==Esperanto== 

 There are several problems with the long compound word in Esperanto (komencopaleontologiokonservatoriaĉestriĝontajn). First of all, in Esperanto only roots and suffixes are used in compounding, while suffixes normally appear only at the end of the whole compound word. Thus we should have komenc-paleontologi-kons. Furthermore, the first part komenc(o)- is not normally used in compounds to mean "about to begin to". Beginning an action is usually represented by the prefix ek-, while to me komenc- means rather "in the beginning", "originally". 

 Another remark, on the sentence "such clusters are not considered good style". Compound words, or words with several affixes, are perfectly normal in Esperanto and indeed form the backbone of adaptibility for the language. Certainly 46-letter words are extremely unusual, but words longer than 12 letters are common. According to the Esperanto Wikipedia, the longest words that actually occur in the Tekstaro corpus are 23 letters long (ŝtatimpostadministradon and interlingvistikŝatantoj). I would very much like to see a source for the 46-letter word.
