Glamour
An old Scots word for an illusion cast over the eyes, later a word for allure; fairies and witches were said to cast it.
Also: glamoury, fairy glamour, enchanted sight
Glamour began as a Scots variant of grammar, a word for learning, which in the Middle Ages also carried suggestions of occult knowledge. By the eighteenth and nineteenth centuries Scottish usage meant a spell that deceives the eye, and Walter Scott helped spread this sense into standard English. Folklore tells of fairies who made leaves look like gold and old women look young. The commercial sense of fashionable charm followed in the twentieth century. Folklorists note that the belief fits a broad pattern of stories in which appearance cannot be trusted. Modern witchcraft writers use the term for a practice of changing how one is seen, which is presented as personal and symbolic.
