Disputed. Generally believed[1] to be from Gaulish/Transalpine Gaulish caballos.[2]. This term is cognate to Welsh ceffyl,[3][1] Manx cabbyl,[1] Scottish Gaelic and Irish capall.[1]

Also proposed is Ancient Greek καβάλλης ‎(kabállēs, nag), in turn possibly a borrowing from a Balkan, Anatolian, or north-east European language. Compare Russian кобыла ‎(kobyla), and Serbo-Croatian кобила/kobila ‎(mare).



caballus m ‎(genitive caballī); second declension

  1. horse; nag
