Etymology: "Melanophores" is the plural of "melanophore," and the word is built from two Greek-derived parts. The first, "melano-," comes from Greek "melas," meaning "black" or "dark," which also appears in words such as "melancholy" (literally "black bile"). The second, "-phore," comes from Greek "phoros," meaning "bearing" or "carrying," from the verb "pherein," "to carry." Put together, the term means "dark-bearer" or "pigment-carrier," a name that describes exactly what these cells do: they hold dark pigment granules and can disperse or concentrate them, changing an animal's shade. Because the word is a modern scientific compound assembled from classical roots, it was coined by biologists rather than inherited from ancient usage, so the ancient Greeks would have recognised its parts but never this combined term.
