This chapter discusses – in the general problematics of languages in contact – Jewish languages and languages of the Diaspora. It intends to study from a comparative perspective especially the diachrony of Yiddish and Judeo-Spanish, two diasporic languages with similar developments and destinies. After a short presentation of the two languages, we examine successively: 1) the creation of Judaeo-languages in Diaspora, 2) the Diaspora versus migration, 3) the Judaeo-calque languages, 4) the common dynamics of Jewish languages, and 5) the diachrony of Jewish languages. The conclusion focuses on the successful innovations appearing in a Jewish language. It points out the important role of the Hebrew component (its direct and indirect influence), as well as the broad interlinguistic competence of Yiddish and Judaeo-Spanish speakers in the process of evolution of the languages considered.
