More precisely, we analyse the relation between three aspects that are closely involved in the grammar of the verb: morphological productivity, syntactic complexity, and verb vocabulary learning. The study is based on data about the relationship between lexical development and grammatical development, and also on proposals that a critical mass of vocabulary is needed in order to develop a grammatical component. The sample comprised six subjects who are monolingual or bilingual in Catalan and/or Spanish. Results show a morphological spurt some time after the learning of a certain quantity of verbs. Moreover, syntactic complexity is only evident some months after this morphological spurt.14 p.application/pdfspa(c) Universitat de Barcelona, 2004Adquisició del llenguatgeSintaxiMorfologia (Gramàtica)Language acquisitionSyntaxMorphology (Grammar)info:eu-repo/semantics/article5253572018-03-28info:eu-repo/semantics/openAccess
