Communication Tip #20
A preposition is something to avoid ending a sentence with. (Avoid using prepositions at the ends of sentences.)
>>From what speaker did you learn that? not: What speaker did you learn that from?
>>To whom are you listening? not: Who are you listening to?
>>For what do you need that? not: What do you need that for?
Also, some sentences should not even contain prepositions:
>>Where is he going to?
>>Where does she live at?
So, which sentence is the one with which you resonated?
