↑R.N Frye, "IRAN v. PEOPLES OF IRAN" in Encycloapedia Iranica. "In the following discussion of “Iranian peoples,” the term “Iranian” may be understood in two ways. It is, first of all, a linguistic classification, intended to designate any society which inherited or adopted, and transmitted, an Iranian language. The set of Iranian-speaking peoples is thus considered a kind of unity, in spite of their distinct lineage identities plus all the factors which may have further differentiated any one group’s sense of self."
↑R. N. Fyre, "IRAN v. PEOPLES OF IRAN" in Encycloapedia Iranica, "The largest group of people in present-day Iran are Persians (*q.v.) who speak dialects of the language called Fārsi in Persian, since it was primarily the tongue of the people of Fārs."
