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.
Leutnant
The German noun (with the meaning “Stellvertreter” (in English "deputy") from Middle High German «locum tenens» Platzhalter (in English "place holder") was derived from the French word «Lieutenant» about 1500. In most German-speaking armies it is the lowest officer rank (in German-speaking navies «Leutnant zur See» (English "Lieutenant at sea"). In the German Bundeswehr the ranks "Leutnant" OF1b and "Oberleutnant" OF1a belong to the "Leutnant" rank group. In some other armed forces (such as the former National People's Army) there is the lower grade of Unterleutnant (OR1c).
