German orthography
Compound words, including nouns, are written together, e.g. "Haustür" (Haus+Tür; house door), "Tischlampe" (Tisch+Lampe; table lamp), "Kaltwasserhahn" (Kalt+Wasser+Hahn; cold water tap/faucet). This can lead to long words: the longest word in regular use, "Rechtsschutzversicherungsgesellschaften" ("legal protection insurance companies"), consists of 39 letters; while the longest German word ever published ("Donaudampfschiffahrtselektrizitätenhauptbetriebswerkbauunterbeamtengesellschaft", "Association for subordinate officials of the head office management of the Danube steamboat electrical services") has 79 letters.
Tuisto
The "Germania" manuscript corpus contains two primary variant readings of the name. The most frequently occurring, Tuisto, is commonly connected to the Proto-Germanic root "*twai" – "two" and its derivative "*twis" – "twice" or "doubled", thus giving Tuisto the core meaning "double". Any assumption of a gender inference is entirely conjectural, as the tvia/tvis roots are also the roots of any number of other concepts/words in the Germanic languages. Take for instance the Germanic "twist", which, in all but the English has the primary meaning of "dispute/conflict".
