Origin of shark

  • Origin unknown

    From American Heritage Dictionary of the English Language, 5th Edition

  • First attested in the 1560s, the word meaning 'scaleless fish' is of uncertain origin: it was apparently brought to England, with a specimen, by John Hawkins. The word may derive from the Yucatec Maya xoc, or it may be an application of the "scoundrel" sense (which derives from the German Schurke (“scoundrel")) to the fish; no explanation is agreed upon.

    From Wiktionary
