Iudris is an Old Welsh form of Idris 2, a name meaning "ardent lord" from the elements iudd "lord" and ris "ardent, enthusiastic". The name is historically attested as the moniker of Idris the Giant (Idris Gawr), a 7th-century king of Meirionnydd in Wales. In Welsh tradition, Idris was famed for his vast knowledge and was said to have been an astronomer, poet, and philosopher. The mountain Cader Idris in Gwynedd, meaning "Idris's Chair," is prophetically associated with him. Iudris represents an early medieval spelling variant of the name, reflecting the evolution of Welsh orthography during the Old Welsh period (c. 800–1100 AD). The form "Idris" became more standardized in later medieval usage and remains a common Welsh given name today. The semantic composition iudd+ris is typical of early Celtic personal names, which often combined tribal designations or honoric epithets. The name has no direct relation to the Arabic name Idris (from the prophet Enoch), though the two are occasionally conflated in multilingual contexts.
