structure. The fact that even 6- to 7-mo-olds learn words suggests
that conceptual and linguistic categories may influence one an-
other in development from the beginning (36) and that aspects of
meaning are available to guide other linguistic inferences cur-
rently thought to depend only on distributional analysis of pho-
nological regularities (37, 38). Understanding word meaning
could also support the acquisition of syntax by guiding infants’
inferences about how nouns and words from other word classes
are placed in sentences. Precocious word learning also helps
