Summary:Purpose: to check the influence of age on the lexical and grammatical performance, and investigate the correlation between the number of usual verbal description in expressive vocabulary test and measures for mean length of utterance in children with Specific Language Impairment. Method: thirty children with Specific Language Impairment between 4:0 and 6:11 year-old took part in the study, and ten were selected from each age range that had the Expressive Vocabulary Test (ABFW) and Mean Length of Utterance Test, independent gender or education. The study was retrospective, based on filming and recordings of those tests as for the data collection. Results: no statistical difference was found in the grammatical performance among ages, but positive correlation was observed among the usual verbal description and parameters MG-2 and EME-P for Mean Length of Utterance Test (p < 0.05). Conclusion: age alone is not enough to predict improvement of vocabulary and grammar; however the expansion of nouns in vocabulary promotes the increase in the length of produced utterances and the use of grammar function words. KEYWORDS: Child Language; Language Disorders; Language Tests; Vocabulary Objetivos: verificar a influencia da idade no desempenho lexical e gramatical, e investigar a existencia de correlacao entre vocabulario expressivo e as medidas de extensao media de enunciado em criancas com alteracao especifica de linguagem. Metodo: participaram do estudo trinta sujeitos com diagnostico de alteracao especifica de linguagem, entre 4:0 a 6:11 anos, sendo dez de cada faixa etaria. Todos realizaram de forma completa a prova de vocabulario expressivo (ABFW) e de Extensao Media do Enunciado, independente de genero ou escolaridade. O estudo foi retrospectivo e a coleta de dados se baseou nas filmagens e gravacoes das provas acima mencionadas. Resultados: o desempenho gramatical nao apresentou diferenca estatistica entre as idades, mas foi observada correlacao positiva entre o vocabulario expressivo e o uso de palavras de classe fechada, e entre o vocabulario expressivo e a extensao de palavras por enunciado (p-valor <0,05). Conclusao: a idade isolada nao e capaz de predizer o aprimoramento do vocabulario e da gramatica, porem a expansao do vocabulario de substantivos favorece o aumento do numero de palavras por sentenca e o uso de palavras com funcao exclusivamente gramatical.
