Which statement best describes the vocabulary spurt onset?

• A. Children do not show rapid growth in vocabulary.
• B. Vocabulary growth occurs gradually.
• C. The spurt occurs only after age 5.
• D. Children rapidly expand productive vocabulary around 18-24 months.

Answer: (D)

The onset of the vocabulary spurt is the moment when a child’s productive vocabulary begins to grow very quickly, typically around 18–24 months. At this stage toddlers move from knowing only a small number of words to rapidly adding new words to what they can say aloud, a burst often described as a naming explosion. This rapid production increase is what the concept captures: a sharp rise in the rate of vocabulary growth, not a slow or gradual climb, and it doesn’t occur much later like after age five. Understanding that the spurt mainly concerns productive vocabulary helps explain why this period feels especially dramatic in a child’s spoken language.
