What does the word lestat mean?

"Lestat" is not a word with a common meaning in English or other major languages. It's likely you're thinking of the character Lestat de Lioncourt from Anne Rice's *Vampire Chronicles* novels.

If you're interested in the name "Lestat" itself, it's a variation of the French name "Lestat," which is derived from the Latin name "Latus," meaning "wide" or "broad."

However, in the context of Rice's novels, the name "Lestat" doesn't carry a specific meaning beyond being a fictional character's name. Anne Rice chose the name for its sound and the way it rolls off the tongue.
