Discipline is the practice of making people obey rules or standards of behaviour, and punishing them when they do not.

Discipline is the quality of being able to behave and work in a controlled way which involves obeying particular rules or standards. If you discipline yourself to do something, you train yourself to behave and work in a strictly controlled and regular way.

A discipline is also a particular area of study, especially a subject of study in a college or university.
