SYNTAX: Chomsky (1998) proposes to divide lexical arrays into lexical subarrays because of the grammaticality of sentences like (i):
(i) There is a possibility that [A a proof will be discovered ]Suppose that the words in (i) are all in the same lexical array: Merge-over-Move favors merger of there over movement of a proof at stage A in the derivation, so (i) can't be derived, and we can only derive (ii):
(ii) A possibility is that there will be discovered a proof.The problem disappears if we divide the lexical array for (i) into two subarrays: one for the embedded clause (not containing there) and one for the matrix clause (containing there). (ii) can be derived by doing the opposite: selecting a subarray with an expletive for the embedded clause, and a subarray without an expletive for the matrix clause.
