Banach (pronounced [ˈbanaç] in German, [ˈbanax] in Slavic Languages, and /ˈbɛnɛk/ or /ˈbɒnɒk/[1] in English) is a Jewish surname[2] of Ashkenazi origin[3] believed to stem from the translation of the phrase "son of man", combining the Hebrew word ben ("son of") and Arameic nasha ("man"). Worth mentioning is how the Sephardic surname Banache presents a variant with the -ache alternative ultima, common in other Jewish surnames such as Farache,[4] Ayache, Nakache, Harache[5] or Marrache.


Banach means bastard in Old Polish and in some Old Polish dialects someone clumsy[6]. As of 2023 about 67529 Polish people carried this surname in forms: Banach, Banachewicz, Banachowicz, Banachowski, Banasz, Banaszyński, Banaszyk, Banaszuk, Banaszewski, Banaszek, Banaszak, Banasiak, Banaśkiewicz, ... [7]. All those forms are connected with Banach, as in Polish -ch suffix often trangressed to -sz or -ś/-si. Additional -wicz is a patronymic suffix. Late (XVII century+) -ski/-cki/-dzki suffixes are connected with historical (middle ages) -ski reflecting Polish z (from) nobiliary particle (e.g. Jan z Tarnowa was equally known by the name Jan Tarnowski).
