The Devil's Dictionary is a satirical dictionary written by Ambrose Bierce. It consists of ordinary words followed by witty and satirical characterizations.

Ambrose Bierce, born on June 24, 1842, in Meigs County, Ohio, stands as a prominent figure in American literature renowned for his sardonic wit and scornful view of human nature. An editorialist, journalist, short-story writer, and satirist, Bierce is best known for 'The Devil's Dictionary' (1911), a lexicon that wryly redefines common English words, casting a cynical glance at social, political, and religious conventions. Serving in the Union Army during the American Civil War, his experience at the forefront of conflict left an indelible mark, permeating his literary works with themes of death and the macabre. The war's visceral impact was particularly evident in Bierce's short stories, such as 'An Occurrence at Owl Creek Bridge' and 'Chickamauga,' both of which are hailed for their realism and psychological depth. His acerbic style and dark humor influenced the development of the American short story, placing him alongside contemporaries like Edgar Allan Poe and Mark Twain. Bierce's disappearance in Mexico in 1914 only compounds the enigma of his complex character. As an author committed to exploring the bleak truths of the human condition, Bierce's contributions endure in the pantheon of American letters, his writings continuing to fascinate for their blend of pessimism and incisive critique.
