What is the function of recasting in child-directed speech?

The function of recasting in child-directed speech primarily involves correcting a child's incorrect utterances by restating them in a grammatically accurate manner. When adults or caregivers recast a child's speech, they typically repeat what the child said but change the incorrect parts, providing a model of the correct structure without directly pointing out the error. This not only reinforces the correct form but also encourages the child to engage further in conversation.

Through this method, children are exposed to grammatically appropriate language input, which aids in their language development by helping them learn from their mistakes in a supportive way. Recasting fosters an environment where children can comfortably experiment with language while receiving feedback that enhances their understanding and usage of language.
