Etymology: Melanizing is simply the present participle of "melanize", so the story belongs to the verb it grows from. "Melanize" is built from "melanin", the dark pigment that colours skin, hair and eyes, and the suffix "-ize", which turns a noun into a verb meaning to make or cause to become something. Put together, to melanize is to cause a tissue or organism to take on melanin, which is why the word is used for the darkening of skin under sunlight. The base word itself has a Greek core. "Melanin" comes from the Greek "melas", meaning black or dark, the same root that appears in "melancholy", which literally meant black bile, one of the four humours of ancient medicine. The pigment was named in the 19th century from that classical root, so the word reflects modern scientific naming rather than any ancient usage of the pigment itself.
