1432, "leather pouch," from O.Fr. bougette, dim. of bouge "leather bag, wallet," from L. bulga "leather bag," of Gaulish origin (cf. O.Ir. bolg "bag," Bret. bolc'h "flax pod"), from PIE *bhelgh- (see belly). Modern financial meaning (1733) is from notion of treasury minister keeping his fiscal plans in a wallet. The verb in this sense is from 1884. Another 18c. transferred sense was to "a bundle of news," hence the use of the word as the title of some newspapers.
