Here are some examples of how it can be used:
* "This is nothing more or less than a simple misunderstanding." This means that there is no hidden agenda or complex reason behind the situation, it's simply a misunderstanding.
* "He's nothing more or less than a good friend." This means that he is just a friend, not a romantic partner, business partner, or anything else.
* "The answer is nothing more or less than the sum of the numbers." This means that the answer is exactly the result of adding the numbers together, and there are no tricks or hidden steps involved.
In essence, "nothing more or less" is a way to emphasize straightforwardness and clarity. It ensures that the listener understands the meaning without any ambiguity or room for interpretation.
