Gryffindors are brave, loyal, and brash. Since Harry is a Gryffindor, they are the most glorified in the series, but each House has equal pluses and minuses. Joan of Arc is a good example of a Gryffindor!
Hufflepuffs are kind, loyal, fair, and hardworking. They are often construed as “the rest”, but they are in fact an important House of their own. Bono could be a Hufflepuff!
Ravenclaws value wit, learning, and brains. They are smart, often analytical and enjoy learning, but can sometimes have their heads in the clouds. Albert Einstein is an obvious Ravenclaw!
Slytherins are ambitious, cunning, mischevious, and loyal. Although often depicted as “evil”, this is really only their ambition shining through. Donald Trump is an excellent example of a would-be Slytherin!
