English Pet Peeves (ongoing)

• You don't "peek" your interest, you pique it.
• It's not your want to do something, it's your wont to do it.
• "Irregardless" is not a word, regardless of how much you want it to be.
• "An historical" is bad English (or, according to certain style guides, archaic and affected). If there's an initial 'h' pronounced, you use a.
• Speakers imply, listeners infer.
• Flammable and inflammable mean the same damn thing. (Why is that?)
• The singular of data is datum. 'Data' is PLURAL.
• You're not phased by something (unless you're in STAR TREK), you're fazed by it. Or unfazed. Pick your poison.
• As was pointed out in the comments, "I could care less" when what is meant is "I couldn't care less".
• My own inability to get comma usage correct. *growls*
• Apostrophe usage: You don't use them to make things plural (unless it's a lowercase letter), for crying out loud! This one really bothers me, so it's going to get extra space. I just read somewhere online: "Have you gotten your's yet?" GAH!
