"Cailleach" is a Gaelic word, which means "old woman" or "hag." In the Scottish and Irish folklore, it refers to a divine or supernatural being that represents the harshness of winter. There are several synonyms for the word "cailleach" in the Gaelic language, such as "bheur," "bean chaointe," and "banfheinníne," all meaning "old woman" or "hag." However, in the context of its association with winter, it is referred to as "Cailleach Beinne Bric" (Hag of the Speckled Mountain), "Cailleach Bheara," and "Cailleach an Dudh-chloich" (The Dark Stone Hag). These words are not only evocative but also carry a lot of cultural significance in the Scottish and Irish traditions.
