The primary purpose of the paper is to show that such phenomena as the cliticization of weak pronouns, TH/EX in there constructions and the wh-movement from extracted nominals can fall under one generalization called "defocusing", a pragmatic operation that cannot be applied twice to the same syntactic object. We argue, in this paper, TH/EX is not a PF operation but a pragmatic operation before Spell-Out. In our model, syntactic objects should go through all the syntactic and/or pragmatic operations before they reach the interface and lexical insertion is a 24hr outlet rather than a one-fell-swoop operation.
