Compound (linguistics)
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".
Elbe (ship)
Elbe, was a 1,693 ton, three-masted, iron sailing ship with a length of 257 feet, breadth of 38.2 feet and depth of 23.1 feet. She was built by Russel & Company in Glasgow for the Nourse Line, named after the River Elbe the longest river in Germany and launched in July 1887. She was primarily used for the transportation of Indian indentured labourers to the colonies. Details of some of these voyages are as follows:"Elbe"s third trip to Fiji was historic because it brought the first labourers from Madras to Fiji for the first time. Most South Indians were Tamil speakers but other languages such as Telugu and Malayalam were also represented. Conditions on board were good for the time, with regular nutritious food, plenty of exercise and an on-board hospital, and as a result there was a mortality of less than one percent.
