"Prof. E. B. Tylor informs me that the name of 'bull-roarer' was first introduced into anthropological literature by the Rev. Lorimer Fison, who compares the Australian tundun to 'the wooden toy which I remember to have made as a boy, called a 'bull-roarer',' and this term has since been universally adopted as the technical name for the implement." [Fison and Howitt, Kamilaroi and Kurnai, 1880. p. 267.] Wikipedia article on subject of bullroarer. The bull-roarer has been found in pretty well every culture- one was found in Turkey eight & a half thousand years ago. But of all languages Turkish does not seem to have a Turkish equivalent word. All the Romantic languages have a word, either derived from the Greek rhombus or onomatopoeic. See http://www.bramadera.es/index_en.html. Please try to give me a proper equivalent in Turkish.
