The act of not renewing something, such as a contract or agreement.

Nonrenewal → It is formed from "non-" (meaning not) and "renewal" (from Latin "renovare", meaning to make new again). The word "nonrenewal" means the state of not making something new again or not renewing something.
Think of 'not' ('non-') renewing something ('renewal') — that's why nonrenewal means it hasn't been made new again.
