“SIR – I have noticed that “mercurial” has become a rather overused word to describe Nicolas Sarkozy in The Economist. It has been used no less than ten times since March this year alone, most recently in your October 22nd issue (“Sauce Hollandaise”). Although it aptly epitomises Mr Sarkozy, perhaps you will permit me to suggest some alternatives: capricious, changeable, erratic, expansive, fickle, impulsive, inconstant, irregular, irrepressible, lubricious, spirited, unpredictable, unstable, variable, volatile.”—A reader speaks his mind.
