About "apologize" and "complain",
Are both phrases grammatically correct?
(1) apologize to him for being rude apologize for being rude to him
(2) complain to you of his rudeness complain of his rudeness to you
Please help me!
You probably should use sentences rather than phrases. It's often impossible to say that a phrase is correct or not.
1) These are both correct. The second is ambiguous (See below)
I will apologize to him for being rude
I will apologize for being rude to him
2) These are both alright, but "about" is better.
The second is ambiguous. It could mean the same as the first, or it could mean: I want to complain to someone else about his being rude to you.
I want to complain to you of about his rudeness
I want to complain of about his rudeness to you
