This paper treats the verbal morphology of Modern Hebrew (MH). Data from this system are taken as a case study for an examination of the interface between Syntax and Phonology, a.k.a Morphology. First, it is shown how the assumption that there is one single template CV-CVCVCV for all MH verbs is a valuable tool in dealing with several morpho-phonological phenomena, previously considered arbitrary. Several aspects of this template are subsequently shown to follow from the syntactic analysis of Doron 2003, if the view is adapted that morphology reflects syntax. Back to Phonology, apophony - a specific process of regular vocalic change - is shown to be motivated and brought about by syntactic structures. The findings are tested on passive verbs and proved fructuous. If so, some phonological phenomena may find explanation in syntactic structures, and nowhere else: Phonology is bound to syntax in a much tighter fashion than was previously assumed.
