Is Pseudopseudohypoparathyroidism the longest word ever twittered?
Well… there’s one for the google bots to feast on… Pseudopseudohypoparathyroidism is the longest non-coined word in the English dictionary (according to Wikipedia amongst others), however, there are some longer, technical words, including Lopadotemachoselachogaleokranioleipsanodrimhypotrimmatosilphioparaomelitokatakechymenokichlepikossyphophattoperisteralektryonoptekephalliokigklopeleiolagoiosiraiobaphetraganopterygon - which is apparently fictional food dish mentioned in an Ancient Greek comedy by Aristophanes…
Another possibility is Pneumonoultramicroscopicsilicovolcanoconiosis, which is a word alleged to mean ‘a lung disease caused by the inhalation of very fine silica dust, causing inflammation in the lungs.
We have tweated Pseudopseudohypoparathyroidism and are awaiting someone to go for something bigger:)
