A word derived from or related to another word; also, the form in one language for a word in another, as in the English canal for the Latin canalis.
Sidelight: In 1877, the Italian astronomer, Schiaparelli, charted a number of linear surface features he observed on the planet Mars. He thought them to be natural waterways formed by erosion due the action of a flowing liquid and termed them canali, Italian for "channels." Translated into English as "canals," this led to a popular conception of artificial irrigation canals constructed by Martian inhabitants to carry water from the polar caps to the rest of the planet, an idea which persisted until finally disproved by the Mariner spacecraft flights in the 1970's.
