Word Origin & Etymology

Borrowed from Late Latin illuminator ('one who gives light' or 'enlightener'), an agent noun from the verb illuminare ('to light up, make bright'), formed from in- ('into, upon') and lumen ('light'). In the Middle Ages, the term came to designate artisans who decorated manuscripts with gold and silver leaf, which literally made the parchment appear to catch and reflect light.
