“…The literature suggests that children are indeed able to use these to constrain verb meanings (e.g., Fisher, Hall, & Gleitman, 1994;Gleitman, 1990, for the evidence for the former source; Choi & Bowerman, 1991, for the latter). However, it is not clear how strongly these constraints are applied, or to what extent children rely on contextual and/or pragmatic information (Clark, 1997;Clark, Carpenter, & Deutsch, 1995;Tomasello, 1997), or to what extent fast-mapping is possible and successful for verbs. We would like to conclude by noting that we need to investigate lexical acquisition in a broad perspective, studying the acquisition of a wide range of lexical classes, including nouns, verbs, prepositions and classifiers, and to consider how different lexical structures influence patterns of word learning.…”
