niggardly:
mean or stingy person, miser," late 14c., nigard, nygard, nygart, also with a variant nigoun, nygun (c. 1300), a word of uncertain origin.
The suffix suggests French origin (see -ard), but the root word is possibly from earlier nig "stingy" (c. 1300), which is perhaps from a Scandinavian source related to Old Norse
