Imbolc
The etymology of Imbolc/Imbolg is unclear. The most common explanation is that is comes from the Old Irish "i mbolc" (Modern Irish "i mbolg"), meaning "in the belly", and refers to the pregnancy of ewes. Another possible origin is the Old Irish "imb-fholc", "to wash/cleanse oneself", referring to a ritual cleansing. Eric P. Hamp derives it from a Proto-Indo-European root meaning both "milk" and "cleansing". Professor Alan Ward derives it from the Proto-Celtic "*embibolgon", "budding". The 10th century Cormac's Glossary derives it from "oimelc", "ewe milk", but many scholars see this as a folk etymology. Nevertheless, some Neopagans have adopted "Oimelc" as a name for the festival.
