Please help me [STRIKE]with editing[/STRIKE] to edit/correct the following sentence.
At sixty, space here the director prevailed on his deputy to retire.
Welcome to the forum. :hi:
Please note my corrections above.
1. Just saying "Help me" is impolite. You need to say "Please".
2. Ask people to help you "to + verb" or "with + noun/pronoun".
3. End every sentence with an appropriate punctuation mark.
4. Put a space after every comma, full stop, question mark and exclamation mark.
Your sentence is unclear. As Tdol pointed out, using "At sixty, the director ..." means that the director was sixty, not the deputy. As tedmc said, "prevailed on" (note that it's usually "prevail upon") is the wrong choice. Perhaps you mean "persuaded" or "encouraged".
Did you write this sentence yourself or did you find it somewhere?
