Related to prepositional phrase: Infinitive phrase, prepositions
A prepositional phrase is made up of at least a preposition and its object, which can be a noun, pronoun, or a noun phrase. Often times, the object will have a modifier or modifiers (such as adjectives, noun adjuncts, etc.) that appear between it and the preposition. These specify or describe the object, but, unlike prepositions, they do not serve to connect the object grammatically to the rest of the sentence.
Prepositional phrases can behave in two ways in a sentence: as an adjective modifying a noun in the sentence, or as an adverb modifying a verb, adjective, or adverb in the sentence.
n. Abbr. PP
