According to the ISO-639-3, Farsi is a macro language. From my position it is a clear case as the standard says so, it is likely to be so. Farsi is divided in two, Western Farsi and Eastern Farsi. Western Farsi is spoken primarily in Iran and Eastern Farsi in Afghanistan and Pakistan.
The problem I have is that several people I respect, independently inform me that in their opinion this division is wrong. Farsi is said to be understood by all. Raising this question is for me about something practical. In this case it is about a request for a fa.wikinews.org.
Let me be clear, I am all in favour of such a project but I do not want to continue an ambiguity about the language. The practical question is, to what extend is it justified to consider Farsi and Dari as separate languages. When they are indeed to be considered separate languages, how different are they. Can it be compared in a similar way as South African and Dutch?
