What is the longest word in German?

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.
German orthography

Agglutinative languages tend to create very long words with derivational morphemes. Compounds may or may not require the use of derivational morphemes also.
The longest compounds in the world may be found in the Finnic and Germanic languages. In German, extremely 
extendable compound words can be found in the language of chemical compounds, where, in the cases of biochemistry and polymers, they can be practically unlimited in length, mostly because the German rule suggests combining all noun adjuncts with the noun as the very last stem. German examples include (color television set), (radio remote control), and the often quoted jocular word (originally only two Fs, Danube steamboat shipping company captain['s] hat), which can of course be made even longer and even more absurd, e.g. "Donaudampfschifffahrtsgesellschaftskapitänsmützenreinigungsausschreibungsverordnungsdiskussionsanfang" ("beginning of the discussion of a regulation on tendering of Danube steamboat shipping company captain hats") etc. According to several editions of the Guinness Book of World Records, the longest published German has 79 letters and is " Donaudampfschiffahrtselektrizitätenhauptbetriebswerkbauunterbeamtengesellschaft "("Association for Subordinate Officials of the Main Electric[ity] Maintenance Building of the Danube Steam Shipping"), but there is no evidence that this association ever actually existed. The word is so absurd that it was obviously invented as a joke, which is emphasized by the illogical use of the plural of "electricity".

Dutch, like many Germanic languages, is capable of forming compounds of potentially limitless length. The 53-letter word "Kindercarnavalsoptochtvoorbereidingswerkzaamhedenplan", meaning "preparation activities plan for a children's carnival procession", was cited by the 1996 Guinness Book of World Records as the longest Dutch word.

The identity of the longest word in English depends upon the definition of what constitutes a word in the English language, as well as how length should be compared. In addition to words derived naturally from the language's roots (without any known intentional invention), English allows new words to be formed by coinage and construction; place names may be considered words; technical terms may be arbitrarily long. Length may be understood in terms of orthography and number of written letters, or (less commonly) phonology and the number of phonemes.

There is some disagreement about what is the longest word in the Korean language. The longest word appearing in the "Standard Korean Dictionary" published by the National Institute of the Korean Language is (); Revised Romanization: ", which is a kind of ceramic bowl from the Goryeo dynasty; that word is 17 syllable blocks long, and contains a total of 46 hangul letters. The term (), a phonetic transcription of "nicotinamide adenine dinucleotide", has a larger number of syllable blocks (19) but a smaller number of letters (41), and also might not qualify as a single word due to the spaces.

The longest word that is not created artificially as a longest-word record seems to be at 63 letters. The word means "law delegating beef label monitoring" but as of 2013, it was removed from the books because European Union regulations have changed and that particular law became obsolete, leading to news reports that Germany "had lost its longest word".

The English word antidisestablishmentarianism (, ) is notable for its unusual length of 28 letters and 12 syllables, and is one of the longest words in the English language. It has been cited as the longest word in the English language (excluding coined and technical terms), although some sources say that it is not used enough to carry that title. The longest word found in a major dictionary is "pneumonoultramicroscopicsilicovolcanoconiosis", but this is a technical term that was coined specifically to be the longest word.
