Sephardi Jews, therefore, encompass Jews descended from those Jews who left the Iberian Peninsula as Jews by the expiration of the respective decreed deadlines.
This group is further divided between those who fled south to North Africa, as opposed to those who fled eastwards to the Balkans, West Asia and beyond.
Haketia (also known as "Tetouani" in Algeria), an Arabic-influenced Judaeo-Spanish variety also derived from Old Spanish, with numerous Hebrew and Aramaic terms was spoken by North African Sephardim, taken with them in the 15th century after the expulsion from Spain in 1492.
The main feature of this dialect is the heavy influence of the Jebli Arabic dialect of northern Morocco.
In its most basic form, this broad religious definition of a Sephardi refers to any Jew, of any ethnic background, who follows the customs and traditions of Sepharad.
Indeed, a further number of those Jews who had not yet joined the converso community finally chose to convert and avoid expulsion as a result of the edict.
As a result of the Alhambra decree and persecution during the prior century, between 200,000 and 250,000 Jews converted to Catholicism and between one third and one half of Spain's remaining 100,000 non-converted Jews chose exile, with an indeterminate number returning to Spain in the years following the expulsion.
Historically, the vernacular languages of Sephardim and their descendants have been variants of either Spanish or Portuguese, though other tongues had been adopted and adapted throughout their history.
The historical forms of Spanish or Portuguese that differing Sephardic communities spoke communally was determined by the date of their departure from Iberia, and their condition of departure as Jews or New Christians.
