Exercise 6

A child's beginning sentences differ from adult sentences. A child's speech is called (a) _____ because it omits articles, prepositions, and parts of verbs. In learning the rules for combining nouns, verbs, and adjectives into meaningful sentences, children often apply a grammatical rule to cases where it should not be used. This type of error is called (b) _____. Although all children pass through these stages in the same order, they may go through them at different ages and speeds.
