regal: [14] Regal and royal are doublets: that is to say, they come from the same ultimate source, but have diverged over the centuries. This source was rēgālis, a derivative of Latin rēx ‘king’. This came from Indo-European *rēg-, which also produced the Sanskrit ancestor of English rajah, and was a lengthened version of *reg-, source of English rector, regiment, region, regular, reign, right, rule, etc. Regal was probably borrowed direct from Latin, whereas royal was routed via Old French. Also from rēx come regalia [16] and regicide [16]. => rajah, rector, regiment, region, regular, reign, right, royal, rule
