 While the initial leaders of the process insisted they were only continuing "from the place where Hebrew's vitality was ended", what was created represented a broader basis of language acceptance; it includes characteristics derived from all periods of Hebrew language, as well as from the non-Hebrew languages used by the long-established European, North African, and Middle Eastern Jewish communities, with Yiddish (the European variant) being predominant.Historical records testify to the existence of Hebrew from the 10th century BCE to the late Second Temple period (lasting to c. 70 CE), after which the language developed into Mishnaic Hebrew.
