Failing in one's duty or obligation; behaving in a way that shows a disregard for social norms. Often refers to young people who break the law.
From Latin delinquere, combining de- (away from) and linquere (to leave). Originally meant 'to leave undone' or 'to fail in duty,' entering English in the 15th century with its current meaning developing later.
The Latin root 'linquere' also gave us 'relinquish' and 'relict,' all involving the concept of leaving behind. Interestingly, 'juvenile delinquent' as a legal category only emerged in the 19th century when society began treating young offenders differently from adult criminals.
