Sandhi

连读变音

A term used in syntax and morphology to refer to the phonological modification of grammatical forms which have been juxtaposed. Sandhi forms are forms which have undergone specific modifications in specific circumstances (i.e. various sandhi rules have applied). Assimilation and dissimilation are two widespread tendencies which could be classified under this heading. In languages where sandhi forms are complex, a distinction is sometimes made between external sandhi (sandhi rules which operate across word boundaries) and internal sandhi (rules which operate within words).

句法学和形态学用来指两个语法形式并连时发生的音系变音。连读变音形式是在特定条件下（即已应用各种连读变音规则）发生特定音变的形式。同化和异化是归在这一名目下的两类最常见的音变。在连读变音形式很复杂的语言中，有时区分外部连读变音和内部连读变音，前者是连读变音规则的作用超出词的界限，后者是规则在词内起作用。
