;Dbus and Gtsang There are many
mutually intelligible Central Tibetan languages besides that of Lhasa, with particular diversity along the border and in Nepal: :
Limi (Limirong),
Mugum,
Dolpo (Dolkha),
Mustang (Lowa, Lokä),
Humla,
Nubri, Lhomi, Dhrogpai Gola,
Walungchung Gola (Walungge/Halungge),
Tseku :
Basum (most divergent, possibly a separate language)
Ethnologue reports that Walungge is highly intelligible with Thudam.
Glottolog reports these South-Western Tibetic languages as forming a separate subgroup of languages within Central Tibetan languages, but that Thudam is not a distinct variety. On the opposite,
Glottolog does not classify Basum within Central Tibetan but leaves it unclassified within Tibetic languages. Tournadre (2013) classifies Tseku with
Khams. Central Tibetan has 70% lexical similarity with
Amdo Tibetan and 80% lexical similarity with
Khams Tibetan. Qu & Jing (2017), a comparative survey of Central Tibetan lects, documents the
Lhasa,
Shigatse,
Gar,
Sherpa,
Basum,
Gertse, and
Nagqu varieties.
Ngari Tibetan Ngari Tibetan, more specifically
Stöd Ngari (as opposed to the language of pre-1842
Lower Ngari that is now an
independent language), is the endonym for a topolect spoken around
Ngari Prefecture,
T.A.R. Traditionally, it is considered a divergent variety of Dbusgtsang but not Dbusgtsang proper, however, some Western Khams Tibetan varieties such as Gêrzê Tibetan and Nagqu Tibetan are now considered part of the Ngari Tibetan areal group as well. In Indian-administrated
Tibet since the 1846 British invasion of Spiti, a related topolect is now known under the exonym "
Lahuli and Spiti". == Consonants ==
