It must have been television newscasters - second only to sports radio in mangling the language - that one day decided that people no longer disappear. They “go missing.” Go missing? How can that be? To disappear is to cease to appear. To vanish. Isn’t that the case when somebody, uh . . . disappears?
Missing does indeed, mean absent, lost, not present. So, to say that Charlie is missing is fine. But to say Charlie has GONE missing or went missing? How does that make sense?
