Data from Modern Hebrew support the principle of paradigm coherence and
the claim that inflection tends to minimize allomorphy while derivation
preserves it. It is shown, however, that analogical change is a function
of the degree of automaticity of the morphological and syntactic
relationships concerned, and thus close inter- paradigmatic alternations
may be subject to analogy as well. The direction of analogy can be
determined either by reference to the unmarked base form or to opacity
considerations.
