Is either wrong?
What's your take on the difference?
I'm writing my first story and have an editor who has been great. I'm going through their edits and changing my draft as per their suggestions.
One thing I'd like to check is the grammar/phrasing:
"He was chopping the onions with a professional efficiency."
- vs -
"He was chopping the onions with professional efficiency."
Is either of these wrong? And if you can explain, what's your take on the difference, if any?
