What does downspout mean?
A downspout is the vertical pipe that carries rainwater from a building's roof gutters down to the ground or to a drainage system. It is a standard term in American English for what British speakers more often call a downpipe or drainpipe. Downspouts are essential parts of any roof-drainage setup: they channel water safely away from walls and foundations, preventing erosion, damp basements, and structural damage. The word appears most often in practical contexts — home maintenance, construction, landscaping — as in clearing a clogged downspout or adding a downspout extension to redirect runoff. Though humble in appearance, the downspout plays a critical role in protecting a building, making it a useful and precise term for anyone discussing roofing, plumbing, or property care.

The word 'eavesdropping' literally comes from standing under the eaves where water drips — the same drainage world that gave us 'downspout'.
