cobber

Etymology

Uncertain. Perhaps from Yiddish חבֿר (khaver, “friend, comrade”), from Hebrew חבר (ḥāḇēr, “friend”), possibly via Dutch gabber; alternately, perhaps from the British dialectal term cob (“take a liking to”), or a conflation of both. The suggestion that it is a self-referential collective term for convicts and immigrants who departed for Australian shores from the Irish port of Cobh seems chronologically unlikely.
