Overextension refers to when a child incorrectly uses a word to describe a wider set of objects or actions than the word is meant to describe. For example, a child may use the word "dog" to refer to all animals with four legs. This is different from overregularization, which refers to the overapplication of grammatical rules (e.g. "goed" instead of "went"), underextension, which refers to using a word for a narrower set of objects or actions than is appropriate (e.g. using "dog" only for their family pet), and fast mapping, which is the quick learning of new words based on context.
