By age 3, a typical child should have a vocabulary of how many words?

A typical child by age 3 is expected to have a vocabulary that ranges from about 300 to 500 words, making option D not the appropriate answer. At this developmental stage, children are often beginning to put together simple sentences and use a growing range of words to express themselves. This rapid vocabulary development is influenced by their interactions with adults and peers, along with their experiences in various environments.

Furthermore, research on language development shows that by age 3, children typically can understand and use hundreds of words, and many start to combine words into short phrases, indicating their growing linguistic and cognitive skills. Understanding typical language development milestones helps caregivers and educators to provide appropriate support and enrich a child's learning environment through conversation and interaction.
