practice

practice: [15] The ultimate source of practice is Greek prássein ‘do, practise’. From its base *prak- were derived the noun praxis ‘doing, action’ (source of English praxis [16]) and the adjective praktós ‘to be done’. On this was based praktikós ‘concerned with action, practical’. This passed into English via late Latin practicus as practice [14], which was later superseded by practical [17].

From practicus was derived the medieval Latin verb practicāre, later practizāre. This passed into English via Old French practiser as practise [15]. The derived noun practise was altered to practice in the 16th century, on the analogy of pairs like advice/advise.
