Aronoff

Aronoff is a surname of Ashkenazi Jewish origin. It is a patronymic surname formed from the given name Aaron with a Slavic suffix such as -ov or -off, meaning "son of Aaron." The spelling Aronoff is one of several transliterations; other common forms include Aronov, Aronow, Aronowicz, and Aranoff. Variants reflect shifts in language, country of residence, and immigration-era orthography.

Historically, the surname likely arose in Eastern Europe where Jewish families used Slavic-style patronymics. After migration to North America, Israel, and other regions, different spellings emerged in response to local languages and administrative practices. As a result, bearers of the name are found in diverse professions and communities.

In onomastic use, Aronoff does not indicate a specific occupation or status; it primarily signals lineage from someone named Aaron. The name remains primarily a family surname, passed down through generations and sometimes altered as families moved across borders or through naturalization processes.
