ramify: [16] Ramify has no connection with rams. It comes ultimately from Latin rāmus ‘branch’, which probably goes back to the same source as produced Latin rādīx ‘root’ (ancestor of English radical and radish) and English root. From it was derived the medieval Latin verb rāmificāre, which passed into English via Old French ramifier. => radical, radish[ramify etymology, ramify origin, 英语词源]
