watershed 分水岭

water,水，shed,分开。

watershed (n.): "line separating waters flowing into different rivers," 1803, from water (n.1) + shed in a topographical sense of "ridge of high ground between two valleys or lower ground, a divide," perhaps from shed (v.) in its extended noun sense of "the part of the hair of the head" (14c.). Perhaps a loan-translation of German Wasser-scheide. Figurative sense is attested from 1878. Meaning "ground of a river system" is from 1878.
