Amcho

Amcho or amcha, also transliterated as amkho or amkha (Hebrew: עמכו, romanized: ʾamkho, lit. 'one's people', plural: עמכות ʾamkhot; Yiddish: אמכא, romanized: amkha, lit. 'common people'), is an idiomatic term that refers to the common people, especially Jews, as opposed to the elite. It was commonly used among Jews in Europe, especially during the Holocaust, as a means of identification.

During World War II, when Jewish refugees were seeking family and friends during genocide, the term amcho served as a shibboleth to identify fellow Jews. In modern times, various survivors recall using it to determine if strangers were Jewish and potentially find allies or assistance.

The term originates from Hebrew עמך (amkhá) meaning "one's nation" or "people", through Yiddish עמך (ámkho) meaning "common people," essentially "Jews".
