For a significant portion of its history, Yiddish was the primary spoken language of the Ashkenazi Jews and once spanned a broad dialect continuum from Western Yiddish to three major groups within Eastern Yiddish, namely Litvish, Poylish and Ukrainish. Eastern and Western Yiddish are most markedly distinguished by the extensive inclusion of words of Slavic origin in the Eastern dialects. While Western Yiddish has few remaining speakers, Eastern dialects remain in wide use.
