Someone asked me this question which I could not able to answer:
then my question is , " I gave a book to him"--- here why we don't use a preposition before a book? Or " he killed a snake with a stick" .. Why here is also no preposition before a snake?
I told him that this is the rule of sentence construction so we have to follow them. It also occurred to me that may be the preposition is just sandwiched between two nouns and there are no other parts of speech in between. But in this case why is there a preposition "with" after "snake".
There was another question raised by him:
"he is at home" "I gave him books" Why is there preposition "at" before "home" but not a preposition between "him" and "books"?
Please help me help him :)
