This volume presents the state of the art of recent research on the acquisition of semantics. Covering topics ranging from infants' initial acquisition of word meaning to the more sophisticated mapping between structure and meaning in the syntax-semantics interface, and the relation between logical content and inferences on language meaning (semantics and pragmatics), the papers in this volume introduce the reader to the variety of ways in which children come to realize that semantic content is encoded in word meaning (for example, in the event semantics of the verbal domain or the scope of logical operators), and at the level of the sentence, which requires the composition of semantic meaning. The authors demonstrate collective expertise in a range of methodologies and topics relevant to the acquisition of semantics.
