A preposition is a word or phrase that introduces a noun, pronoun, adverb, or small group of words to modify some other word in the sentence. The preposition and the words, with which it combines, are known as a prepositional phrase.
- If the prepositional phrase modifies a noun or a pronoun, it is called an adjective phrase.
- If the preposition phrase modifies a verb, adjective, or adverb, it is called an adverb phrase.
A preposition always has an object.
