Origin of jumbuckAustralian English pidgin dombock, jumbuck perhaps from Kamilaroi (Pama-Nyungan language of southeast Australia) dhimba or Malay domba ( from Persian dumba tail (as that of a fat-tailed sheep, prized for its cooking fat) ) ( from Middle Persian dumbak ) ( from Old Iranian duma- )
- (Australia) A sheep.
Unknown, from pidgin, possibly from an Australian Aboriginal language, although it appears also to have moved from pidgin to Aboriginal. Numerous derivations have been proposed.
- Mr A. Meston of Brisbane, in the Sydney Bulletin of 18 April 1896, cited Aboriginal words jimba, jombock (also jombok), dombock and dumbog, all meaning "white mist preceding a shower," which a flock of sheep supposedly resembles.
- Charles Harpur in a hand written footnote in his papers cites Aboriginal word junbuc or jimbuc (his handwriting is unclear), "a kind of kangaroo or wallaby", and states that the aborigines of the Hunter region call the sheep thus for the hairiness of one and the wooliness of the other.
- Also suggested is jumbock ("to communicate").
- An English derivation is suggested in a corruption of the phrase "jump up".
