The copy theory of movement receives the strongest form of support from instances of movement leaving phonetically visible copies. Such is the case in Hebrew V(P)-fronting, where the fronted verb surfaces as an in.nitive, and its "trace" is pronounced as an inflected verbal copy. This paper argues that V-doubling is explained by the same algorithm that determines pronunciation of single copies in canonical chains. The phonetic resolution of chains is PF-internal, strictly local, and need not appeal to cross-interface recoverability constraints. Crosslinguistic variation inpredicate clefts largely reflects different morpho-phonological strategies of realizing the fronted predicate head.
