In order to better understand the role of the pause in the emergence of syntax in the acquisition of French, we analyzed the first two-word combinations in a longitudinal study gathering the productions of two French monolingual children, recorded between 15 and 25 months in interaction with their parents. Findings point out that the criterion of pause is very important in the construction of the first syntax, but that it must be studied relatively to other prosodic cues, such as the lengthening of the last syllable of each word and the nature of the pitch. In the lack of grammatical words, which are characteristic of the first word associations, these different parameters contribute to bring closer and reinforce the semantic cohesion within the utterance. Moreover, the data confirm the existence of a transition period of producing SSWUs (Successive Single-Word Utterances) before realization of a majority of typical two-word utterances.
