Prepositional phrases begin with a preposition and end with a noun, pronoun, gerund, or clause, which serves as the object of the preposition. The object of the preposition can have modifiers describing it. Common examples of basic prepositional phrases include "at home", "in time", and "from Richie". Prepositional phrases can function as adjectives or adverbs in a sentence. As adjectives, they answer questions like "which" to modify nouns, and as adverbs they answer questions like "how", "when", or "where". It is important not to mistake the object of a prepositional phrase for the subject of a sentence.
