Variant

变体

A term used in linguistics to refer to a linguistic form which is one of a set of alternatives in a given context; it contrasts with invariant. The concept is fundamental to the notion of ALLO- (-phone, -morph, etc.), as illustrated by the variant forms of the past-tense morpheme (/-t/, /-d/, /-id/, etc.).

语言学用来指在给定上下文中一组交替形式中的语言形式。这个概念是构成“-变体”这类术语的基础（如音位变体，语素变体等），例如过去时语素的各变体形式（variant forms）（/-t/, /d/, /id/等）。
