What is "judaeo-catalan"

Judæo-Catalan (; , ), also called Catalanic or Qatalanit (; or ), was a Jewish language spoken by the Jewish communities in northeastern Spain, especially in Catalonia, Valencia, and the Balearic Islands.

Linguistically, it shared many features in common with early Judæo-Provençal, although historically, ethnically, and politically, the Judæo-Catalan-speaking community was long distinct from the Judæo-Provençal-speaking community, mostly as a result of the Moorish occupation of Iberia. The golden age of Judæo-Catalan was in the period between the early 12th century and 1491, when the Jews were expelled from Catalonia and Valencia (see Alhambra decree).
