the.com/crescent moon
the moon showing off less than half its face and still stealing the whole sky.
means the sliver-shaped phase of the moon when less than half its disc is lit, seen either waxing (growing) or waning (shrinking).
from from latin crescere, to grow — same root as crescendo — because early skywatchers named the shape after its habit of swelling toward fullness, not its horns.
