Language is the language used by Tibetans in China. It is mainly distributed in Tibet Autonomous Region and parts of Qinghai, Sichuan, Gansu and Yunnan provinces. It belongs to the Tibetan-Burmese branch of the Sino-Tibetan Language Family. Modern Tibetan has the following characteristics:

(1) Voiced consonants tend to be clearer, and the vowels retained in some areas are all from the basic vowels of the ancient complex consonants; (2) Zhao Yu simplified and disappeared the complex consonants, retaining only the duplex consonants with pre-consonants in some areas; (3) the increase of vowels, especially nasalized vowels; (4) the difference of vowels in length and length, and the disappearance of duplex consonants. There are complementary relations with intonation (5) two kinds of true complex vowel vowels: nasalization and non-nasalization; (6) the end of consonant tends to be simplified, which leads to the simplification of the end of consonant; (7) there is a complete and stable tone system, and the number of assistants tends to increase; (8) predicate is a postpositional expression system (that is, the grammatical meaning of predicate is ten thousand after predicate). (9) There are abundant reductive changes between morphemes of construction and configuration; (10) verbs only retain simplified inflectional changes, and they have lost the function of expressing grammatical meanings independently; (11) verbs have rich aspect categories; (12) judging verbs and existential verbs have two lexical forms expressing different persons; (13) verbs have no person and square. The category of position; (14) single ten thousand points deny (i.e. adding negative elements before or after the negative words); (15) there are abundant auxiliary words, and there are often two forms of reduction and independence; (16) adjectives and some derivative nouns have word-formation suffixes; (17) there are differences between honorifics and non-honorifics.

According to the structure of Tibetan:

The main verb is vgro, the tense auxiliary is rgyu, and the auxiliary verb is yiu. The combination of the three indicates that it is not possible. Such verbs, tense auxiliary verbs and auxiliary verbs are beginning to replace inflectional verb forms.

4. Single consonant finals are abundant, only VA finals begin to fall off. For example: Shan, stag lung, tshal pa, DBOS gtsang, Kun dgav blo Gros and so on. From the examples mentioned above, most of the single consonant finals in the first period of Tibetan language still exist.

5. The popular Tibetan written language has been formalized. Through the third "defining new language", the variant characters and pronunciation of the Tibetan language in the past dynasties were corrected, and the written Tibetan language was formally stereotyped. Through this standardized written language, Tibetan monks and secular scholars have translated many great works on literature, history and philosophy, among which Sakya Banzhida's Sakya Motto and Introduction to the Wise Man are the most influential ones.
