"Waiting for" or "Awaiting for"? [closed]
The word 'wait' is used in the sense of 'remain'. On the other hand, the word 'await' is used in the sense of 'wait on' or 'expect'. This is the main difference between the two words.
Although "waiting for" is acceptable, "awaiting for" is not because "await" means "wait for". Writing "await for" would be redundant.
When sending letters by mail, you likely want to be as formal as possible. "Kindly awaiting your approval" would fit this purpose.
