BEWARE OF PAT EXPRESSIONS
Other things being equal, avoid phrases like "other things being equal." Those sentences that come to you whole, or in two or three doughy lumps, are sure to be bad sentences. They are no creation of yours but pieces of common thought floating in the community soup.
Pat expressions are hard, often impossible, to avoid, because they come too easily to be noticed and seem too necessary to be dispensed with. No writer avoids them altogether, but good writers avoid them more often than poor writers.
By "pat expressions" we mean such tags as "to all practical intents and purposes," "the pure and simple truth," "from where I sit," 'The time of his life," "to the ends of the earth," "in the twinkling of an eye," "as sure as you're born," "over my dead body," "under cover of darkness," "took the easy way out," "when all is said and done," "told him time and time again," "parted the best of friends," "stand up and be counted," "gave him the best years of her life," "worked her fingers to the bone." Like other cliches, these expressions were once forceful. Now we should use them only when we can't possibly think of anything else.
Some pat expressions stand like a wall between the writer and thought. Such a one is "the American way of life." Many student writers feel that when they have said that something accords with the American way of life or does not they have exhausted the subject. Actually, they have stopped at the highest level of abstraction. The American way of life is the complicated set of bonds between a hundred and eighty million ways.
All of us know this when we think about it, but the tag phrase too often keeps us from thinking about it. So with many another phrase dear to the politician: 'This great land of ours," "the man in the street," "our national heritage." These may prove our patriotism or give a clue to our political beliefs, but otherwise they add nothing to the paper except words.
