Root Breakdown
Root-derivedil- (a form of in-, 'onto') + lumin (light) + -ate (to make) = 'to throw light onto.' The sense climbs three rungs: first literal (light up a room), then artistic (monks 'illuminated' manuscripts with gold and color), then mental (illuminate a problem = make it clear). Every modern meaning is still the same gesture — aiming light at something so it can be seen.

The figurative sense is the interesting one. To illuminate an idea is a direct metaphor: a confusing thing sits in the dark, and you throw light onto it so others can see it clearly. The medieval 'illuminated manuscript' sense is a real surprise — scribes literally brightened pages with gold leaf and vivid paint, so the page itself glowed.
