Word Origin & History

illumination 
1340, "spiritual enlightenment," from O.Fr. illumination, from L. illuminationem (nom. illuminatio), from illuminare "to throw into light," from in- "in" (with assimilation of -n- to the following consonant) + lumen (gen. luminis) "light." Meaning "the action of lighting" is from 1563. Illuminate (M.E. enlumyen) originally meant "decorate written material with gold, silver, bright colors;" sense of "shining light on" first recorded 1563. (Illumine in this sense is from 1375.)
