Prepositions

Prepositions (e.g., on, in, at, and by) usually appear as part of a prepositional phrase. Their main function is to allow the noun or pronoun in the phrase to modify another word in the sentence. Prepositional phrases always begin with a preposition and end with a noun, pronoun, or other word group that functions as the object of the preposition (e.g., in time, on the table).

A preposition can be one word (e.g., about, despite, on) or a word group (e.g., according to, as well as, in spite of). Place prepositional phrases as close as possible to the words they modify. Adjectival prepositional phrases usually appear right after the noun or pronoun they modify and answer questions like Which one? and What kind of? Adverbial phrases can appear anywhere in a sentence and answer questions like When? How? and Why?

The purpose of prepositions is to express positioning for the nouns and pronouns in your sentence. The use of prepositions can be complex, making it difficult to pick the right one for a sentence. Here are some of the most common prepositions:

 about above according to across after against along along with among apart from around as as to as well as aside from at because of before behind below beneath beside between beyond by by means of by way of concerning despite down due to during except except for excepting excluding following for from in in addition to in case of in front of in place of in regard to in spite of including inside inside of into like near next to of off on on account of onto on top of out out of outside over past regarding round since through throughout till to toward under underneath unlike until up upon up to via with with reference to within with respect to without

Idiomatic prepositions

Certain verbs are followed by certain prepositions: He was listening to music. We rely on each other. Checking a verb in the dictionary will tell you which prepositions will follow it. Similarly, certain nouns and adjectives are followed by certain prepositions: He has an interest in anthropology. She puts emphasis on the importance of rules. Again, checking nouns and adjectives in the dictionary will tell you which prepositions follow it.

Adverbial and adjectival prepositional phrases

Prepositional phrases serve as adjectives or adverbs within sentences. Prepositions functioning like adverbs can go anywhere in a sentence, depending on the emphasis you want. Prepositions that function like adjectives go right after the noun they modify.

Examples:

  • Would you put your health records on the Web?
    In this sentence, on the Web is an adverbial prepositional phrase.

  • My cellphone works in Asia and Europe.
    In this sentence, in Asia and Europe is an adverbial prepositional phrase.

  • Einstein’s special theory of relativity describes the motion of particles at almost the speed of light.
    In this sentence, at almost the speed of light is an adjectival prepositional phrase.

  • Anna and Otto wrote a guide to the first year of parenthood.

    In this sentence, to the first year is an adjectival prepositional phrase – and so is of parenthood.
