The correct spelling of the word Keltane is a matter of some debate. Some versions of modern English and Scots Gaelic use the spelling Beltane for this ancient Celtic festival. However, the spelling Keltane is also commonly used by neopagan groups and scholars of Celtic culture. The IPA phonetic transcription of Keltane is /ˈkɛltən/, with stress on the first syllable. This reflects the original pronunciation of the word in Old Irish, where it was spelled Bealtaine.
