Did you know?

Fortitude comes from the Latin word fortis, meaning “strong,” and in English it has always been used primarily to describe strength of mind. For a time, the word was also used to mean “physical strength”; William Shakespeare used it that way in Henry VI, Part 1: “Coward of France! How much he wrongs his fame / Despairing of his own arm’s fortitude.” But despite use by the famous bard, that meaning languished and is now considered obsolete. Even the familiar phrase “intestinal fortitude” is just a humorous way to refer to someone’s courage or mental stamina, not the literal strength of their digestive system. (If you’re looking to describe a mighty gastrointestinal tract, we might suggest “iron stomach.”)
