Language is different from speech.

Speech refers to the sounds that come out of our mouth and take shape in the form of words. (e.g., children must learn how to produce the "l" sound in order to say "lamp" instead of "wamp").

Language is what we speak and understand. Language is also communicating through gestures such as body language or sign language. There are two distinct areas of language: receptive (what we hear and understand from other's speech or gestures) and expressive (the words we use to create messages others will understand).
