Bile is a name from Irish mythology and possibly an Irish form of the Gaulish god-name Belenus. It may also derive from an Irish word meaning "sacred tree, scion, hero". The name appears in the Lebor Gabála Érenn (Book of Invasions), where Bile is one of the Milesians—the legendary ancestors of the Irish people—who was drowned while attempting to invade Ireland.The mythological Bile belonged to the group of invaders known as the Sons of Míl, who hailed from Scythia and eventually settled in Ireland after a series of failed landings. The name's potential connection to Belenus aligns it with a broader Celtic context; Belenus was a Gaulish deity equated with Apollo, associated with light, healing, and prophecy. The names may share an Indo-European root meaning "bright, brilliant" (from *bhel-) or "strong" (from *bel-).Despite its mythological significance, Bile is rare as a given name in modern Ireland and typically surfaces in academic or literary references rather than common usage. The name is occasionally used in historical fiction or by those seeking a connection to pre-Christian Irish heritage.Meaning: Possibly "sacred tree, scion, hero"; or from Belenus meaning "bright"Origin: Irish/CelticType: Given name (masculine)Usage: Primarily mythological, rare as a modern name
