IPA: /ˌɪrɪˈkʌvərəbli/
KK: /ɪrɪˈkʌvərəbli/
In a way that cannot be recovered or fixed; permanently lost or damaged.
The data was irrecoverably deleted after the system crash.
Irrecoverably → It is formed from "in-" (meaning not) and "recover" (from Latin "recuperare", meaning to regain or recover) and the suffix "-ably" (meaning in a manner that can be). The word "irrecoverably" means in a manner that cannot be regained or recovered.
Think of 'not' ('in-') being able to 'regain' ('recover') something — that's why irrecoverably means something cannot be regained.
