Which description best characterizes language development around age 3-4 years?

• A. Learns 8-9 words per day, vocabulary about 1,000 words
• B. First words spoken
• C. Private speech begins
• D. Understands grammar relationships but cannot express them

Answer: (C)

In this age range, kids often use private speech to guide their thinking and actions. They talk aloud to themselves as they plan, solve problems, or carry out steps—planning what to do next and checking their own work. This self-talk is a normal part of development and helps children regulate their behavior and grow cognitively; over time it tends to fade as inner speech becomes more advanced. That makes the description about private speech beginning at this age the best fit. The other options don’t align as closely: the fact that first words are spoken is much earlier, during infancy; estimating a rapid daily word gain with a fixed vocabulary size doesn’t capture typical milestones for three- to four-year-olds; and by this age, children generally express grammar ideas as well as understand them, rather than being able to understand but not express.
