in the sentence She invented the book wagon in the early 1900's. what is the prepositional phrase and word it modifies?
Using the websites I posted for you a few minutes ago, what do you think is the prepositional phrase? What word does it modify?
I think it is in the early 1900's and the word it modifies is wagon
You've correctly identified the prepositional phrase. However, since it tells WHEN, it's an adverb phrase and modifies the verb "invented."
