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."

A mode of conduct, a standard of courage, discipline, fortitude and integrity can do a great deal to make a woman beautiful."
