What is a hero? My World Book dictionary defines a hero as “a man or boy admired for his bravery, great deeds, or noble qualities” but I think it’s not quite as simple as that — and it’s certainly a topic worth discussing. Today’s subject was suggested by a reader who said that a teacher friend of his was having difficulty finding material on heroes. Loving a challenge, I got right to work. I hope these sites will stimulate discussion and help you form your own definition of the word.
