IPA: /ˌɪrɪˈpiːləbəl/
KK: /ɪˌriːˈpiːləbəl/
Something that cannot be canceled or undone, especially in the context of laws or agreements.
The new regulations are considered irrepealable, meaning they cannot be changed or removed once enacted.
Irrepealable → It is formed from "in-" (meaning not), "repeal" (from Latin "repellere", meaning to drive back or revoke), and "-able" (meaning capable of). The word means not capable of being revoked or annulled.
Think of something that cannot be 'driven back' or 'revoked' — 'in-' means not, 'repeal' means to revoke, and '-able' means capable.
