The Vietnamese phrase "hơn nữa" translates to "moreover" or "furthermore" in English. It is used to add more information or to emphasize a point that supports what has already been said.
You can use "hơn nữa" when you want to introduce an additional idea or fact that enhances your previous statement. It's often used in both spoken and written Vietnamese, especially in formal contexts or when making arguments.
In more formal writing or speeches, "hơn nữa" can help to structure your arguments clearly. It indicates that what follows is not only related but also significant in supporting the argument.
While "hơn nữa" primarily means "moreover," it can also imply "what's more" or "besides" in conversation, depending on the context.
