"In fact, there are four main types of situation in which it is more natural to end a sentence or clause with a preposition:
passive structures (she enjoys being fussed over)
relative clauses (they must be convinced of the commitment that they are taking on)
infinitive structures (Tom had no-one to play with)
questions beginning with who, where, what, etc. (what music are you interested in?)"
Thank you. That was a really helpful guide about prepositions.
What’s the old joke? An intellectual calls out someone who finished a sentence, ‘Where’s the dog at?’
“Sir, we from Harvard never end a sentence with a preposition”.
‘Excuse me sir. I’ll rephrase. Where’s the dog at, A-hole!’
thanks
