1481, from O.Fr.
blont, from M.L. adj.
blundus "yellow," perhaps from Frank.
*blund. If it is a Gmc. word, possibly related to O.E.
blonden-feax "gray-haired," from
blondan, blandan "to mix" (see
blend). According to Littré, the original sense of the Fr. word was "a colour midway between golden and light chestnut," which might account for the notion of "mixed." O.E.
beblonden meant "dyed," so it is also possible that the root meaning of
blonde, if it is Gmc., may be "dyed," as the ancient Teutonic warriors were noted for dying their hair. Du Cange, however, writes that
blundus was a vulgar pronunciation of L.
flavus "yellow." The word was reintroduced into Eng. 17c. from Fr., and was until recently still felt as Fr., hence
blonde for females. As a noun, used c.1755 of a type of lace, 1822 of people.
