swindler

One who obtains goods on credit by false pretences, and sells them for ready money at any price, in order to make up a purse. This name is derived from the German word schwindlin, to totter, to be ready to fall ; these arts being generally practised by persons on the totter, or just ready to break. The term swindler has since been used to signify cheats of every kind.
