The time has come to write about fluff again—I ran into a comic on the subject. We curmudgeons also call fluff redundancy, wordiness, and unnecessary verbiage. Probably some saltier terms, too. Fluff is the antithesis of conciseness, the first of my gold rules for good writing.
I’ve featured this gal in Jump Start before. Several times, actually; that one was just a sample.
So when you write, look over what you wrote. (You always proofread, don’t you?) Do you see any words that you could delete without changing the meaning? Delete ’em! Your readers will thank you.
