Forms

blancus (feminine blanca, neuter blancum); first/second-declension adjective[1]

Etymology

It is borrowed from Frankish *blank (“white”),[1] from a Germanic adjective that Köbler gives as Proto-Germanic *blankaz (“white, shining”);[2][3] Niermeyer likewise calls it Germanic.[4] Köbler connects it with Proto-Indo-European *bʰleg- (“to shine, burn”).[2]

It is the source of Old French blanc,[5][6] from which English has blank and blanch.[6]

Earliest recorded meaning

Wiktionary records it as an adjective from at least the 950s, in the writings of Leo of Naples, and earlier as the byname of a Constantius Blancus in a Ravenna document of 893.[1]

Semantic evolution

Medieval writers use it for white things of every kind, such as horses, tunics and cloth.[3] In alchemy argentum or fūmus blancus was quicksilver.[3][2] As a masculine noun it named a small silver coin, French blanc;[4][7][2] the feminine named a whitish compound medicine and the neuter white lead.[3] Du Cange also records it of a white cloth in a document of 1420.[7] English blank was the name of a small French coin from the late 14th century.[6]
