Maybe you all have, and I'm just slow, but it really annoys me to read an article, or hear a newscast, or read a story where ordinary words are misused. My three most annoying examples are - flaunt for flout, as in "He flaunts the law," when what is meant is "He flouts the law."
Then there's "diffuse" for "defuse" ("He diffused the bomb;" interesting way to get one through a wall, I guess).
And, finally, on a story about a revolutionary war hero, the, ahem!, reporter had the man's family standing around the grave, and referred to them as his "ancestors."
Perhaps I am just too curmudgeonly, but it seems to me that if one's words are going into a public venue, one might take a bit of care to ascertain the proper word.
