Abstract

The issue of language acquisition has been approached from a variety of viewpoints. One field of investigation is learnability. What properties of universal grammar makes it possible that grammars of individual languages can actually be learned? OT assumes that UG defines a set of universal and violable constraints, as well as principles by which constraints interact. Individual languages differ along the dimension of constraint ranking. If grammars are essentially rankings of universal constraints, then acquiring a language must involve the acquisition of a language-specific hierarchy of universal constraints. The language learner has exclusive access to the output forms of the target language, and is faced with the task of extracting the information form these outputs that is necessary to rank all constraints in a way predicting the outputs.
