hamburger: [19] As its inherent beefiness amply demonstrates, the hamburger has nothing to do with ham. It originated in the German city and port of Hamburg. The fashioning of conveniently sized patties was a common way of dealing with minced beef in northern Europe and the Baltic in the 19th century, and it appears that German sailors or emigrants took the delicacy across the Atlantic with them to America.

There it was called a Hamburg steak or, using the German adjectival form, a Hamburger steak. That term is first recorded in the late 1880s, and by the first decade of the 20th century the steak had been dropped. By the 1930s the hamburger had become an American fast-food staple, and products similar in concept but with different ingredients inspired variations on its name: beefburger, cheeseburger, steakburger, and so on; and by the end of the decade plain burger was well established in the language.
