IPA: /ɪˌriːpɪˈlæbɪlɪti/
KK: /ɪˌriːpɪˈlæbɪlɪti/
The quality or state of something that cannot be repealed or canceled.
The irrepealability of the law ensures that it will remain in effect indefinitely.
Irrepealability → It is formed from "ir-" (meaning not), "repeal" (from Latin "repellere", meaning to drive back or revoke), and "-ability" (meaning the quality of being able to). The word refers to the quality of something that cannot be revoked or undone.
Think of 'not' ('ir-') being able to 'revoke' something ('repeal') — that's why irrepealability means it cannot be undone.
