Etymology: The adjective "doolally," meaning eccentric, mad, or slightly crazy, originated in British India during the colonial period. The word derives from Deolali (also spelled Deoghali), a town in Maharashtra in western India that housed a major British military cantonment and transit camp. Soldiers stationed there or passing through the camp were often afflicted with a condition of mental instability, apparently brought on by the heat, boredom, and the stress of awaiting deployment or repatriation. The camp became notorious enough that its name entered the vocabulary of British servicemen as a synonym for mental disturbance. The word likely entered English usage in the late 19th or early 20th century, gaining particular currency among British military personnel who had served in India. As the British Empire contracted and India gained independence, the word persisted in British English, though it became somewhat dated and colloquial. The original geographical reference faded from common awareness, and "doolally" became simply a slang term for madness or eccentricity, often used in the phrase "go doolally." The connection to the Indian town is now largely forgotten outside of etymological circles, making it one of those words whose origin story is far more interesting than its current users realize. The term has remained primarily British in usage and carries a somewhat dated, humorous tone rather than any clinical or offensive connotation.
