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).
Most 1-year-olds begin to understand the meanings of words. Their receptive language grows from understanding names of people and objects, to being able to follow simple requests sometime between ages 1 and 2. Expressive language advances from primarily using gestures and babbling at age 1, to using words, simple phrases, and some early sentence structures between ages 2 and 3.
