abstract = {{The child directed speech of twelve English-speaking motherswas analyzed in terms of utterance-level constructions. First, the mothers{\textquotesingle} utterances were categorized in terms of general constructional categories such as Wh-questions, copulas and transitives. Second, mothers{\textquotesingle} utterances within these categories were further specified in terms of the initial words that framed the utterance, item-based phrases such as Are you {\ldots}, I{\textquotesingle}ll {\ldots}, It{\textquotesingle}s {\ldots}, Let{\textquotesingle}s {\ldots}, What did {\ldots} The findings were: (i) overall, only about 15{\textpercent} of all maternal utterances had SVO form (most were questions, imperatives, copulas, and fragments); (ii) 51{\textpercent} of all maternal utterances began with one of 52 item-based phrases, mostly consisting of two words or morphemes (45{\textpercent} began with one of just 17 words); and (iii) children used many of these same item-based phrases, in some cases at a rate that correlated highly with their own mother{\textquotesingle}s frequency of use. We suggest that analyses of adult{\textendash}child linguistic interaction should take into account not just general constructional categories, but also the item-based constructions that adults and children use and the frequency with which they use them.}},
