glam

The word 'glam' is a 20th-century shortening of 'glamour,' which itself has a fascinating etymological journey. 'Glamour' originated in the 18th century as a Scottish alteration of the English word 'grammar.' In the medieval period, 'grammar' was associated with learning and scholarship, which to the common people seemed like occult or magical knowledge. Thus, 'glamour' first meant a magic spell or enchantment. Over time, this sense of a bewitching illusion evolved into the modern meaning of an alluring and exciting, often superficial, attractiveness associated with beauty and fashion. The clipped form 'glam' emerged in the mid-1900s, directly inheriting this sense of captivating, fashionable appeal.

This word is a shortened clipping of the longer word "glamour." It is not productively formed from independent morphemes in modern English.
