木雅语共有7个表示不同方向的趋向前缀,每个趋向前缀存在多个不同的表层形态,这些表层形态均是从同一种底层形态演变而来的,RTR(舌根后缩)元音和谐现象以及具有语法功能的前缀-i或-u的存在,是其主要变体条件。其中,前缀-i为使动前缀;-u为第三人称施者论元标记(3A),或为木雅语另一个使动前缀。 There are altogether seven tending prefixes in different directions in Muya language. There are several different topographic patterns for each trending prefix. These topographic patterns all evolve from the same underlying morphology. The vowel harmony (RTR) As well as the presence of the syntactically functional prefix -i or -u, are the main variant conditions. Here, the prefix -i is the dynamic prefix; -u is the third-person implementer’s meta-signature (3A), or the other dynamic prefix.
