The book contains a synchronic description of the phonetic structure of Warsaw Yiddish. This takes the form of a linguistic analysis of spoken Yiddish on the basis of interviews with the last remaining speakers of this Warsaw dialect, which is now on the verge of extinction. The recorded material is given in the second part of the book in a number of versions: phonetic/prosodic, Yiddish, German and Polish. Alongside a detailed description of the vowel and consonant systems there is also a taxonomy of sentence-phonetic phenomena representing an entirely new departure in the field of Yiddish studies. In addition typological issues posed by Yiddish morphosyntax are addressed from the perspective of the intermediate status of Yiddish between the Germanic and Slavonic language families.
