Gildas is Breton in Origin.

Gildas is a masculine given name of Brittonic (Celtic) origin, best known from the 6th-century scholar-monk Gildas the Wise (Gildas Sapiens), author of De Excidio et Conquestu Britanniae. Its exact etymology is debated; proposals link it to a Celtic root meaning “pledge/hostage” (cf. Old Irish gíall) or interpret it more broadly as “servant,” so it is often glossed as “the pledged one” or “servant.”

The name travelled with insular Britons to Armorica, where Saint Gildas’s cult flourished, and it endured in Brittany, Wales, and Cornwall. It was preserved in Breton usage and saw modern revival in the 19th–20th centuries amid Breton cultural renewal, while remaining rare elsewhere. Forms and variants include French/English Gildas; Latin Gildasius; Breton Gweltaz; Portuguese Gildásio and Italian Gildasio. Place names such as Saint-Gildas-de-Rhuys attest to its lasting veneration.
