What does lustrate mean?
Lustrate is a rare, formal verb meaning to shine upon something or make it gleam with a bright, polished sheen. It is usually transitive: a writer may say that moonlight lustrates a lake or that a craftsperson lustrates metal before finishing it. The verb has an elevated, literary tone and is uncommon in everyday speech, so “illuminate,” “shine on,” or “polish” will often be clearer in neutral contexts. Its Latin ancestry connects it with ideas of radiance and ceremonial purification, although modern usage chiefly preserves the literal notion of light falling upon a surface. Lustrate is especially useful for precise, expressive writing about reflected light, gleam, and polish. It also reveals a root shared with words such as lustrous, luster, lustration, and illustrate.
