Etymology

Origin of aqueduct

< Medieval Latin aquēductus < Latin aquae ductus a drawing off of water. See aqua, duct

Explanation

An aqueduct is a bridge-like system built to move water from one location to another. The ancient Romans were particularly famous for their aqueducts and some still stand today. The Romans didn't invent aqueducts, but they did help spawn the English word for one. Aqueduct comes from the Latin word aquæductus, which itself is from the roots aqua, meaning water, and ducere, meaning "to lead." Because of the root word aqua, there is a tendency to try to spell aqueduct with an A in place of the E, but now you'll know better.
