Unique is up on my hate list because people seem to have no idea what it means

Unless you believe there is some magical place out in the ether where word meanings reside, this is a hard statement to support. A word means what people think it means. And it might upset you that the word no longer means what it used to and what you'd like it to mean, but, alas, unique has moved on. As has peruse. Language is a cruel mistress.
