The pronunciation of "Beltane" is relatively consistent in both American and British English, with the primary emphasis on the first syllable. The difference might appear in the pronunciation of the second syllable, with some variance between "tayn" and a slightly softer "tuhn."
The word "Beltane" is derived from the Gaelic words "Bel," meaning 'bright' or 'brilliant,' which refers to the Celtic god of light, and "tene," meaning 'fire.' Together, they refer to the "fire of Bel." This festival's roots go back to early agrarian societies in ancient Celtic regions (what is now Ireland, Scotland, and the Isle of Man) who marked the season's transition with rituals to ensure fertility for their crops, livestock, and community. The fires, central to the celebrations, were believed to have protective powers and were symbolic of the light and warmth of the coming months.
