“There are upwards of 200,000 words in the recent editions of the large dictionaries, but the one-hundredth part of this number will suffice for all your wants. Of course you may think not, and you may not be content to call things by their common names; you may be ambitious to show superiority over others and display your learning or, rather, your pedantry and lack of learning. For instance, you may not want to call a spade a spade. You may prefer to call it a spatulous device for abrading the surface of the soil. Better, however, to stick to the old familiar, simple name that your grandfather called it. It has stood the test of time, and old friends are always good friends.

To use a big word or a foreign word when a small one and a familiar one will answer the same purpose, is a sign of ignorance. Great scholars and writers and polite speakers use simple words.”
