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.
The Memorandum
Length of words, like everything else in Ptydepe, is determined scientifically. The vocabulary of Ptydepe uses entropy encoding: shorter words have more common meanings. Therefore, the shortest word in Ptydepe, "gh", corresponds to what is so far known to be the most general term in natural language, "whatever". (The longest word in Ptydepe, which contains 319 letters, is the word for "wombat" in an English translation. However in the Czech original it is a name for a nonexistent member of the genus Apus, rorýs říční.) Theoretically an even shorter word than "gh" exists in Ptydepe, namely "f", but it has no meaning assigned and is held in reserve in case a more general term than "whatever" is discovered.
