definite

The word 'definite' originates from the Latin definitus, the past participle of definire, meaning "to limit, determine, explain." This Latin verb is itself a compound of the prefix de-, which here intensifies the meaning to "completely," and finire, "to bound, limit," derived from finis ("end, boundary"). The core concept of setting a final boundary or limit evolved from the physical sense of a territorial border to the abstract sense of giving something precise, fixed, and unambiguous characteristics. Thus, the modern meaning of "clearly defined or decided" retains the original logic of an idea or object having its limits firmly and completely established.
