The two creatures in the title have attracted the attention of ethnographers and etymologists alike for more than a century now, resulting in several theories, more than twenty etymologies, and no consensus. The present paper evaluates these proposals and adds to them yet another one. It also presents linguistic and extra-linguistic data that strengthens some of them and weakens others. The proposal favoured by the authors is presented in more detail, and with new supporting evidence.
