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.
Agglutination
English is capable of agglutinating morphemes of solely Germanic origin, as "un-whole-some-ness", but generally speaking the longest words are assembled from forms of Latin or Ancient Greek origin. The classic example is "antidisestablishmentarianism". Agglutinative languages often have more complex derivational agglutination than isolating languages, so they can do the same to a much larger extent. For example, in Hungarian, a word such as , which means "for [the purposes of] undenationalizationability" can find actual use. In the same way, there are the words that have meaning, but probably are never used such as , which means "like the most of most undesecratable ones of you", but is hard to decipher even for native speakers. Using inflectional agglutination, these can be extended. For example, the official Guinness world record is Finnish "I wonder if – even with his/her quality of not having been made unsystematized". It has the derived word as the root and is lengthened with the inflectional endings "-llänsäkäänköhän". However, this word is grammatically unusual, because "-kään" "also" is used only in negative clauses, but "-kö" (question) only in question clauses.
