Vocabulary—identify the best opposite (antonym) of ‘‘COMMISSIONED’’ as used in general English usage (e.g., ‘‘a ship was commissioned’’).

Meaning in contextCOMMISSIONED (verb/adjective): formally placed into service; authorized; ordered. Example: ‘‘The warship was commissioned in 2010’’ (i.e., it officially entered active service).

Concept/ApproachWe need the closest antonym—the term that best captures the idea of officially ending or withdrawing from service (‘‘decommissioned’’).

Option analysis

• Started: could be a loose synonym (to begin), not the opposite. ❌
• Closed: context-dependent; does not specifically oppose ‘‘commissioned’’ for entities like ships/projects. ❌
• Finished: vague completion; not the institutional opposite. ❌
• Terminated: conveys officially ended/ceased, closest to ‘‘decommissioned’’. ✔️

Verification/AlternativeThe precise antonym in technical contexts is ‘‘decommissioned’’; among the given choices, ‘‘Terminated’’ most nearly matches that sense.
