覚え方のコツ Memory Tip
原形 expire の語末の無音 e を落として -ing を付けた形で、発音は /ɪkˈspaɪərɪŋ/ です。形容詞では「すでに無効」な expired ではなく、「まもなく有効期限が終わる」段階を表します。an expiring passport、subscription、coupon のように、renew や last day と結びつけて覚えます。
Form expiring from expire by dropping the final silent e before adding -ing. In this adjectival use, it describes something approaching the end of its valid period. The key contrast is with expired: an expiring passport is still valid but will soon become invalid, whereas an expired passport has already passed its end date. Build the memory around common combinations such as an expiring subscription, expiring coupon, expiring contract, and expiring passport. These items often appear with warnings, renewal notices, or a last day for use, all of which reinforce the idea that time remains, but only briefly.
例文
Please renew your expiring passport before you travel.
旅行する前に、期限切れ間近のパスポートを更新してください。
The app warned me about my expiring subscription.
そのアプリは、まもなく期限が切れる私のサブスクリプションについて警告しました。
He used the expiring coupon on the last day.
彼は最終日に期限切れ間近のクーポンを使いました。

expiring の語源・成り立ち Etymology
expiring は expire から来て、ラテン語 expirare「息を外へ出す」が語源です。ex-「外へ」+ spirare「呼吸する」に分かれ、spirit・inspire と同根。もとは「息絶える」で、そこから期限が尽きる意味へ広がりました。
Expiring is formed from expire plus -ing, with the silent final e removed. Expire comes through French and Latin from Latin exspirare, composed of ex-, “out,” and spirare, “to breathe.” It originally conveyed breathing out and could refer to dying. From the idea of life coming to an end, the verb developed the less literal sense of a fixed period ending. That later development underlies modern phrases about expiring passports, contracts, subscriptions, and coupons.
