Odium is a heavy, formal word for the strong dislike that a lot of people share toward someone — or toward a law, a plan, a group — because of something that has been done. It is not the private feeling you have when you simply do not like a person. Friends do not tell you they feel odium. It is public: a leader can fall into odium; a company can earn the odium of its customers; a cruel rule can attract odium. The word sits on the person like a dark cloud that many people help to hold up. There is also an older, more inward use, where odium is the hatred itself, not only the bad name that follows it. Even there it sounds Latin and a little old, and that is how it is meant to sound. Though actually, almost nobody says this in daily talk. People say everyone hates him, or he is very unpopular, or they all turned against her. You will meet odium in newspapers, history books, and careful essays. Younger speakers almost never reach for it.
