Developmental Psychology research in Brazil has made substantial progress in recent years, however, a basic process remains absent in discussions among Brazilian researchers in the area lexical development. The present paper is aimed at providing a literature review and showing how studies on word learning can contribute to our current understanding of child development. The main findings on lexical development are discussed as well as the main challenges found by researchers who are dedicated to the topic. It is also hoped that this paper can serve as a starting point for Brazilian researchers interested in investigating the process among Portuguese-speaking children.
