• Objectives:

  This study investigates monolingual and code-mixed utterances in four bilingual children with different language combinations (German–English, English–Polish, Finnish–English, and French–Russian) in terms of utterance lengths (MLUs) and complexities offering a usage-based (UB) explanation based on cognitive mechanisms.

  Methodology:

  Utterances from four different child bilingual corpora were extracted and coded for individual monolingual languages and bilingual utterances.

  Data and analysis:

  35.441 utterances between the age of 2–4 were analyzed in terms of MLU and syntactic complexity.

  Findings/conclusions:

  Results showed that for all children monolingual MLUs and complexities reflect their input situations: the more input in one language, the longer and more complex those utterances were. However, in all four children code-mixed utterances were longer and more complex from the beginning of the recordings.

  Implications:

  This is the first study that systematically compares MLU scores and complexities of monolingual and bilingual utterances taking diverse language combinations into account and offering a UB explanation based on chunking and entrenchment processes as a new alternative for further research in bilingualism.
