A study by Brown and Fraser (1963) shows that children tend to use telegraphic speech, employing content and omitting function words. This limitation involves the grammatical or semantic complexity of the sentences. Braine (1963) attempted to formulate productive rules for the initial stages in the acquisition of syntax by identifying two classes…

As may be seen from data collected during language observations of four children over a period of two and a half years, children's sentences are not simply flawed versions of adult counterparts, but seem to result from a different grammar. These data indicate that logical formatives, such as "even," and "only," are sentence-initial constituents.…

The basic-operations hypothesis predicts that for any transformation which is composed of more than one basic operation, there exists a class of errors in children's speech correctly analyzed as failure to apply one (or more) of the operations specified in the adult formulation of the rule.

The syntactic properties of the child's language are studied. Within the framework of transformational grammar, the rules of syntax can be divided into three types: base- or phrase-structure rules, transformational rules, and morphological rules. Each of these rules is discussed. It is stated that the one process that appears to characterize each…
