As with life, words have plain meanings. That is, we all generally expect the basic meaning of a word to be what we know it to be through our experience and education. A “cat” does not mean a “dog.” Instead, they are what we expect them to be just as water is water and blue means blue. Without such commonly accepted meanings, we would be lost at sea, unable to communicate with one another and transmit information. Hence, shared definitions exist that typically transcend time and even cultures.
