indefinite = in<not> + definite<clearly defined>
- in-: A Latin prefix meaning "not" or "without," often used to negate the root word (e.g., invisible, inactive).
- definite: Derived from Latin definitus (past participle of definire, "to set bounds to"), combining de- (completely) + finire (to limit, from finis, "boundary").
Etymology Origin:
The word indefinite emerged in Late Middle English (15th century) via Old French indéfini, directly from Latin indefinitus. Its core logic lies in the negation (in-) of definite, which originally implied setting precise boundaries (finis = boundary in Latin). Over time, definite evolved to mean "clear" or "exact," making indefinite its natural antonym—describing things lacking clarity, duration, or specificity.
