The word "practice" traces back to Greek praktikos, emphasizing action or doing. Through Latin practicus, it entered Old French as practique, later evolving into Middle English as practise. The modern spelling "practice" (noun) and "practise" (verb, UK) reflect its dual role in describing both habitual action and professional application. The morpheme pract- retains its core meaning of "doing," while -ice solidifies it as a noun.
