An Etymological Dictionary of the German Language/Annotated/Oblate

by Friedrich Kluge

Oblate, feminine, from the equivalent Middle High German oblât, oblâte, feminine and neuter, ‘the Host, wafer’; from Latin oblâta (from offerre, which was adopted as opfern), whence also the equivalent Anglo-Saxon ofelête; Middle English oblê is formed, however, from Old French oublee, whence Modern French oublie. See Opfer.
