Sisaski (Sisask)
Another of the numerous names for nightingale, this one tending to belong more to the eastern half of the country. And the more it flies, the more it changes its name, see Ööbiku. Known as Poltava (town in Ukraine) until 1925 when it morphed into Ööbiku or its alternative Ööpiku, with an interlude (1940-41) as Põdra, before realizing the name already existed and switched to its synonym in 1958 to avoid duplication.
Sitsi (Sits): 
Derived, they say, from Hindi: printed cotton or calico, perhaps सूती (sūtī), which seems to be cotton the finished product (cloth or thread) as opposed to कॉटन (kŏṭana), cotton the raw material. Renamed (1953-1990), along with Kari, as Majakovski V. during the Soviet occupation, many years prior to which, in 1820 at least, these two streets represented the approximate city boundary. One of a textile raw materials street group. See also Kanepi.
