final

When used as an adjective, "final" often describes things that cannot be changed, such as a "final decision." It carries a sense of authority and completion. As a noun, "final" is commonly used in academic contexts (referring to exams) or sports (referring to the championship match). In these cases, it usually takes an article like "a final" or "the final." Be careful not to confuse "final" with "finally." While "final" describes a thing (adjective), "finally" describes how or when something happens (adverb).
