Expiration Meaning in English
word
释义
'Expiration' is the end of a period of time when something is no longer valid, good, or usable, such as food, medicine, or documents. It can also refer to the act of breathing out in medical contexts, but the time limit meaning is much more common.
用法与细微差别
Most common in formal, official, or technical contexts (foods, documents, cards). Often seen as 'expiration date.' Rarely used for 'breathing out' in everyday speech. Do not confuse with 'inspiration' (taking in air, or an idea).
