Persian fārsī, of Persia, alteration (influenced by Arabic Fāris, Persia) of pārsī, from Middle Persian pārsīg.(American Heritage® Dictionary of the English Language, Fourth Edition)
Apparently first used widely in English in the late 1960s or early 1970s. From Persian فارسی (fârsi), from Fars, the Arabic name for the province of Persis (“Pars”) in southwestern Iran (Arabic lacks the sound ‘p’). That name was adopted by the Arabs and Persians to refer to the Persian language after the Islamic invasions of the 7th century. (Wiktionary)
