Etymology

Origin of heroism

1660–70; hero + -ism; compare French héroïsme

Explanation

When you think of heroism, you might think of great acts of bravery, such as rushing into burning buildings and facing danger in battle. Heroism consists of putting others first, even at your own peril. The noun heroism comes from the Greek hērōs, which referred to a demigod. As someone who shows great courage and valor is referred to as a hero, their actions are considered to be acts of heroism. 19th Century lawyer Robert Green Ingersoll said it well: “When the will defies fear, when duty throws the gauntlet down to fate, when honor scorns to compromise with death — that is heroism.”
