buckram

From Middle English bukeram (“fine linen”), from Anglo-Norman bokeram, from Old French boquerant, bougherant (“fine cloth”), bougueran, probably ultimately from Bokhara, a city in southeastern Uzbekistan.

Perhaps a back-formation from earlier buckrams, from buck + ramps, ramsh (“wild garlic, ramson”). Compare Danish ramsløg (“ramson”), Swedish ramslök (“bear garlic, ramson”).
