A new version of the Thesaurus of Persian Words and Phrases (farhang-e teyfi, version 3.0, summer 2012) is now available for downloading at
The new version is the result of four years of work after the draft of print version of the book published in 2009 and includes additions and amendments increasing the coverage of the book by 25%.
The hardback version was printed by Hermes Publishers, Tehran, 2009; “Farhang-e Teyfi”;
Farhang-e Teyfi is based on Roget’s model of English Thesaurus which lists words in one semantic category irrespective of their grammatical / syntactic constituent type such as noun, verb, adjective and adverb – i.e. all these are grouped together under one category (of meaning).
My next project is to produce an Android app of Farsi synonyms.
