Semantic Analyzability in Children’s Understanding of Idioms

This study investigated the role of semantic analyzability in children's understanding of idioms. Kindergartners and first, third, and fourth graders listened to idiomatic expressions either alone or at the end of short story contexts. Their task was to explain verbally the intended meanings of these phrases and then to choose their correct idiomatic interpretations. The idioms presented to the children differed in their degree of analyzability. Some idioms were highly analyzable or decomposable, with the meanings of their parts contributing independently to their overall figurative meanings. Other idioms were nondecomposable because it was difficult to see any relation between a phrase's individual components and the idiom's figurative meaning. The results showed that younger children (kindergartners and first graders) understood decomposable idioms better than they did nondecomposable phrases. Older children (third and fourth graders) understood both kinds of idioms equally well in supporting contexts, but were better at interpreting decomposable idioms than they were at understanding nondecomposable idioms without contextual information. These findings demonstrate that young children better understand idiomatic phrases whose individual parts independently contribute to their overall figurative meanings.
