What does lunate mean?
Lunate means shaped like a crescent moon. It is used particularly when describing ornament, symbols, lettering, and historical designs whose outline suggests a thin crescent. An especially famous example is the lunate sigma, an ancient form of the Greek letter sigma whose shape resembles a curved crescent. The word can also function as a rare noun for a crescent-shaped object or mark. Although lunate is related in meaning to lunar, the two should not be confused: lunar concerns the moon itself, lunar time, or lunar cycles, while lunate specifically concerns a crescent-like shape. Lunate is most often encountered in historical writing, typography, archaeology, and descriptions of decorative art, so it has a more specialized and formal flavour than words such as crescent-shaped or curved.
