Origin of fortitude
First recorded 1350–1400; Middle English, from Latin fortitūdō “strength, firmness, courage,” equivalent to forti(s) “strong” + -tūdō noun suffix ( -tude )
Explanation
Fortitude refers to strength in the face of adversity or difficulty. Eating fried worms might require a lot of intestinal fortitude. When someone has fortitude it means that they have emotional power or reserves and the ability to withstand adversity. People who have fortitude are described in an admiring way for their courage and this word comes from the Latin word fortitudo, meaning "strength." Jacueline Bisset, someone who knows about beauty, said, "Character contributes to beauty. It fortifies a woman as her youth fades. A mode of conduct, a standard of courage, discipline, fortitude and integrity can do a great deal to make a woman beautiful."
