Origin:
1520–30; niggard + -ly
Washington, DC's black Mayor, Anthony Williams, gladly accepted the resignation of his white staff member, David Howard, because Mr. Howard uttered the word 'niggardly' in a private staff meeting.
Webster's Tenth Edition defines the word 'niggardly' to "grudgingly mean about spending or granting". The Barnhard Dictionary of Etymology traces the origins of 'niggardly' to the 1300's, and to the words 'nig' and 'ignon', meaning "miser" in Middle English. No where in any of these references is any mention of racial connotations associated with the word 'niggardly'.
