preposicional

Preposicional is an adjective in Spanish linguistics that describes anything related to or governed by prepositions. In grammars, it most often refers to a prepositional phrase, a unit formed by a preposition and its complement. In some descriptions, it also denotes a case used after prepositions in various languages.

A prepositional phrase consists of a preposition plus a noun phrase, pronoun, or clause that acts as its complement. It can function as an adverbial (modifying a verb) or an adjectival modifier (restricting a noun). The position varies but commonly appears before or after the word it modifies, and it answers questions such as where, when, how, or with whom.

Spanish examples include: "en la casa" (location), "con su amigo" (accompaniment), and "después de la reunión" (temporal). In other languages, the term also denotes a grammatical concept that marks relations with prepositions, such as a prepositional case used after certain prepositions to indicate location or topic. Russian and Polish, for instance, use forms of nouns and pronouns after prepositions to express these relations.
