PAN & PMP reconstructions, given for reference, are not necessarily potential cognates. They have been sourced from Blust 1999
Proto-tones are represented as A, B, C, and D. D occurs in "dead syllables" (syllables with final stops), while A, B, and C are "live syllables" (syllables ending in vowels, semivowels, and nasals). In Li's system, 1 refers to proto-voiceless initial consonants, and 2 to proto-voiced initial consonants. For D1, S refers to proto-short vowels, and L to proto-long vowels.
Where Nanna L. Jonsson does not provide any reconstructions, I have instead used Fang-Kuei Li's SW-Tai reconstructions. Li's tones differ markedly from those of Jonsson's.
I have also checked proto-forms against Titima Suthiwan's list of loanwords in Thai/Siamese (Suthiwan, Titima. 2009. "Thai vocabulary" In: Haspelmath, Martin & Tadmor, Uri (eds.) World Loanword Database. Munich: Max Planck Digital Library, 2073 entries. http://wold.livingsources.org/vocabulary/23.)
