First language acquisition

The study of Language by George Yule (2006)

New words
Caregiver speech: speech addressed to young children by the adult or older children who are looking after them
Cooing: the earliest use of speech-like sounds by an infant in the first few months
Holophrastic (utterance): a single form functioning as a phrase or sentence in the early speech of young children
Telegraphic speech: strings of words (lexical morphemes without inflectional morphemes) in phrases (daddy go bye-bye) produced by two-year-old children
Overgeneralization: in L1 acquisition, using an inflectional morpheme on more words than is usual in the language (two foots)
Overextension: in L1 acquisition, using a word to refer to more objects than is usual in the language (ball used to refer to the moon)
