In the sense “extract, preparation”, from Latin valentia (“strength, capacity”) (1425). The now-current sense of “combining capacity (of an atom)” is from German Valenz (1884), from the same Latin word. The linguistic definition was formed in analogy to its use in chemistry. The sense “one-dimensional value” used in psychology is also from German Valenz (1935).
