True. Non-native speakers learn the language a lot more "explicitly" so they make mistakes like these a lot less often.

Another pet peeves:

"irregardless" isn't a word. It's regardless.

If you don't care about something, you "couldn't care less about it". It's simple logic and yet people mess it up all the time.

I've only noticed it enter common usage recently, but I cringe whenever someone fails at using the word "devoid".
