What is the meaning of the name Belinus ?

The baby name Belinus is a Male name , 3 syllables long and is pronounced /ˈbɛlɪnəs/ (BEL-i-nus).

Belinus is Celtic, Latin in Origin.

Belinus is a Latinized Brittonic/Celtic name related to Welsh Beli and the Gaulish theonym Belenus/Belenos. Etymology points to Proto-Celtic bel-/beleno- “bright, shining,” probably from Indo‑European *bhel- “to shine, white,” yielding senses like “the shining one” or “brilliant.” In Continental Celtic religion, Belenus was a widely venerated god of light and healing; the spring festival Beltane is often connected to this root, though the link is debated.

The name enters British legend via Geoffrey of Monmouth, who lists Belinus as a pre‑Roman king and brother of Brennius; Welsh tradition remembers the cognate figure Beli Mawr (“Beli the Great”). Usage as a given name remained rare after the Middle Ages, resurfacing occasionally with antiquarian, neo‑pagan, or literary tastes. Variants and related forms include Beli, Belyn, Belin, Belinos, Belenus, and Belenos; Belina and Belena appear as modern feminine adaptations.
