First recorded in 1350–1400; Middle English; discipline + -ed 2
Explanation
People who are disciplined are either rule-followers or they are controlled and efficient. A disciplined runner who's training for a marathon has a regular, daily exercise routine. Your disciplined puppy might be the star of her obedience class, the very best at "sit" and "stay." And your cousin who speaks six languages is also disciplined — she studies, reads, and practices speaking for hours every day. Disciplined comes from the noun discipline, which has come to mean "punishment," but is rooted in the Latin word disciplina, "teaching or knowledge," and also "military discipline."
