Which milestone occurs by 2-3 years, relating to vocabulary at 24 months?

• A. Knows about 50 words at 24 months
• B. Understands time sequences
• C. Follows simple commands without gestures
• D. Describes complex sequences

Answer: (A)

By 24 months, vocabulary growth is typically around 50 words. This milestone captures the rapid expansion of a toddler’s spoken lexicon at this age, where they begin labeling familiar objects and people and may start combining a couple of words. Reaching about 50 words by two years is a common benchmark used to gauge expressive language development and helps indicate the child is moving from gesture-based communication toward more verbal expression.

Other skills listed relate to different aspects of development. Understanding time sequences is a cognitive milestone that develops over the toddler years and becomes clearer later. Following simple commands without gestures is a receptive language ability that can vary and isn’t the primary marker of vocabulary size at this age. Describing complex sequences is a skill that emerges much later in preschool years.
