To abort means to stop something before it's finished, usually because continuing would be dangerous, impossible, or no longer makes sense.

When NASA mission control aborts a rocket launch, they stop the countdown and keep the rocket on the ground because something isn't working correctly. Pilots abort landings when weather conditions suddenly become too dangerous. In these situations, aborting means making a smart decision to stop rather than pushing forward into trouble.

You might hear someone say they had to abort their camping trip when a storm rolled in, or that a teacher aborted the outdoor lesson when it started raining. The word carries a sense of necessary cancellation: you're stopping something because circumstances have changed or because you've discovered a serious problem, not simply changing your mind on a whim.

An aborted attempt is one that got started but had to be stopped partway through. Computer programs can abort operations when they detect errors. Scientists might abort an experiment if their equipment malfunctions.

The word can sound dramatic because it's often used in serious situations where safety matters, but you'll also hear it in everyday contexts where plans need to change quickly.
