Thanks to Francois & tdol for my last problem with prefixes.
Gotta a new one for you.
"It wouldn't be of any use"
Why of? What's the structure?
Can you give me another phrase using "of" in the same way?
Or is it just a phrase that you have to remember?
I hate Engrish。。
Gotta stop trying to teach it.
Too many unanswerable questions from students.
