The Central Tai languages include southern dialects of Zhuang, and various Nung and Tày dialects of northern Vietnam.
Contents
Central Tai languages differ from Northern Tai languages in that Central Tai distinguishes unaspirated and aspirated onsets, while Northern Tai generally does not (Li 1977). Southwestern Tai also displays this kind of aspiration contrast.
Classification
William Gedney considers Central Tai to be more closely related to Southwestern Tai than to Northern Tai, while André-Georges Haudricourt argues for a closer relation to Northern Tai. Pittayaporn's (2009) tentative tree of the Tai branch, however, does not support the existence of Central Tai.
Certain languages in predominantly Central Tai-speaking areas, such as Caolan and Nùng An in northern Vietnam, display Northern Tai features as well. These appear to be mixed languages that are not fully Central Tai or Northern Tai. Jerold A. Edmondson calls Caolan a "tertium quid."
Languages
Many Central Tai languages are known as Nong 侬 (Nùng in Vietnamese) or Dai 岱 (Tày in Vietnamese).
