Etymology

Origin of discipline

First recorded in 1175–1225; Middle English, from Anglo-French, from Latin disciplīna “instruction, tuition,” equivalent to discipul(us) “pupil, learner, trainee” + -ina noun suffix; see origin at disciple; see -ine ²

Explanation

When you have discipline, you have self-control. When you discipline children, you are either teaching them to be well-behaved, or you are punishing and correcting them. The origins of this word offer great clues about its current meanings. The Old French descepline referred to punishment and suffering. The Latin disciplina meant "teaching, learning." The Old English version referred to a branch of knowledge or field of study (so if you're really good at word origins, you might want to make etymology your discipline). Developing discipline as a form of training is a military concept that's more than 500 years old.
