By Sound
Louis has 路易 as its widely recognized Chinese name — the same transliteration used for Louis Vuitton and countless historical figures. 陆逸 and 洛熠 keep a close variant of the same sound while shifting the register.
By Meaning
Louis comes from the Germanic Ludwig, meaning famous warrior or renowned fighter. It carried real royal weight through eighteen French kings, though today the name's warmest association is probably Louis Armstrong — jazz legend, and about as far from battlefield renown as a name can get.
By Spirit
Louis today tends to carry warmth and soul more than martial toughness — think Armstrong's easy charisma and joyful presence. Bold, but the boldness shows up as warmth rather than force.
