By 18 months, a child can say how many words?

• A. 1-2 words
• B. Eight to ten words
• C. Thirty to forty words
• D. Complete sentences

Answer: (B)

By around 18 months, a child’s expressive vocabulary typically consists of about eight to ten words. This marks a stage where words begin to stand in for objects, people, and actions, moving beyond isolated babbling or single-word labels to a small but growing lexicon used in daily communication. It’s also common that they understand more words than they say at this age, so receptive vocabulary outpaces expressive. The other options describe earlier or later stages: one to two words is more typical of earlier infancy, thirty to forty words and especially complete sentences appear later, as language becomes more complex around two to three years and beyond.
