Which word means 'not able to be changed or reversed'?

• A. Irrevocable
• B. Provisional
• C. Sincere
• D. Indigenous

Answer: (A)

Understanding this term means recognizing final, unchangeable outcomes. Irrevocable describes something that cannot be changed or undone once it’s set. It’s built from the idea of revoke—to call back or cancel—and the prefix ir- meaning not, plus the suffix able meaning capable of. So ir+revocable = not able to be revoked, i.e., not able to be changed or reversed. Provisional is the opposite in meaning—temporary or conditional, likely to change. Sincere means genuine or honest. Indigenous means native to a region. These don’t fit the idea of something that cannot be altered or undone.
