Peer interaction plays a significant role in children's language acquisition. When children interact with their peers, they have the opportunity to practice and refine their language skills in a natural and authentic setting. Through conversations, storytelling, and play, children learn new words, sentence structures, and communication strategies.

For example, a study by Dickinson and Tabors (2001) found that children who engaged in peer conversations showed significant improvement in their vocabulary and language development compared to those who did not have the same level of peer interaction.

Furthermore, peer interaction provides children with the chance to learn from their peers' language abilities and styles. They can observe and imitate each other's language use, leading to the development of more advanced language skills.

In conclusion, peer interaction is a crucial factor in children's language acquisition, as it provides a rich and dynamic environment for language learning and development.
