Kose-Kallaste (Kose-Kaldad [pl.]): 
Waterfall by the shores, banks, riversides, etc. An odd sub-district (allasum) containing only 3 streets, each one of a different type: Kallaste tänav, Kose tee and Särgava E. allee.
Laagri (Laager) 
Camp. Laagri is both a town outside Tallinn and, due to growth, a Sub-district of Nõmme, and hence part of Tallinn (see Kaali). After the one-time POW camps set up during WWI and the Eesti Vabadussöja, or Estonian War of Independence (1918-1920), although a village already existed on the site. As the old Soviet-epoch joke went: Vabaduse puiestee viib L/laagrisse: Freedom avenue leads straight to the camp... Laagri has the highest proportion of avenues in town: 3/4 of its roads and 1/4 of all Tallinn’s, clarifying the underlying meaning of puiestee: (from, probably) puine:puise (wooden) + tee (way) where the genitive ‑se ending switched to -es out of laziness (compare Eng. curate for create and aks for ask).
Tendri (Tender)
Tender, the wagon behind the locomotive, carrying coal, other fuel or equipment. ‘Street’ renaming the former SW section of Veduri. In fact, just a gravel path from Auru connecting with Söe by a 10-plank wooden footbridge. One of a small locomotive-themed group next to Tallinn-Väike station.
Löwenruh’ (0)
The sorry equivalent, if not archetype, of “Dunroamin’”, roughly translating as The Lion’s Rest. Park in Lilleküla named after the summer estate of Friedrich von Löwen (1654-1744), Governor of Tallinn from 1728-36.
