noun
comma
A butterfly with a silvery comma-shaped mark on each hind wing.
A comma rests with its wings closed, revealing a silvery mark.
Etymology
Greek komma named a short clause, giving the punctuation mark its name. The butterfly borrows that mark’s name because a small silvery shape on its wing resembles a comma.
