This article describes the development of temporal reference and clause-combining in the acquisition of French L2 by adult Moroccan Arabic L1 speakers. The contribution of iconicity and of transfer from L1 in this development is discussed. The path towards grammaticalisation is less clearly marked in the domain of clause combining than in the domain of temporal reference, where after use of lexical and pragmatic means, inflection on the verb develops. Grammaticalised subordination is rarely used, except for circumstancial clauses. Paratactic devices such as clefting and NP copy tend to be used for discursive functions such as the introduction of background information in narratives, for instance.
