What is a preposition?

Prepositions show direction, location, or time, or introduce an object. They are usually followed by an object—a noun, noun phrase, or pronoun. The most common prepositions are little and very common:

at, by, for, from, in, of, on, to, with

Also common are:

about, above, across, after, against, along, among, around, because of, before, behind, below, beneath, beside, between, close to, down, during, except, inside, instead of, into, like, near, off, on top of, onto, out of, outside, over, past, since, through, toward, under, until, up, upon, within, without

Prepositions typically show how the noun, noun phrase, or pronoun is related to another word in the sentence.

a friend of mine

the dress with the stripes

hit by a ball

no one except me

Prepositions with their objects form prepositional phrases. A preposition may appear at the end of a sentence or clause, but only when its object comes earlier. Contrary to what some may say, there is nothing ungrammatical about such structures.

Was he the man you worked with?

That isn't what a hammer is for.

It's the chair you're sitting on.

She just needs someone to talk to.

Many prepositions (such as past, under, off, along, and on) may also act as adverbs. A few (including before, after, for, and since) may act as conjunctions (words that join together other words or groups of words).
