SBARQ|Direct question introduced by a wh-word or wh-phrase. See Section 5.32. Indirect questions and relative clauses should be bracketed as SBAR, not SBARQ. (Santorini 1991) Wh-questions should be bracketed as SBARQ. The wh-constituent (whether it is a subject or not) is a child of SBARQ; the rest of the question is an SQ. If the wh-constituent is a subject or an object, the position where it is interpreted should be represented by the empty element T. (Santorini 1991) The SBARQ label marks wh-questions (i.e., those that contain a gap and therefore require a trace). A further level of structure, SQ, contains the inverted auxiliary (if there is one) and the rest of the sentence. The inverted auxiliary in wh-questions is not labeled. ...
