In this important book, Lesley Jeffries introduces a phenomenon which has not been given the attention it deserves - the contextual construction of oppositional meaning. These are opposites not recognisable as such out of context but that are clearly set up this way in the text concerned.
The significance of oppositional meaning is well-known, and has been discussed by scholars for millennia, from Philosophy to Politics. But the main emphasis has always been on the conventional opposite: the opposite recognised by lexical semantics.
