Longest word in Farsi. کلمه بلندترین به فارسی What is the longest word in Farsi? I want an official one if possible rather than just what the longest word you can think of is. For example in English, it is common knowledge that the longest word (to a degree) is antidisestablishmentarianism. This word is never used in everyday language though. If you don't know an official one then I would still like to hear your suggestions. mersi
