Lishán Didán is a modern Jewish Aramaic language, often called Neo-Aramaic or Judeo-Aramaic. It was originally spoken in Iranian Azerbaijan, in the region of Lake Urmia, from Salmas to Mahabad. Most speakers now live in Israel.
The name Lishán Didán means 'our language'; other variations are Lishanán, 'our-language', and Lishanid Nash Didán, 'the language of our selves'. As this causes some confusion with similarly named dialects (Lishana Deni, Lishanid Noshan), scholarly sources tend simply to use a more descriptive name, like Persian Azerbaijani Jewish Neo-Aramaic.
To distinguish it from other dialects of Jewish Neo-Aramaic, Lishán Didán is sometimes called Lakhlokhi (literally 'to-you(f)-to-you(m)') or Galihalu ('mine-yours'), demonstrating different use of prepositions and pronominal suffixes. Lishán Didán is written in the Hebrew alphabet. Spelling tends to be highly phonetic, and elided letters are not written.
Various Neo-Aramaic dialects were spoken across a wide area from Lake Urmia to Lake Van (in Turkey), down to the plain of Mosul (in Iraq) and back across to Sanandaj (in Iran again).
