Etymology: The French verb "déboucher" literally means "to unstop" or "to uncork." It combines "dé-," a prefix of removal or reversal, with "boucher," "to stop up," which comes from "bouche," "mouth," ultimately from the Latin "bucca," meaning cheek or mouth. The original sense was pulling the stopper from a bottle. From there the meaning shifted from opening a container to opening a passage. A river debouches when it flows out of a narrow valley onto a wider plain or into the sea, and troops debouch when they march out of a confined defile into open ground where they can spread out. The image is of something passing from a narrow neck into a wider space. English borrowed the word from French and kept this geographical and military sense. It is mostly found in descriptions of rivers, valleys, streets, and armies leaving confined spaces.
