In language development, what milestone is typically observed by 1 year?

• A. Speaks in full sentences
• B. Understands complex grammar
• C. Says "mama" and "dada" nonspecific; responds to own name; understands simple commands
• D. Reads simple words

Answer: (C)

At about 12 months, language shows both growing understanding and the emergence of early words. Children often say a few words with meaning, but those words are frequently nonspecific, like "mama" or "dada" used without clear reference. They also start to respond to their own name and understand simple commands or gestures, showing that receptive language is developing. This combination—nonspecific first words, recognizing their name, and following simple directions—fits the typical 1-year milestone.

By contrast, speaking in full sentences is a toddler skill that develops later, after age 2. Understanding complex grammar isn’t expected at this age, and reading simple words is far beyond what a 1-year-old can do.
