history book: "...Venice was ruled by the doge..."

my brain:

*udrós 'water' was a PIE adjective

this led to English 'otter', as well as the words for 'otter' in Sanskrit (udrá), Latin (lutra) and Slavic (e.g. Czech vydra)

but, in Greek, it became húdrā 'water snake', origin of the mythological Hydra

yes, 'Hydra' and 'otter' are cognates
