The Hebraization of surnames (also Hebraicization) (Hebrew: עברות‬, Ivrut, "Hebraization") is the act of adopting a Hebrew surname in exchange for their diaspora names. … Names ending with -berg, -stein or -man are often thought of as Jewish, but are of German origin, while suffixes such as -sky and -vitz are Slavic.

After the Israeli Declaration of Independence, there was still the attitude that the hebraization of family names should continue, in order to get rid of names with a diaspora sound.[4] Hebraization of names became a typical part of the integration process for new immigrants among Ashkenazi Jews, but also among Sephardi and Mizrahi Jewish immigrants from Arab and Muslim lands; Sephardi and Mizrahi children were typically given new Hebrew names in school, often without permission from their parents
