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.
Kettler
The popularity of the Kettcar in Germany is so immense that the word "Kettcar" has become a synonym for four wheeled pedal cars and was entered into the "Duden", the official German dictionary, describing it as a "pedal powered chain vehicle for children" The first four letters of the word Kettcar are derived from the company "Kettler" and the German word for chain, "kette". The last three letters are derived from the word "car".
