Using clear and exact language is very important in communication and argumentation. When we define words correctly, we help others understand our ideas better and avoid confusion. There are different types of definitions, like stipulative (a new meaning we give to a word), precising (to make the meaning more exact), and persuasive (to influence someone’s opinion). We should also be careful with emotive language, because it can make people feel strong emotions and stop thinking clearly. Good arguments need language that is clear, fair, and easy to understand.
