A loophole is a small mistake or gap in a law, rule, or system that people can use to avoid following the original intention. It’s like a hidden exit that lets someone escape a rule without technically breaking it.
Originally, a loophole was a narrow vertical slit in a castle wall used by archers to shoot through while staying protected. Over time, the idea of a small opening changed from a physical gap in a wall to a figurative gap in laws or rules.
