Robert Hartwell Fiske's Dictionary of Unendurable English: A Compendium of Mistakes in Grammar, Usage, and Spelling with commentary on lexicographers and linguists.

Today's popular dictionaries often fail to define words correctly or to distinguish between them; some dictionaries even maintain that one word means the same as another simply because people who do not know the correct meanings of the words confuse them. Robert Hartwell Fiske's Dictionary of Unendurable English -- a supplement to whatever dictionary you own or use -- is an attempt to combat this nonsense, to return meaning and distinction to the words we use.
