The Root and Meanings of Discipline
Discipline comes from discipulus, the Latin word for pupil, which also provided the source of the word disciple (albeit by way of a Late Latin sense-shift to “a follower of Jesus Christ in his lifetime”). Given that several meanings of discipline deal with study, governing one’s behavior, and instruction, one might assume that the word’s first meaning in English had to do with education. In fact, the earliest known use of discipline appears to be punishment-related; it first was used in the 13th century to refer to chastisement of a religious nature, such as self-flagellation.
