NP Movement

Wh-movement is used to account for the fronting of expressions such as interrogatives. An important property of wh-movement is that the landing site of the moved expression is structurally different from the position of a subject or an object. This means that the landing site for wh-movement is higher in the clause structure than the subject position, i.e. higher than SpecIP. This is shonw in the following example:

a. [_IP Pat read the book]]
b. (I wonder) [ [which book]_i [_IP Pat read t_i] ]
