The story
Few phrases feel more British than this one. Yet the earliest known example comes from an American paper, the Massachusetts Spy, in June 1815. The writer said, “I kept a stiff upper lip,” about pressing on with a business deal. There it meant holding firm more than hiding tears.
The idea is plain to anyone who has fought back tears. When feelings rise, the mouth gives you away first. A lip held firm shows nothing.
By 1830, an Ohio newspaper was using the phrase for staying calm while anxious. Within a few years it was a familiar American expression.
Britain took it to heart. In the 1800s and early 1900s it became linked with the calm, unflappable manner prized in English schools and public life, and the American phrase came to sound like a British motto.
