Citations for nacreous

Origin of nacreous
1830-1840
The English adjective nacreous is a derivative of nacre “mother-of-pearl.” Nacre comes from Middle French nacre, from Medieval Latin nacchara, nacara, nacrum. Other Romance languages have similar forms: Old Italian nacacra, nacchera, Catalan nacre, and Spanish nácar, all meaning “mother-of-pearl.” The further origin of nacre is uncertain: the most common etymology is that it comes from Arabic naqqāra “small drum,” or from Arabic naqur "hunting horn," a derivative of the verb nakara "hollow out," from the shape of the mollusk shell that yields mother-of-pearl. Nacreous entered English in the 19th century.
