Little words can have big meaning. What exactly are prepositions? Well, they are words that begin prepositional phrases. You may be thinking, “Okay, what the heck is a prepositional phrase?” Simply put, it’s a modifying phrase that includes a preposition and the object of the preposition (in other words, a noun). It is any word that introduces a modifying phrase that indicates time, place, direction, or introduces a particular object. There are approximately 150 prepositions in the English language, including words such as in, with, for, and about (just to name a few).

To give an example of a prepositional phrase:

She’s going to the movies.

“To the movies” indicates where the subject is going, making it a prepositional phrase. It includes the preposition “to” and the object “the movies.”

You may also see prepositional phrases with adjectives.

He’s taking her on a fun, romantic date tonight.

It’s also possible to hear people talk about prepositions followed by verbs. These are gerunds, which are -ing forms of infinitives that function as a noun in a sentence.

She won by cheating in the race.

Let’s not forget about compound prepositions, which are made up of more than one preposition. For example:

as well as
aside from
in front of
out of
