Etymology

Origin of canal

First recorded in 1400–50; late Middle English: “waterpipe, tubular passage,” from Latin canālis, perhaps equivalent to can(na) “reed, pipe” ( see cane) + -ālis -al ¹; canal def. 5 a mistranslation of Italian canali “channels,” the term used by G. V. Schiaparelli

Explanation

A canal is a long, man-made strip of water used for irrigation or boat access to a bigger body of water, like the famous Erie Canal, which connects the Hudson River to Lake Erie. Canal is related to the word channel, and all its different shades of meaning have to do with tunnel shaped spaces that carry liquid from one place to another. Besides man-made irrigation canals, canals that connect boat docks to rivers and oceans, or street-like canals in boat cities like Amsterdam, there are canals in your body, like your nasal canal, or the birth canal you came out of. It's also a verb meaning "to dig a canal."
