Origin of hydra

  • Middle English Idra from Latin Hydra from Greek Hudrā Hydra, a water serpent wed-1 in Indo-European roots

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

  • New Latin Hydra genus name from Latin Hydra Hydra Hydra

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

  • After the Hydra, from Greek mythology, which grew two new heads every time one of its heads was cut off. The first sense alludes to the budding method of asexual reproduction that the hydra practices, similar to growing new heads. The second sense refers to how the creature could not be killed by a swift, decisive solution (in contrast to a Gordian knot).

    From Wiktionary
