glamour

In the Middle Ages the meaning of grammar was not restricted to the study of language, but included learning in general. Since almost all learning was couched in language not spoken or understood by the unschooled populace, it was commonly believed that such subjects as magic and astrology were included in this broad sense of grammar. Scholars were often viewed with awe and more than a little suspicion by ordinary people. This connection between grammar and magic was evident in a number of languages, and in Scotland by the 18th century a form of grammar, altered to glamer or glamour, meant “a magic spell or enchantment.” As glamour passed into more extended English usage, it came to mean “an elusive, mysteriously exciting attractiveness.”
