I think I said that I have roughly a decade of copy editing experience behind me (through high school, college, and three years of professional), and one of the things I've compiled in all these years is an intense dislike of certain words and phrases in the English language.
So here's the list (and if you include these in a story you send me to beta, they will be marked):
1. "Needless to say" -- If it's a phrase you don't need to say, then why are you saying it?
2. "Irregardless" -- This means the same thing as regardless, and isn't a word itself.
3. "Could care less" -- A corruption of the phrase "couldn't care less."
4. "Should of," "could of," "would of" -- I don't see this from writers so much as from non-writers. They write this when they mean "should've," "could've," or "would've."
5. "Due to the fact that" -- a wordy phrase than can easily be replaced by the word "because."
That's pretty much all I can think of right now. What are some words or phrases that bother you?
