Young children can exploit the syntactic context of a novel word to narrow down its probable meaning. This is "syntactic bootstrapping." A learner that uses syntactic bootstrapping to foster lexical acquisition must first have identified the semantic information that a syntactic context provides. Based on the "semantic seed…

The Discontinuity Model (DM) described in this article proposes that adults can learn part of L2 morphosyntax twice, in two different ways. The same item can be learned as the product of generation by a rule or as a modification of a template already stored in memory. These learning modalities, which are often seen as opposed in language theory,…

In the 1980s, researchers in child language devised several new experimental techniques to assess children's emerging linguistic competence. Innovations in methodology were needed to bridge the apparent gap between the expectation of rapid language acquisition, based on linguistic theory, and the protracted acquisition that was being witnessed…

It has been known for several decades that young children have difficulties with universal sentences. In this article, I present an analysis of the main errors that have been reported in the literature. My proposal is based on an old idea, namely, that children's errors are caused by a noncanonical mapping from syntactic form to semantic…
