Etymology
The word 'expiry' originates from the Latin verb exspirare, meaning "to breathe out, to exhale one's last breath, to die". This verb is a compound of the prefix ex- ("out") and spirare ("to breathe"). The concept of breathing out one's final breath was a powerful metaphor for the termination of life. Over time, this literal sense of death broadened into the more general and abstract meaning of "coming to an end" or "ceasing to be valid", much like the final moment of a breath. The modern English noun 'expiry' retains this core logic, framing the end of a contract, license, or period as its metaphorical "last breath".
