Had Dickens owned a copy of The King's English he would not have written 'your great ability and trustfulness'; he would have recognized the malapropism and realized that the context demanded trustworthiness. In this classic reference book the Fowler brothers illustrate by examples all the blunders of English usage that are commonly made, and guide the reader to improved expression and style.
-- The essential guide to written English
-- Examples of commonly-made grammatical blunders taken from famous authors and newspapers, eg Thackeray, Ruskin, De Quincey, The Times, The Spectator
-- The ideal companion to Fowler's Modern English Usage
