Think you’re unique? Great! Think you’re very unique? You’re not.
That’s because there’s no such thing as being “very” unique, or “somewhat” unique, or “more” unique than the other folks.
The word “unique” is powerful because it has one meaning. Something that’s unique is “singular” or “one of a kind.” Only one. No others. No comparison. It either is, or it isn’t. No in-between, no wiggle room. That’s why you shouldn’t attach a modifier to it.
Why do we so many people and companies modify that powerful word? I blame a lack of confidence. If we (or our attorneys) aren’t completely sure that what we’re writing about is unique, we soften it by adding a modifier. Don’t do that. If you’re not 100 percent confident that what you’re describing is unique, choose another word.
