Word Origin & Etymology

Borrowed in the late Middle Ages from Latin 'illuminatus', the past participle of 'illuminare' ('to light up, make bright'), formed from 'in-' ('in, upon') and 'lumen' ('light'). In medieval scriptoria, the verb also came to describe the art of adorning manuscripts with gold and silver leaf that seemed to catch and reflect light.
