Definition of a Preposition
A preposition is a word that links a noun, pronoun, or noun phrase to some other part of the sentence.
There are approximately 80 to 100 prepositions in the English language. Prepositions are words that introduce information to the reader. This information can include where something takes place (such as ‘at’ the store), when or why something takes place (such as ‘before’ dinner), or general descriptive information (such as the girl ‘with’ the cool tattoo).
The book about the wizard
The book by the wizard
The book near the wizard
The book behind the wizard
The book under the wizard
Here is a list of common prepositions:
above, about, across, against, along, among, around, at, before, behind, below, beneath, beside, between, beyond, by, down, during, except, for, from, in, inside, into, like, near, of, off, on, since, to, toward, through, under, until, up, upon, with and within.
The Role of a Preposition
A preposition precedes a noun (or a pronoun) to show the noun’s (or the pronoun’s) relationship to another word in the sentence. In the examples above, the preposition preceded the noun wizard to show that noun’s relationship with the noun.
Here are some more examples:
It is a container for butter.
(The preposition for shows the relationship between butter and container.)
The eagle soared above the clouds.
(The preposition above shows the relationship between clouds and soared.)

A preposition is used to show direction, location, or time, or to introduce an object.
