Preposition

The Preposition (prep.)

A preposition is used in English to show a relationship between two words or phrases. You might recognize a preposition as being words such as in, before, on, at, to, between etc. 

Prepositions are words which link nouns, pronouns and phrases to other words in a sentence. Prepositions usually describe the position of something, the time when something happens and the way in which something is done, although the prepositions "of," "to," and "for" have some separate functions.

Examples:

In, on, at, about, apropos, according to, after, along, above, except, from, near, of, before, since, between, upon, with, to, after, toward
