frequent debate about the extent of the linguistic independence of Yiddish from the languages that it absorbed. There has been periodic assertion that Yiddish is a dialect of German, or even "just broken German, more of a linguistic mishmash than a true language". Even when recognized as an autonomous language, it has sometimes been referred to as Judeo-German, along the lines of other Jewish languages like Judeo-Persian, Judeo-Spanish or Judeo-French. A widely cited summary of attitudes in the 1930s was published by Max Weinreich, quoting a remark by an auditor of one of his lectures: ( — "A language is a dialect with an army and navy"). Israel and Zionism The national language of Israel is modern Hebrew. The debate in Zionist circles over the use of Yiddish in Israel and in the diaspora in preference to Hebrew also reflected the tensions between religious and secular Jewish lifestyles. Many secular Zionists wanted Hebrew as the sole language of Jews, to contribute to a national cohesive identity. Traditionally religious Jews, on the other hand, preferred use of Yiddish, viewing Hebrew as a respected holy language reserved for prayer and religious study.

This conflict also reflected the opposing views among secular Jews worldwide, one side seeing Hebrew (and Zionism) and the other Yiddish (and Internationalism) as the means of defining Jewish nationalism. In the 1920s and 1930s, , "Battalion for the Defence of the Language", whose motto was " ", that is, "Hebrew [i.e. Jew], speak Hebrew!", used to tear down signs written in "foreign" languages and disturb Yiddish theatre gatherings. However, according to linguist Ghil'ad Zuckermann, the members of this group in particular, and the Hebrew revival in general, did not succeed in uprooting Yiddish patterns (as well as the patterns of other European languages Jewish immigrants spoke) within what he calls "Israeli", i.e. Modern Hebrew. Zuckermann believes that "Israeli does include numerous Hebrew elements resulting from a conscious revival but also numerous pervasive linguistic features deriving from a subconscious survival of the revivalists’ mother tongues, e.g. Yiddish." After the founding of the State of Israel, a massive wave of Jewish immigrants from Arab countries arrived. In short order, these Mizrahi Jews and their descendants would account for nearly half
