Dzayul County also has Khams Tibetan speakers who had originally migrated from the Lamo-speaking area of Dongba Township, Dzogang County. Jiang (2022) refers to the language as ''Suku'' or ''Sukuhua'' (素苦话).

Classification

Suzuki & Nyima (2016, 2018) suggest that Lamo may be a Qiangic language. Guillaume Jacques (2016)Jacques, Guillaumes. 2016
Les journées d'études sur les langues du Sichuan
suggests that mBo is a rGyalrongic language belonging to the Stau- Khroskyabs (Horpa-Lavrung) branch.

Suzuki & Nyima (2018) note that Lamo is closely related to two other recently documented languages of Chamdo, eastern Tibet, namely Larong (spoken in the Lancang River valley of Zogang County and Markam County) and Drag-yab (spoken in southern Zhag'yab County). These languages together are called the Chamdo languages.

Lexicon

Suzuki & Nyima (2016) list the following Lamo words.

Phonology

Suzuki & Nyima (2018) report the phonology of the Kyilwa dialect. They have drawn the conclusion that Lamo "tends to have a different phonetic development from the others".

Prenasalisation and preaspiration appear as a preinitial.

All of these vowels have creaky and nasalized counterparts. There are a few secondary articulations found marginally, namely retroflexed /ɚ/ and velarized /ə^ɣ/.

Syllable structure: ^cCGV

The tones are high and rising, the same as in Larong and Drag-yab. The tone bearing unit is the first two syllables of every word. The second syllable is occasionally excluded from the TBU.
