"In the Kashan area there is a high degree of use of Persian in all but the most intimate communication (cf. Majidi, 1975, passim). In the past few decades, rural Kashan has rapidly been shifting to Persian. Most villages have already been partly or entirely persianized, and practically all the native speakers are bilingual (see Borjian, 2009)." (p.7)

Persian is the primary means of communication.
