plumbet
/ˈplʌmɪt/(also plommett, plommet, plumette) Now rare (historical in later use)
noun
A type of fabric, usually woven from a mixture of flax and wool or silk, in contrasting shades of grey or light blue, frequently in a figured pattern. Frequently in plural.
Origin
Mid 16th century; earliest use found in Nicholas Udall (1504–1556), schoolmaster and playwright. From plumb + -et, the textile probably being so called on account of its colour which resembles that of lead; compare Old Occitan plombet greyish-blue textile, although compare also Middle French (Flanders, Picardy) plommet official leaden seal affixed to textiles to certify their quality. Compare also Middle French (Pas-de-Calais) plommet (adjective) covered with a lead varnish.
