Which of the following best describes how children learn new vocabulary?

Children learn new vocabulary most effectively through a variety of experiences and contexts. This approach reflects the idea that vocabulary acquisition is enriched by diverse interactions with language in different situations, such as conversations with family, play with peers, exposure to books, and engagement with their environment.

When children encounter new words in varying contexts, they can grasp not only the meanings of those words but also their appropriate usage, nuances, and emotional connotations. This exposure allows them to make connections between words and the experiences they associate them with, fostering a deeper understanding and retention of vocabulary.

The other options, while they may contribute to vocabulary learning in limited ways, do not encapsulate the holistic nature of how children truly expand their vocabulary. For instance, formal schooling certainly plays a role, yet it is not the sole method by which children acquire language. Memorizing definitions might help with recall but often lacks the contextual depth necessary for meaningful understanding. Imitation of adult speech can aid vocabulary growth, but it does not encompass the broader spectrum of interactions and experiences that facilitate richer language comprehension.
