 The Jews of Baghdad are a largely indigenous population and they also preserve the pre-Mongol invasion dialect of Baghdad in its Jewish form, which is similar but a bit different from the general pre-Mongol Baghdadi dialect due to the linguistic influences of Hebrew and Judeo-Babylonian Aramaic, instead of the general Babylonian Aramaic that existed before the Islamic invasion.As with other respective religious and ethnic communities coexisting in Baghdad, the Jewish community had almost exclusively spoken as well as written in their distinctive dialect, largely drawing their linguistic influences from Hebrew and Judeo-Aramaic and even non-linguistic influences from languages such as Sumerian, Akkadian, Persian and Turkish.Simultaneous fluency and literacy in the Arabic used by the dominant Muslim communities had also been commonplace.
