Expiration
“Expiration”是名词,有两种主要含义:1. 呼气的行为;呼出。2. 某事的结束或终止;当某物到期或失效时。

- “She held the breath of anticipation until expiration.” (她屏住期待的呼吸直到呼气。)
- “Check the expiration date on the milk before buying it.” (购买前检查牛奶的到期日期。)
“Expiration”来自拉丁语”expirationem”,来自”expirare”(“ex-”(“出”)+ “spirare”(“呼吸”))。
“Expiration”由前缀”ex-”(出)+ 词根”spir-”(呼吸)+ 后缀”-ation”(名词,表示行为)构成。
“Expiration”在1530年左右首次使用。这个词常用于描述合同、许可证、食品等的到期时间。
- 动词形式: “expire”(到期、呼气)
- 形容词形式: “expired”(已到期的)
“Expiration”的音标是/ˌɛk-spə-ˈreɪ-ʃən/,可以联想”ex-”(出)+ “spire”(呼吸)+ “-ation”(行为),想象呼出的行为。
