Llassar is in Origin.

Llassar is a rare Welsh given name rooted in medieval literature. In the Second Branch of the Mabinogi, Llasar Llaes Gyfnewid - together with his wife, Cymidei Cymeinfoll - brings the Cauldron of Rebirth to the court of Bendigeidfran, giving the name a distinctly mythic aura. The initial double Ll reflects the Welsh sound [ɬ], so Llassar reads roughly “HLAH-sar” to English ears.

The etymology is debated. Some scholars relate it to Welsh llasar, a word for “azure, lapis lazuli, blue pigment,” yielding a color-based sense like “the blue/azure one.” Others point to Irish lasair “flame,” suggesting “flame, blaze,” which would fit the cauldron’s fiery associations; certainty is elusive. Modern usage is extremely uncommon, though it appears in Wales and among enthusiasts of Celtic myth. Variants and cognates include Llasar (medieval spelling), anglicized Lassar, and Irish Lasair/Lasar (typically feminine).
