An accident is an unexpected event that happens without planning and usually causes harm, injury, damage, or loss. People often use it for things like car crashes, workplace injuries, or sudden mishaps at home.

Simple meaning

  • Something that happens suddenly and unintentionally.
  • Often unpleasant, leading to injury, damage, or loss (for example, a road accident or a fall at home).
  • You can also say you met someone “by accident,” meaning it happened by chance, not on purpose.

A kid-friendly way to say it: an accident is “something bad that happens suddenly without planning and by mistake.”

Key points people consider

  • Unplanned: No one meant for it to happen.
  • Unintended: It was not done on purpose.
  • Usually undesirable: Someone or something gets hurt or damaged.

In more formal discussions, some experts say a true accident is not only unintended but also unexpected and sometimes considered unpreventable.

Everyday examples

  • Road accidents: car crashes, motorcycle collisions, pedestrians being hit.
  • Home accidents: falling downstairs, kitchen burns, slipping in the bathroom, electric shocks.
  • School accidents: tripping in the playground, falling during sports.

All of these fit the idea of a sudden, unplanned event that causes harm.

A quick note on modern usage

In recent years, especially in road safety and news reporting, some organizations prefer words like “crash” or “collision” instead of “accident,” because “accident” can sound like nothing could be prevented. They want to highlight that many crashes involve human choices like speeding or distraction, not just “bad luck.”

TL;DR: An accident is an unplanned, unintended event—often sudden—that usually causes injury, damage, or loss, like a car crash or a fall, and it happens by chance, not on purpose.
