The element "tobar" is the Irish word for a well, and wells of this kind, known as holy wells, have been focal points of local devotion and communal ritual in Ireland for centuries, often predating Christianity and later absorbed into it. The second element, "gal", is less immediately transparent, possibly relating to a personal name or an older descriptive term, though without further documentation its precise meaning remains open.

Holy wells across Ireland tend to occupy a peculiar position in the landscape, neither fully ecclesiastical nor entirely folk in character. They are typically associated with patterns, the local assemblies held on a patron saint's feast day, during which people would walk a prescribed route around the well, recite prayers, and sometimes leave offerings such as rags, coins, or small objects tied to nearby bushes or trees. The well itself was believed to have curative or protective properties, and particular wells were often credited with healing specific ailments. Tobergal sits within this broader tradition, recorded as a monument in its own right, which suggests it retains some physical presence in the landscape, even if the details of its history and any associated devotional practice are not currently documented in the public record.
