expire
To expire means that something has reached its end date and is no longer good or allowed to be used.
Explanation at your level:
When something has a date on it, and that date is finished, we say it expires. For example, your milk might expire today. You cannot drink it after today.
You use expire for things that have a time limit. If your passport expires, you cannot travel. If a coupon expires, you cannot use it to get a discount. It is very important to check these dates!
Expire is commonly used to describe the validity of documents or the safety of food. It is a formal way to say that something is no longer 'good.' You will often see 'Expiration Date' printed on products. If you miss this date, the item is usually considered useless or unsafe.
In professional contexts, expire refers to the termination of legal agreements or contracts. When a contract expires, the obligations of the parties involved usually end unless a renewal is negotiated. It is a precise term that helps avoid confusion in business and legal communication.
Beyond the literal, expire can occasionally be used in a metaphorical sense to describe the cessation of a feeling, a trend, or a state of being. However, its primary function remains the indication of a temporal boundary. Understanding the nuance between 'expiring' and 'terminating' is key for advanced learners; 'expire' usually implies a natural or pre-set end, whereas 'terminate' often implies an active decision.
Etymologically, the transition of expire from the biological 'exhalation of breath' to the administrative 'termination of validity' reflects a broader linguistic trend of reifying abstract concepts. In high-level academic or literary discourse, one might encounter the word used to evoke a sense of finality or the inevitable passage of time. Mastery of this word involves recognizing when it is the most precise choice versus when a synonym like 'lapse' or 'void' might be more appropriate in a specific legal or technical register.

Have you ever looked at a carton of milk and seen a date stamped on the side? That date tells you when the product will expire. When something expires, it essentially means its 'time is up' and it is no longer useful, valid, or safe to use.
Think of it like a countdown clock. Whether it is a coupon for a discount, a driver's license, or even a subscription to your favorite streaming service, these things all have an expiration date. Once that date hits, the 'magic' runs out, and you have to either renew it or replace it entirely.
The word expire has a really interesting journey! It comes from the Latin word exspirare, which literally means 'to breathe out.' In ancient times, people believed that life was tied to the breath. So, when someone died, they were literally 'breathing out' their last breath.
Over many centuries, the word moved from describing the end of a human life to describing the end of contracts, laws, and eventually, the shelf life of our groceries. It is a classic example of how language evolves from something very physical and biological to something abstract and legal!
You will hear expire used in both formal business settings and casual daily life. In business, we often talk about contracts expiring or offers expiring. It sounds professional and clear.
In your daily life, you will use it when talking about passports, credit cards, or medicine. It is a very common word, so you do not need to worry about sounding too fancy when you use it. Just remember that it is almost always used for things that have a specific time limit attached to them.
While expire is a direct verb, we have many ways to talk about things ending. 1. Past its prime: Used for food or people who are no longer at their best. 2. Run out: A very common synonym, like 'My time has run out.' 3. Reach the end of the line: When something can go no further. 4. Deadline: The literal 'death line' for a task. 5. Last leg: Used when something is about to fail or finish.
Expire is a regular verb. Its past tense is expired and the present participle is expiring. The noun form is expiration (as in 'expiration date').
Pronunciation-wise, it sounds like 'ik-SPY-er.' The stress is on the second syllable. It rhymes with words like fire, tire, wire, admire, and acquire. Make sure to clearly pronounce the 'x' sound!
