Expire is from Old French expirer, from Latin exspirare "breathe out, breathe one's last, die" (ex- "out" + spirare "to breathe"). The "die" sense is the oldest in English (c. 1400); the sense used of laws, patents and treaties coming to an end appears in the mid-15c., a figurative shift already present in Latin.
expire 來自古法語 expirer、拉丁語 exspirare「呼出、嚥下最後一口氣、死去」（ex-「出去」＋ spirare「呼吸」）。在英語裡「死去」是最早的意思（約 1400 年）；用在法律、專利、條約「到期」則出現在十五世紀中葉——這個引申在拉丁文裡就已經有了。
