Enlighten → It is formed from "en-" (meaning to cause to be in) and "light" (from Old English "leoht", meaning illumination or brightness). The word "enlighten" means to cause someone to gain knowledge or understanding, as if bringing light to their mind.
Think of bringing 'light' ('leoht') to someone's understanding — 'en-' means to cause to be in, so to enlighten means to cause someone to be in light or knowledge.
