摘　　要：有标记的后高展唇元音/ɯ/在台语支中高频出现,并在元音系统里处于单向对立的聚合中,这使得/ɯ/要比其他元音更为易变、多变。本文发现台语支元音/ɯ/主要来源于原始台语的*ɣ:、*ɯ:、*ɯ、*ɣɯ等,其中*ɣ:和*ɯ在闭音节中形成长、短对立,*ɯ:和*ɣ:在开音节中形成高、低对立。台语支元音/ɯ/涉及的音变类型非常丰富,除了常见的高化、低化、裂化以外,还有前化、央化、圆唇化等多种变化。The high-frequency marked high back unrounded vowel/ɯ/in the Tai languages is the only one with both features of[+back,+unrounded]in the vowel system,which makes it more inconstant and variable.This paper finds that this vowel in modern Tai languages is originated mainly from*ɣ:/*ɯ:/*ɯ/*ðɯin Proto-Tai.Thence evolves from*ɣ:and*ɯ a length distinction in closed syllables,whereas from*ɯ:and*ɣ: a height distinction in open syllables in the Tai languages.A rich variety of sound change patterns can be found in the Tai languages involving the vowel/ɯ/,and in addition to the common types of heightening,lowering,diphthongization,the types of fronting,centralization,and rounding can be attested as well.
