↑There are different opinions about appellation of Forg. One of them which is more common is the belief that Forg was commonly pronounced Fork among people. In Dehkhoda Dictionary as quoted from Encyclopedia, it has been explicitly mentioned that Fork is the name of the ancestor of a family in Iran, and is an Iranian name. The other version is that Fork was the name of the daughter of "Ryan Konouj", who was an Indian kings. Fork was the wife of Bahram Gour (as stated in Borhan) and/or perhaps it has been taken from Persian "Pour" meaning "son". Some others attribute Fork to the founder of this village, i.e. Mozafar Keyghobad, and based on an inscription on which the year of 307 is written, they infer that as the founder of this village was initially "Pour Keyghobad", it was firstly called "Pourg", and then was changed to Fork and then to Forg by lapse of time.
