Donaudampfschiffahrtselektrizitätenhauptbetriebswerkbauunterbeamtengesellschaft
Donaudampfschiffahrtselektrizitätenhauptbetriebswerkbauunterbeamtengesellschaft is a compound word that serves as an example of the virtually unlimited compounding of nouns that is possible in many Germanic languages. According to the 1996 "Guinness Book of World Records", it is the longest word published in the German language.
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.
