Strong Crossover
SYNTAX: one kind of crossover. Occurs in configurations in which a wh-element or quantificational NP undergoes A-bar movement across a pronominal which c-commands the extraction site, as in (i):
(i) *Whoi did hei see tiWho is moved across he in (i). The fact that he cannot be coindexed with ti (which would yield the reading: which x, x saw x), is referred to as 'strong crossover', because on the intended reading the structure is strongly ungrammatical. Since the wh-trace, being a variable, must be A-free, binding by he would constitute a Condition C violation. To be distinguished from weak crossover.
