Bilinguals may have smaller vocabularies in each individual language, but when their vocabularies were combined, the content size was approximately similar to that of the monolingual. Monolingual children demonstrated larger vocabulary scored than their bilingual peers, but bilingual children's vocabulary scores still increased with age, just like the monolingual children's vocabulary scores (Core et al., 2011). Despite a variation in vocabulary scores, there was absolutely no difference between monolingual and bilingual children in terms of total vocabulary size and total vocabulary gains (Core et al., 2011).
