Book excerpt: This manual provides a detailed presentation of the various Romance languages as they appear in texts written by Jews, mostly using the Hebrew alphabet. It gives a comprehensive overview of the Jews and the Romance languages in the Middle Ages (part I), as well as after the expulsions (part II). These sections are dedicated to Judaeo-Romance texts and linguistic traditions mainly from Italy, northern and southern France (French and Occitan), and the Iberian Peninsula (Catalan, Spanish, Portuguese). The Judaeo-Spanish varieties of the 20th and 21st centuries are discussed in a separate section (part III), due to the fact that Judaeo-Spanish can be considered an independent language. This section includes detailed descriptions of its phonetics/phonology, morphology, lexicon, and syntax.
