Question

Prepositional phrases are modifiers.
True
False

Answer 1

True:

A prepositional phrase begins with a preposition and ends with an object, which is usually a noun or a pronoun.
In the sentences below, the prepositional phrases are in italics and enclosed within brackets [ ___ ]. There is an asterisk (*) after each preposition.

Please open that door [beside* you].
Thank goodness we bought that fan [by* the window].

We really needed it [during* the night].

We'd have been miserable [without* it].

Notice how the preposition in each sentence shows a relationship between the object and the word that the phrase modifies. Prepositions often show space or time relationships (as in the first three examples above) but sometimes they show other kinds of relationship (as in the fourth example above).
