A prepositional phrase (PP) is a linguistic construct that consists of a preposition, its object (usually a noun or pronoun), and any associated modifiers. The preposition indicates the relationship between its object and other elements in the sentence. For example, in the phrase “on the table,” “on” is the preposition, and “the table” is the object of the preposition, forming a prepositional phrase. Prepositional phrases often provide additional information about location, time, direction, or other aspects within a sentence.
