A word or phrase that renames or describes another word right next to it, and is used as an apposition.
From Latin appositus (placed near), with the -ive suffix creating a noun form. Used since the 17th century as a grammatical term.
An appositive is like a second nameplate for something—'the Empire State Building, a skyscraper in New York' uses an appositive noun phrase to add instant context without needing new sentence structure.
