I have to identify prepositions and their objects. I was never really good at prepositions last year and still am not. Can someone please explain prepositions and their objects in detail?

Answer 1

This should explain prepositional phrases. Remember that it may modify either a noun (or pronoun) as an adjective, or a verb as an adverb. It generally tells who, what, when, how, etc. As in "He came by train." "by train" is the prepositional phrase (by is the preposition, train the object of it) and tells how "he" came. In this case it is adverbial phrase modifying "came". Read this:
