A prepositional phrase is a syntactic constituent headed by a preposition and typically consisting of the preposition together with its complement, which is most commonly a noun phrase or an equivalent nominal element ^[1]. As a phrase category, it is defined by the presence of a prepositional head that determines the grammatical relations between the phrase and other elements in a clause or larger phrase structure ^[1]. Prepositional phrases are distinguished from other phrase types, such as noun phrases and verb phrases, by their head category and internal organization rather than by their external grammatical function, which may vary according to syntactic context ^[2].
