Document Summary
Children have to learn what meaning morphemes add. Children notice regularities, but this can lead them to make errors. They don"t hear adults saying it they over-regularize past tense endings. They"ve noticed the pattern of -ed ending and have over-regularized. Children also create their own ways to express meaning: Syntax has to do with knowledge of grammatical rules. It does not require an awareness of the rules. Technically need to produce two-word utterances to see evidence of syntactic development. We see children move from single-word to multiword utterances (vaguely sentence like) Telegraphic period (2-word stage; starting around 18 months) The two-word utterances are very simple -- they lack function words and word endings. But they do have some structure eat cookie" but not. By around 2 years of age, children are producing sentences with around 4 words. By 3 years, they are producing complex speech.
