In some cases directly from Old French practique (adj.) “fit for action,” earlier pratique (13c.) and Medieval Latin practicalis, from Late Latin practicus “practical, active,” from Greek praktikos “fit for action, fit for business; business-like, practical; active, effective, vigorous,” from praktos “done; to be done,” verbal adjective of prassein, prattein “to do, act, effect, accomplish.”
