What does lustral mean?
Lustral means relating to lustration, a formal act of ritual purification. Its best-known historical association is with the ancient Roman lustrum, a census and sacrificial ceremony held every five years. The Romans understood this rite to cleanse and renew the population after a plague or other crisis. The word can therefore refer more broadly to ceremonies, sacrifices, or observances intended to remove impurity and restore a community or person to a sacred condition. In modern usage, lustral is uncommon and tends to appear in historical, religious, or archaeological discussion. It should not be confused with lustrous, which means shining or glossy; the words share an appearance in print but express entirely different ideas. Lustral is normally used attributively, as in “lustral sacrifice” or “lustral ceremony,” and carries a formal, scholarly tone.

Etymology of lustral
Lustral derives from the Latin adjective lustralis, meaning “pertaining to purification.” That form was built from lustrum, the term for a purificatory sacrifice and, by extension, the Roman population census held every five years. English borrowed the adjective in the early 17th century for use in religious and historical writing.
