Definitions
small tubular solitary freshwater hydrozoan polyp
Word origin
After the Hydra, from Greek mythology, which grew two new heads every time one of its heads was cut off. The biology sense alludes to the budding method of asexual reproduction that the hydra practices, similar to growing new heads. The figurative sense refers to how the creature could not be killed by a swift, decisive solution (in contrast to a Gordian knot).
Used in a sentence
“At night I lie dry-eyed on my little bed and turn my head to and fro to catch sight of one little star by one little star along the tail of Hydra, and think you are alive, you survive. Is this not what you wanted?”
