Etymology

The word traces back to Latin stagnare ("to form a pool of standing water"), derived from stagnum. Over time, it metaphorically expanded to describe inactivity or lack of progress in non-liquid contexts (e.g., ideas, economies). The core logic ties physical stillness to abstract inertia.

  3. Stagnating water can breed mosquitoes.
