KK: /nɑnˈkænsləbl/
This word describes something that cannot be canceled or revoked.
The contract is noncancelable, meaning it must be honored until its term ends.
Noncancelable → It is formed from "non-" (meaning not) and "cancelable" (from Latin "cancellare", meaning to annul or make void). The word "noncancelable" means not able to be annulled or made void.
Think of 'not' ('non-') being added to 'cancelable', which means something that cannot be annulled.
