IPA: /ɪnˈvaɪəblɪ/
KK: /ɪnˈvaɪəblɪ/
In a way that cannot be broken, violated, or harmed; securely and safely.
The rules must be followed inviolably to ensure fairness for everyone.
Inviolably → It is formed from "in-" (meaning not) and "violabilis" (from Latin, meaning able to be violated). The word "inviolably" means in a manner that cannot be violated or harmed.
Think of 'not' ('in-') being able to be 'violated' — that's why inviolably means something that cannot be harmed.
