A preposition is a word that begins a prepositional phrase and shows

the relationship between its object and another word in the sentence.

A preposition must always have an object. A prepositional phrase

starts with a preposition, ends with an object, and may have

modifiers between the preposition and object of the preposition.

Here is a list of common words that can be used as prepositions:

about, above, across, after, against, along, among, around, at,

before, behind, below, beneath, beside, besides, between, beyond, but

(when it means except), by, concerning, down, during, except, for,

from, in, inside, into, like, near, of, off, on, out, outside, over, past,

since, through, to, toward, under, until, up, upon, with, within, and


These words can be used as other parts of speech. Many of the

common words used as prepositions can be used as adverbs. They are

prepositions if they have an object to complete them. To decide

which it is, say the preposition followed by whom or what. If a noun

or a pronoun answers the question, the word is a preposition.

Example: The boy stood up and ran down the street. Up what? There

is no object; therefore up is not a preposition. Down what? Street

answers the question; therefore, down is a preposition. Down the

street is the prepositional phrase starting with the preposition down

and ending with the object street with a modifier the in between.

A prepositional phrase may be used as an adjective telling, which or

what kind, and modifying a noun or pronoun. An adjective

prepositional phrase will come right after the noun or pronoun that it

modifies. If there are two adjective prepositional phrases together,

one will follow the other. Only adjective prepositional phrases

modify the object of the preposition in another prepositional phrase.

Instructions: Pick out the adjective prepositional phrases in these

sentences and tell what they modify.
