Etymology

The word "drainage" combines "drain," derived from Old English drēahnian (to draw off liquid), with the suffix "-age," borrowed from Old French -age, denoting an action or its result. The root "drain" originally referred to the gradual removal of water, while "-age" systematized the concept into a process or outcome. Over time, "drainage" expanded from agricultural contexts (e.g., field drainage) to medical and urban infrastructure uses, reflecting its core logic of controlled liquid removal.

  3. Farmers improved crop yields by installing a subsurface drainage system.

  4. The city’s outdated drainage infrastructure struggles with monsoon seasons.
