Õie (Õis)
Flower, blossom. Known as Datši, Datschi, Datschenstraße, Villenstraße (villa) and/or Дачная ул. (dacha [the Russian dacha could take on various forms, ranging from ‘country seat’ (see Charlottentali) to cottage, referring initially to land or estates given (дача, something given, from дать, to give) to nobles by the Tsar starting in the 17th C]) until 1922 (see Köleri J.). And name changed to Tõdva from 1940-1941, presumably after the eponymous river (aka Vääna, Tedva, Hüüru, Topi and Saku), village and historical bridge in nearby Saku.
Õitse (Õitse)
Inflorescence.
Okka (Okas)
Relatively broad meanings, including thorn, spine, prick, barb, etc., but here, being a side-street to Männiku, a needle.
Õle (Õlg)
Straw or, when plural, chaff or thatch. Õlg:õla, on the other hand, is shoulder, hence any coleopteran antero-lateral elytral protuberance, although I have my doubts that this would spontaneously appeal to a street-naming committee anyway. Part of a fodder and staples street-name group. See Ädala.
