luminously

The word 'luminously' traces its core to the Latin noun lumen, meaning "light." This root is shared by a family of English words concerning light, such as 'illuminate' and 'luminary.' The suffix '-ous,' borrowed from Latin via Old French, attaches to the root to form the adjective 'luminous,' meaning "full of light" or "radiant." Finally, the native English adverbial suffix '-ly' is appended, converting the descriptive quality into a manner of action, resulting in the modern sense of doing something in a radiant or brilliantly clear way.
