Speech and language development milestones relate to receptive language (the ability to understand words and sounds) and expressive language (the ability to use speech and gestures to communicate meaning).
A child’s speech and language development becomes more advanced beginning around age 3 through age 5. Receptive language skills during this period become more sophisticated; a child learns to make subtle distinctions between objects and relationships. Also, the child can understand multi-step requests. Most children also gradually speak more fluently and use proper grammar more consistently.
