My general theory since 1971 has been that the word is literally a virus, and that it has not been recognized as such because it has achieved a state of relatively stable symbiosis with its human host; that is to say, the word virus (the Other Half) has established itself so firmly as an accepted part of the human organism that it can now sneer at gangster viruses like smallpox and turn them in to the Pasteur Institute.
Keep your words sweet -- you may have to eat them. I expect to pass through this world but once; any good thing therefore that I can do, or any kindness that I can show to any fellow creature, let me do it now; let me not defer or neglect it, for I shall not pass this way again.
One of our defects as a nation is a tendency to use what have been called weasel words. When a weasel sucks eggs the meat is sucked out of the egg. If you use a weasel word after another there is nothing left of the other.
An average English word is four letters and a half. By hard, honest labor I've dug all the large words out of my vocabulary and shaved it down till the average is three and a half... I never write metropolis for seven cents, because I can get the same money for city. I never write policeman, because I can get the same price for cop.... I never write valetudinarian at all, for not even hunger and wretchedness can humble me to the point where I will do a word like that for seven cents; I wouldn't do it for fifteen.
