In this episode, The old saying KISS (Keep it Super Simple) is appropriate here. Language can be very simple. It is best used with the fewest words needed to completely convey a message. It is also important to understand that communication is the goal and nothing else.
If you use words or structure your listener does not know, you fail in your objective. Language is not intended to obfuscate but instead to illuminate. Also, your tonality and pacing are important in creating understanding. Learning to use language to be clear and complete is a powerful skill. Storytelling also uses simple language and is a perfect example of simple yet clear messaging.
