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:
