Quizplus · Accepted Answer

Fast mapping is the process of quickly learning a new word simply from hearing the contrastive use of a familiar and unfamiliar word. This is an important aspect of language acquisition and allows children to rapidly expand their vocabulary by making connections between words they already know and new words they encounter. Overextension and underextension refer to errors children make in applying words too broadly or narrowly, respectively. Holophrases are one-word utterances used by young children to express a complete thought or idea.
