'What is more' is a phrase used to introduce an additional point or piece of information that supports or adds to the previous statement. It’s very similar in meaning to 'moreover' or 'furthermore.' It's used to emphasize that what follows is important and relevant to the ongoing discussion. Think of it as adding an extra topping to a pizza, making it even better. It helps to strengthen an argument or provide additional context to a situation. It signals that there's more to the story than what has already been presented.
