Rule Features

规则特征

A term used in classical transformational grammar to refer to one of the types of (binary) features which are contained in a lexical entry (the others being inherent features and contextual features), and which provides information as to whether a lexical item is exceptional with reference to the applicability of a non-lexical transformation. This type of feature is symbolized as [-Passive], [-Equi], etc. If a rule does have lexical exceptions, it is said to be governed (otherwise ungoverned).

经典转换语法术语，指包含在词条中的三类（二分）特征中的一类（另两类为固有特征和语境特征），提供有关应用非词汇转换规则时一个词项是否是例外的信息。这类特征用[-被动][-等名删除]等符号表示。一条规则如果有词汇例外就是受管辖规则（不然是不受管辖规则）。
