Other forms: eristics
If you love to argue, you're eristic. Being eristic is a fairly common quality for a debater to have.
Eristic describes things that have to do with an argument, or simply the tendency to debate, especially when someone loves to win an argument and values that more highly than arriving at the truth. The person doing the arguing can also be called an eristic: "It makes me mad when that eristic wins his debates with his false arguments." The Greek root word is eris, "strife or discord."
