Quick answer
An unexpected event, often unpleasant, that happens without being planned.
An accident is something bad or unexpected that happens without anyone planning it. A car crash, a fall on the stairs and a spilled cup of tea are all accidents. The word can also mean something that happens by chance, with no plan or reason, as in meeting an old friend by accident. People usually say accident for events that cause damage or injury, and a small mistake is often called an accident too. A hospital has an accident and emergency department for sudden injuries.

Origin
Accident comes from Latin accidens, the present participle of accidere, which meant to happen or to befall. The Latin verb is built from ad, meaning to, and cadere, to fall, so an accident is something that falls upon you. English had the word by the late 1300s, by way of Old French.
