common mistakes in english

what is common mistake in english?

Using "alot" for "a lot".
EX: Thanks *alot. => Thanks a lot. (the symbol * means ungrammatical)

Using "it's" (it is) for "its" (possessive pronoun).
EX: *It's tooth is loose. => Its tooth is loose.

Confusing words: there, their, they're; except/accept; to, too, two
