Semi-sentence

半合格句

A term used by some grammarians to refer to sentences whose grammaticality or acceptability is doubtful, but where there is sufficient plausibility of interpretation to make one unhappy about a definite judgement of ungrammaticality.

有的语法学家用来指合语法性和可接受性成问题、但理解多半不成问题因此难以断定为不合语法的那类句子。
