In recent years, there has been an increasing body of research on Cognitive Linguistics in Brazil. However, few studies have investigated first language acquisition from a Cognitive Linguistics viewpoint. The present study is an attempt to fill in this gap. The productivity of a young Brazilian Portuguese-speaking boy with regard to the use of regular verbs was investigated at two different times: when he was 1 year and 10 months old, and when he was 2 years and 2 months old. The data were taken from the CHILDES database. Although there was a significant progress between Times 1 and 2, results suggest that the knowledge of the morphosyntax of verbs develops gradually, being initially non-schematic, which is consistent with the Cognitive Linguistics framework. The implications of these results for a theory of language acquisition are discussed.
