Origo (or pragmatics) is all about how words are used in different contexts and how the meaning of words can change. For example, if you said, "I'm thirsty," it would mean one thing if you're in a classroom and another if you're in a restaurant. This is because when we are using words, the meaning can change depending on the situation. Origo helps us understand how to use words in the right way so we don't get confused or misunderstand other people.
