The input of a reduplicative word formation process in 
 Jamaican Creole (JC) is restricted prosodically. In this
 paper, the prosodic restrictions are analyzed in terms of 
 constraints that are generally operative in the JC prosodic
 system. The study therefore provides empirical support for 
 the Prosodic Morphology Hypothesis of McCarthy & Prince 
 1986. Investigation of the constraints operative in JC 
 prosody leads to two further conclusions. First, on the 
 basis of stress facts and various morpho-phonological
 phenomena, it is argued that the JC foot is a moraic 
 trochee, a member of a restrictive inventory of foot types.
 Second, the analysis of various restrictions on the 
 reduplicative base requires a loosening of the principles
 governing the layering of prosodic categories in the 
 Prosodic Hierarchy.
