Best practice
Avoid using redundant phrases like "tonight night". "Tonight" already implies the night of the current day. Use simply "tonight".
Common error
Don't repeat words that have the same meaning in a phrase. Saying "tonight night" is like saying "ATM machine" or "PIN number"—the second word is unnecessary.
