Tai Long [thi] is listed as a separate Southwestern Tai language of Laos. The only identifying information is Louangphabang province and a speaker number of 4,800 form 2004. Tai Long (“the Great Tai”) is an ethnonym known from neighbouring Burma (and perhaps into China) to designate a fraction of the (greater) Shan but without a specific locality ( Jerold A. Edmondson 2008: 191-192 ). The speakers whose ethnonym is Tai Long in Burma speak varieties falling under the entries Shan [shn], Tai Nüa [tdd] and Lü [khb] ( Jerold A. Edmondson 2008 ). While other sources on Laos or Luang Phabang specifically (see Joachim Schliesinger 2003 and sources cited therein) do not feature a Tai group with the Tai Long, there are various pockets of Tai Nüa [tdd] and Lü [khb] speakers. It therefore stands to reason that the Tai Long in Laos also speak a variety of the Shan [shn], Tai Nüa [tdd] or Lü [khb] languages (geographically Lü [khb] may be the most likely, John F. Hartmann 2008: 255 , 261), especially in the absense of evidence of a distinct Southwestern Tai language in Luang Phabang in other sources. See also: Lü [khb], Shan [shn], Tai Nüa [tdd].
