"delight"<-- de- + light <--This particular "light" comes from
"delite" (ME) <-- delit & delitier ( #OldFrench) <-- dēlectāre ( #Latin) <-- de- + laciō (Lat), in which "lacio" <-- *lakjō ( #ProtoItalic), meaning "to allure."
At some point, the spelling of "light" ("light") influenced the spelling of "delite," making the #English word seem to share the same origins.
But where the root of "light" means "to shine," the root of "lite" in "delight" means "to entice."
