preposition

This term describes a functional category of words that establish a relationship between a noun or pronoun and another part of the sentence. It typically conveys a sense of direction, location, time, or manner, acting as a bridge that provides essential spatial or temporal context.

In linguistic study, the term refers to the specific part of speech itself. While most nouns follow standard pluralization, this word is used strictly as a countable noun when referring to individual words in a language's grammar.
