Selectional Feature/ Restriction/ Rule

选择特征/限制/规则

A term in generative grammar for a type of contextual feature, i.e. a syntactic feature which specifies the conditions relating to where in a deep structure a lexical item can occur. Selectional features specify the restrictions on the permitted combinations of lexical items within a given grammatical context. These restrictions are stated with reference to the relevant inherent features in an adjacent or nearby complex symbol (within the same structural unit, i.e. they must be clause-mates).

生成语法中指一类上下文特征，即一类句法特征，它规定一个词项在深层结构可以出现在哪些位置的条件。选择特征规定某一语法上下文内允许的词项组合方式。这些限制的表述是借助一个邻接或相邻复杂符号（处于同一结构单位内，即必须是小句伙伴）的固有特征。
