  • IPA (Ecclesiastical): [eɡ.zerˈt͡ʃit.t͡si.um][1]

Forms

exercitium n (genitive exercitiī or exercitī); second declension[1]

Etymology

It is from exerceō “to keep busy, train” with the suffix -ium.[2][1][3][4]

Earliest recorded meaning

Lewis and Short call it post-Augustan, absent in Cicero and Caesar, but cite a fragment of Sallust, preserved by Vegetius, on preparing soldiers by frequent exercises.[5] Köbler dates Sallust 86–34 BC.[6]

Semantic evolution

It meant exercise, training, practice, as Tacitus' cavalry drills, and in Gellius written exercises.[2][5][7] In Pliny the Elder it meant proficiency, skill.[2]

Medieval Latin used it for handling a tool, work, and for moral practice, asceticism, spiritual exercise.[8] It survives in Italian esercizio and Portuguese exercício, and Old French exercice gave English exercise in the mid-14th century, “practice for the sake of training”.[1][4]
