Language is important in arguments because it helps us share ideas clearly. If we use vague or confusing words, people may not understand us. Emotional words like “terrible” or “heroic” can make others feel strong emotions, but they do not always help the argument. We also need to watch out for mistakes in arguments, called fallacies. For example, attacking the person (ad hominem) or saying one small thing will cause something big without proof (slippery slope). Learning to see these mistakes helps us think better and make fair decisions.
