Final answer:
Human language has an infinite capacity for generating very efficient messages, a feature called infinite possibilities.
Step-by-step explanation:
Human language has an infinite capacity for generating very efficient messages, a feature called infinite possibilities. Central to the infinite possibilities of language is a set of rules that govern just how sounds, signs, words, and phrases may be combined. These rules structure the order of words and dictate various aspects of communication, such as subjects, actions, and tenses. Unlike animal communication, human language is open-ended, allowing actors to combine units in an infinite number of ways to produce new meanings.
