What language did Jews speak in Spain?

The main language spoken by Jews in Spain was Judeo-Spanish, also known as Ladino. It is a Romance language that developed among the Jewish communities in Spain during the Middle Ages. Judeo-Spanish is based on Old Spanish, but it has also incorporated elements from Hebrew and Aramaic. It was the main language of Spanish Jews until the 15th century, when they were expelled from Spain. Judeo-Spanish is still spoken by some Sephardic Jewish communities around the world, particularly in Turkey, Greece, the Balkans, and North Africa.
