Abstract
While attested phonological mappings appear to be regular, Optimality Theory is known to implement more complex functions. This squib contributes to the computational characterisation of Optimality Theory by constructing a grammar that implements a non-pushdown function. By using only simple, familiar constraints, the result suggests that a large proportion of optimality-theoretic grammars are more powerful than necessary as models of phonology.
