köken: From Middle High German kelnære, from Old High German kelnere, from Medieval Latin cellenarius (“(wine) cellar administrator”), from Late Latin cellārium (“pantry”), with influence of Keller, itself ultimately from the same Latin source.
köken: Borrowed from Medieval Latin camarārius (Late Latin camerārius (“chamberlain”)), related to cámara (“room”). Compare Catalan cambrer and Italian cameriere.
köken: From Middle Low German küper, from Middle Low German kupe (“cask”). Compare English cooper, Dutch kuiper (“cooper”), Danish kyper (“cellarer”), German Küfer (“cellarman”). See also German Kellner (“waiter”).
köken: palvella (“to serve”) + -in (instrumental noun suffix); evidently a calque of English server, although using the instrumental noun suffix -in instead of the more literal (and less fitting) -ja (“-er”, agent noun suffix).
köken: pince (“cellar”) + -ér (occupation suffix). Created during the Hungarian language reform, which took place in the 18th–19th centuries, patterned after the German Kellner (“waiter”), itself based on the Medieval Latin cellenārius (“cellarman”). Compare other occupations with the -ár / -ér suffix: kádár (“cooper”), böllér (“butcher, pig-slaugherman”), pintér (“cooper”).
