Rotri is the Old Welsh form of Rhodri. The name derives from the elements rod meaning 'wheel' and ri meaning 'king', thus signifying 'wheel king' or 'great ruler'.EtymologyRotri is the original Old Welsh spelling of what later evolved into Rhodri in Middle Welsh. The components reflect a common Celtic naming tradition combining a noun with a royal title. The element rod appears in other Celtic names and can symbolize sovereignty or destiny.Historical ContextThe name is especially associated with Rhodri the Great (c. 820–878), also known as Rhodri ap Merfyn, a 9th-century king who ruled much of Wales. He was the first ruler to unite most of the territories under his control, earning the title "King of the Britons." While the modern form Rhodri is more common, Rotri represents the archaic spelling used in early medieval manuscripts.Notable BearersRhodri the Great (Rhodri ap Merfyn), 9th-century ruler of Gwynedd and Powys.Rhodri ap Gruffudd (d. 1219), a prince of Deheubarth.Key FactsMeaning: 'wheel king' or 'great ruler'Origin: Old WelshRelated: Rhodri (modern Welsh form)
