Lõkke (Lõke)
Blaze, fire, bonfire, campfire. After the sort of things Soviet Young Pioneers (pre-Komsomol scout-like associations) would build (see street next door, Pioneeride). Previously Bienert-Straße (1879) and Erbestraße (1882) after local land-owners Friedrich Ernst Bienert, apothecary, and Eugen Eduard Erbe, town councillor.
Laulupeo (Laulupidu)
Song festival (one of the great events in the Estonian calendar). Try and imagine over 100,000 people all singing the same songs, mostly from memory, for hours on end. In comparison, a recent survey found that the average Brit knew 4.74 words ad nauseam of Auld Lang Syne. Rare in Tallinn, the street has changed its name only once (1923) since its creation as Laulupidu (see Pidu for discussion of genitive pidu/peo) in 1921 (KNAB) although TAAK says it was built for the VIIth song festival in 1910, making it even longer. Singing means something to Estonians...
Lubja (Lubi)
Lime, quicklime. Named after the former limekiln at No.11. One of a rock-based neighbourhood. See Pae.
Pärna J. (Jakob Pärn, 1843-1916)
Popular writer of (moralising) children’s books. Also, Chapter 1 of his Must Kuub (black coat, i.e., that of the traditional Estonian costume), 1913, is said to be the first major depiction of eroticism in Estonian literature. Also, and for what reason I cannot imagine, this was the first Estonian story ever translated into Finnish.
