Etymology

Origin of failure

First recorded in 1635–45; fail + -ure; replacing failer “a fault, default,” from Anglo-French (noun use of infinitive), for Old French faillir

Explanation

If you experience failure, things have not gone the way you'd hoped. I'm sorry to hear that your attempt to turn hay into gold has been a failure. Failure can also mean when something suddenly stops working or when you don't do something that you're expected to. A power failure might create an opportunity for a romantic candlelight dinner. Your failure to pay the electric bill may lead to a lot of romantic candlelight dinners, as long as you at least paid the gas bill. Someone who has no success in life a failure, as is an effort that doesn't work like your failure of a presidential campaign.
