Judeo–Kashani
There are very few native speakers, most of whom are elderly and are located not in Kashan. The remaining speakers of Judeo–Kashani live in Jewish Kashani communities in North America and Israel. The language is similar to Judeo–Hamedani and Judeo–Isfahani. It has not appeared much in Jewish literature from the area, with most notable Jewish Kashani publications being published in either Judeo-Persian or Persian.
