The Devil's Dictionary is a satirical dictionary written by American Civil War soldier, journalist, and writer Ambrose Bierce consisting of common words followed by humorous and satirical definitions.
The lexicon was written over three decades as a series of installments for magazines and newspapers. Bierce's witty definitions were imitated and plagiarized for years before he gathered them into books, first as The Cynic's Word Book in 1906 and then in a more complete version as The Devil's Dictionary in 1911.
The Devil's Dictionary was begun in a weekly paper in 1881, and was continued in a desultory way at long intervals until 1906. In that year a large part of it was published in covers with the title The Cynic's Word Book, a name which the author had not the power to reject or happiness to approve.
