Etymology
Greek melan-, stem of mélās "black, dark" + -in entry 1, after Italian melaina — more at melano-
Note: The term melaina was introduced in a study of squid ink by the Italian chemist Bartolomeo Bizio (1791-1862), "Ricerche chimiche sovra l'inchiostro della Seppia," Giornale di fisica, chimica, storia naturale, medicina ed arte, decade 2, tomo 8 (1825), p. 105. Bizio formed the word from Greek mélās "black" and aeí "always" because the substance he had isolated retained its color no matter what acid or other potent chemical it was exposed to ("Questo principio animal particolarissimo il fu chiamato così dal greco mélas, nero, ed aeì sempre, che vale materia sempre nera, conciossachè gli acidi, il cloro, e tutto che vi è di più potente, non bastano a mutarlo di colore.")
