Pro-form

代形式

A term used in some models of grammatical , description to refer collectively to the items in a sentence which substitute for other items or constructions. The central class of examples is pronouns, which substitute for noun phrases. Other pro-forms replace adjective phrases, prepositional phrases, verb phrases, and even whole clauses or sentences. Terminology such as pro-verb, pro-nominal, pro-locative, pro-NP, etc., is therefore likely to be encountered.

某些语法描写模型用来统指句子中替代其他语项或构式的语项。代形式的典型例子是各种代名词，替代各种名词短语。其他代形式替代形容词短语，替代动词短语，甚至替代整个小句或句子。因此经常能见到“代词”、“代名词性成分”、“代处所词”、“代NP”这类术语。
