Infants learn the forms of words by listening to the speech they hear. Though little is known about the degree to which these forms are meaningful for young infants, the words still play a role in early language development. Words guide the infant to his or her first syntactic intuitions, aid in the development of the lexicon, and, it is proposed, may help infants learn phonetic categories.
婴儿通过聆听他们所听到的言语来学习单词的形式。尽管对于这些形式对幼儿的意义程度知之甚少,但这些词仍然在早期语言发展中发挥作用。这些词引导婴儿形成最初的句法直觉,帮助词汇的发展,并且有人提出,这些词可能有助于婴儿学习语音类别。
