Definition: The word "Appositives" refers to prepositional phrases that modify a noun, verb, or adjective. A "preposition" in English translates as a nonessential part of speech, usually serving only to clarify or point out an object or subject. Examples include "the apple," "a man," and "his wife." These words serve as adjectives modifying nouns, verbs, or adverbs. Understanding prepositional phrases is crucial for many linguistic aspects like sentence structure, word order, and figurative language.
