Do you know ghouls from goblins and ghosts?
1789, Native Australian name, from Dharruk (language formerly spoken in the area of Sydney) /din-go/ "tame dog," though the English used it to describe wild Australian dogs. Bushmen continue to call the animal by the Dharruk term /warrigal/ "wild dog."
A hobo; tramp: One dingo got a dollar
[1920s+ Hoboes; related to the hobo sense of ding and probably ultimately to the 17th-century British slang ding-boy, ''rogue, sharper'']
