截省

A term sometimes used in syntax for a type of ellipsis, in which an interrogative item is interpreted as a complete question, the omitted material being retrieved from the previous discourse. The deletion leaves a WH-phrase, as in Somebody just left. Guess who. 

句法用来指一类省略，即一个疑问词项被理解为一个完整的问句，省略的部分可从前文找回。删除后留下一个WH-短语，如Somebody just left, Guess who.“有人刚离去，猜猜是谁”。
