two others that accompany language are paralanguage, a system of extralinguistic noises that have meaning, and kinesics, a system of body motions used to convey messages.
Both represent survivals of the gesture-call system relied upon by other primates, such as monkeys and apes, to communicate their current states of being(contented, irritated, uncomfortable, sleepy, restless, and so forth) as well as their immediate intentions.
