Both Khams Tibetan and Lhasa Tibetan evolve to not preserve the word-initialconsonant clusters,[3] which makes them very far fromClassical Tibetan, especially when compared to the moreconservativeAmdo Tibetan.[4][5] Also, Kham and Lhasa Tibetan evolved to betonal, which Classical Tibetan was not.[3] Khams Tibetan has 80% lexical similarity with Central Tibetan.[6]
Kham Tibetan is spoken inKham, which is now divided between the eastern part ofTibet Autonomous Region, the southern part of Qinghai, the western part ofSichuan, and the northwestern part ofYunnan, China.
Khampa Tibetan is also spoken by about 1,000 people in two enclaves in easternBhutan, the descendants of pastoral yak-herding communities.[7]
TheGêrzê dialect is sometimes consideredWestern Khams.
These have relatively lowmutual intelligibility, but are close enough that they are usually considered a single language. Khamba is more divergent, but classified with Khams byGeorge Van Driem.[8]
Thephonologies and vocabularies of the Bodgrong, Dartsendo, dGudzong, Khyungpo (Khromtshang), Lhagang Rangakha, Sangdam, Sogpho, sKobsteng, sPomtserag, Tsharethong, and Yangthang dialects of Kham Tibetan have been documented by Hiroyuki Suzuki.[10]
/x,xʰ,ɣ/ before front vowels/i,e,ø,ɛ/ are realized as palatal fricatives[ç,çʰ,ʝ].
Palatal plosives/c,ɟ/ are included in the consonant inventory of the dGudzong dialect, but these sound values may include a phonetic variant of palatalised velar plosives. The velar plosive series generally do not include a phonetic variant of palatal plosives. These two series, therefore, are still distinctive, but it is supposed that they may merge into velar ones in the near future.[16]
/tʂ,tʂʰ,dʐ/ are heard as plosives[ʈ,ʈʰ,ɖ] in the dGudzong dialect of the rGyalrong area.
/ɬ/ may also be heard as a voiceless lateral[l̥] in free variation.[17]
