means A gentle sheen or glow reflecting off a surface — and by extension, the glamour or distinction that makes someone or something seem admirable.

from From French lustre, from Italian lustro, from the Latin verb lustrare meaning 'to illuminate' or 'to purify by ritual' — a root tangled up with lux, light itself. The Latin also carried a sense of 'to go around, survey, review,' which is why a 'lustrum' became a five-year span in Roman census cycles — an odd cousin of the shiny word sitting quietly in the dictionary's family tree.
