What is it about?
Early lexical development is an important part of language development process. Still, it is not clear what predictions, if any, can be made based on this very early development. This paper examines the role of lexical (both receptive and expressive) development during the second year of life for the lexical, morphological and syntactical language abilities at three and a half years of age.

Why is it important?
Our findings show that especially the lexical development (both receptive and expressive) that occurs at the end of the second year of life is significantly associated with different types of language abilities a year and a half later. We also report that the best models for predicting later receptive/expressive language abilities include variables from both early receptive and expressive lexicons. These models worked very well: they explained 63/78% of the variance in receptive/expressive language abilities at three and a half years of age.
Perspectives
According to our view, this paper provides very relevant information to clinical work. It shows that measuring both receptive and expressive lexicons provides the most representative information on children’s language development. My PhD student, the first author of this paper, did a great job with this study. Preparing this manuscript together with her was a great pleasure.
