A Scottish Gaelic term meaning an old woman, often used in the context of Scottish and Irish mythology as the name of a supernatural hag figure — the Cailleach — associated with winter, storms, and the creation of mountains and lochs. In everyday Scots Gaelic usage, it simply means an old woman, but in cultural and literary contexts it most commonly refers to the mythological figure, a divine hag who wields enormous power over the landscape and seasons. The word is pronounced roughly 'KAL-yuch.'

According to legend, the cailleach created Ben Nevis by dropping rocks from her apron as she strode across the Highlands.
Origin: From Scottish Gaelic 'cailleach' (old woman, hag); related to Irish Gaelic 'cailleach' and ultimately from Old Irish 'caileach,' derived from 'caille' (veil), possibly originally meaning a veiled woman or nun. Editorial expansion authored on Slangora.
