Etymology

illustration = illustr<bright/enlighten> + ation<noun suffix>

  • illustr (from Latin illustrare, meaning "to light up, make clear," derived from in- (upon) + lustrare (to illuminate))
  • ation (a noun-forming suffix indicating an action or result, from Latin -atio)

Etymology Origin:
The word "illustration" traces back to the Latin illustrare, which combined the idea of "light" (lustrare) with the intensifying prefix in-. Originally, it referred to literally illuminating manuscripts with art. Over time, it evolved metaphorically to mean "clarifying" through visual or verbal examples, reflecting its dual role in both art and explanation.
