Kiisa (Kiisk)

Eurasian Ruffe, Gymnocephalus cernuus, member of the perch family. TT puts this in the raudteejaamade-nimeliste tänavate piirkonnas or, for those who still haven’t learned the language despite its obvious simplicity, the railway-station named street district, so he’s not confusing it with Raudkiisk (see Ogaliku), raud meaning ‘iron’ and kiiskama to glisten or sparkle as all trains should. But, as usual, he’s right, it is indeed one of the group of streets named for stations on the Tallinn-Türi Kitsarööpa line, 20-odd km to the south, so not a fish out of water. See Kohila.
