The Hutchinson Dictionary of Difficult Words John Ayto
Concentrating on the words which cause most difficulty for the average English user, this dictionary provides clear, concise definitions with the emphasis on problem points - spelling, pronunciation, disputed usage and confused meanings. And, for quiz buffs, a sprinkling of less-common words is included. This new edition, entirely revised and reset, and including over 1500 entries, covers such areas of language as spelling, pronunciation, usage and uncommon words.
