    From American Heritage Dictionary of the English Language, 5th Edition

  • From Middle English illuminaten, originally from Latin illūminātum, supine of illūminō (“lighten, light up, show off”), from in + lūminō (“light up”), from lūmen (“light”). Cognate with Old English lȳman (“to glow, shine”). More at leam.
