Root Explanation
Expired → It is formed from "ex-" (meaning out of) and "spirare" (meaning to breathe). The word "expired" originally referred to the act of breathing out, and in a broader sense, it means that something has come to an end or is no longer valid.
Memory Tip
Think of something that has 'breathed out' ('ex-') its time — that's why expired means it has come to an end.
