Hydra
noun /ˈhaɪdrə/ — The many-headed monster that grows two heads for every one cut off — the problem that multiplies when fought.
Definition
In Greek mythology, a serpentine water monster with multiple heads, each of which regenerates two more when cut off; by extension, any complex problem that becomes more difficult when directly attacked.
Beyond the definition
The Hydra is mythology's most accurate metaphor for certain kinds of problems — bureaucracy, addiction, misinformation, entrenched inequality. The direct attack makes it worse. The Hydra requires a different strategy.
Origin & history
From Greek hydra — water serpent (from hydor: water). The water monster — Heracles killed it as his second labor, using fire to cauterize each stump. The strategy was to stop the regeneration, not just the cutting.
