By age 2 years, what language development is typical?

• A. Speaks in full sentences
• B. Uses 2-word phrases; vocabulary around 50+ words
• C. Uses only single words
• D. Understands but does not speak

Answer: (B)

At around 2 years, children typically start combining words into two-word phrases and have a vocabulary of about 50 or more words. This stage marks the move from single-word utterances toward more complex speech, with speech often telegraphic in nature (omitting small function words). They can be understood by caregivers in many contexts and can follow simple two-step commands. It’s common for understanding to outpace expressive speech at this age, and full, mature sentences aren’t yet the norm. This combination of two-word phrases plus a vocabulary around 50+ words best fits typical language development at this age.
