Judaeo-Catalan (Hebrew: קטלאנית יהודית; Catalan: judeocatalà, IPA: [ʒuˌðewkətəˈla]), also called Catalanic or Qatalanit (Hebrew: קאטאלנית; Catalan: catalànic or qatalanit), was a presumed Jewish language spoken by the Jews in Northern Catalonia and what is today Northeastern Spain, especially in Catalonia, Valencia and the Balearic Islands.
This would be the case of the Jews living in Old Catalonia, stretching between Perpignan and Barcelona, linked with Occitania at least until the battle of Muret in 1213.
However, in western and southern Catalonia, Judaeo-Catalan should have been quite distinct from Judaeo-Provençal, mostly as a result of the Moorish conquest of Iberia.
The golden age of Judaeo-Catalan is supposed to have been between the early 12th century and 1492, when the Jews were expelled from Spain by Alhambra Decree.
[3] In one of the few investigations on the subject, Feliu and Ferrer (2011) analyzed a set of notarial texts of 1443, and concluded that their analysis "allows us to sign the death certificate of a linguistic ghost – the supposed 'Judeo-Catalan dialect' that never was".
