A lot of people don't have a lot of metacognition. They really feel the way they think about things is the way everybody thinks about things because they're in their own heads; so getting metacognition is a little harder than just knowing what it is. Because that means you can instinctively understand that when you use a word, the person that's listening to you may not have the same experience of that word, or be coming from a different context or different power position or different anything. They might be coming from a different event that totally stressed them out as you're having a conversation.
