How to say "to promise" in Arabic

Arabic initial و regularly matches Hebrew initial י (as in ولد/ילד), and waʿada shares its root with Hebrew יעד — but the meaning shifted: Arabic kept the speech-act sense, 'to promise', while Hebrew יעד settled on 'to designate, set aside' a time or purpose. The overlap still shows: Arabic miʿād, 'appointment', is exactly Hebrew מועד — a set time — and ועד, a committee, is literally a body appointed to meet.
