🎤Pronunciation
🌳Etymology
Origin
Derived from Latin 'expirare' (to breathe out, to die), combining ex- (out) and spirare (to breathe). Originally denoting the moment when life ends, the term evolved in modern usage to signify the date when a product's usefulness or safety concludes.
Breakdown
ex- (out, away) + spirare (to breathe) = to breathe out one's last breath. The suffix -ation converts the verb to a noun, and 'date' specifies the calendar marking of this expiration moment.
