The Single Most Important Factor in Growth of Vocabulary Is

question 15

True/False

The single most important factor in growth of vocabulary is the child's language environment. Children have larger vocabularies when they are exposed to much high-quality language. The more words that children hear, the better. Specifically, children learn more words when their parents' speech is rich in different words and is grammatically sophisticated and when parents respond promptly and appropriately to their children's talk.
