In the highly developed field of Persian-English lexicography a major gap exists in the area of colloquial, slang, and argot in Persian. To date, no Persian-English Dictionary of Persian colloquial slang, or argot language exists. This study fills this gap. The dissertation proper tells the story of the process and the fully covered /vāv/ section treats current slang and argot headwords and phrases including slang and secret languages of smugglers, drug dealers, prison inmates, the military and the teenagers. The dictionary which will be referred to as The Persian-English Dictionary of Slang (PEDS) presents a sample of 200 headwords beginning in the letter; [Arabic character] /vāv/. This study provides a sample of how the work is generated. The whole dictionary contains 15000+ headwords. / text
