This paper provides an Optimality Theoretic analysis of the prosodic structure and stress pattern in templatic and non-templatic hypocoristics in Hebrew. It is designed to illustrate the emergence of the binary trochaic foot, whose role elsewhere in the language is otherwise limited. The binary trochaic foot has been shown to determine the structure of templatic hypocoristics in various languages. In Hebrew, however, it plays a major role also in non-templatic hypocoristics, which on the surface look like a simple construction of base-plus-suffix.
