The term comes from a patron's manner of ordering alcohol without raising suspicion-a bartender would tell a patron to be quiet and speak easy.   The origin of the term speakeasy predates Prohibition by at least thirty years. Samuel Hudson, a newspaperman in the late 19th century, said he heard the term used in Pittsburgh in the 1880s by an old Irish woman who sold liquor without a license. She told her clients to speak easy if they wanted to buy some.
