nouns or animals. Even human nouns can only take the plural marker ཚོ་ <tsho> if they are specified or definite, e.g. ཨ་མ་ <a-ma> "mother" → ཨ་མ་ཚོ་ <a-ma-tsho> "(the) mothers." Tibetan does not mark definiteness, and such a meaning would be left to be deduced from the context.

Tibetan nouns are marked for six cases: absolutive, agentive, genitive, ablative, associative and oblique. Particles are attached to entire noun phrases, not to individual nouns. Case suffixes are attached to the noun phrase as a whole, while the actual noun remains unchanged. The form taken by the suffix depends on the final sound of the noun to which the suffix is attached.
