Abstract
People are crossed each other through the communication. A word is no more than one form of communication. Nevertheless, “a word”, especially speaking “the right word”, had been overestimated in “speech therapy”. Most of the people who cannot speak “the right word” were thought of as being persons with speech and language disordered. In the 1980's, “handicapped people” who raises an objection to such a point of view appeared. They wished to stop being singled out only about “the right word”. They considered expanding the power of communication important. However, people have not understood the diversity and the abundance of the communication sufficiently. Because being has an unique communication. Therefore, in this lecture, I intended to present a multilateral idea about the relation between word and communication.
