I have long been puzzled by the usage of 'verb + not'. For example, Kennedy said, "... my fellow Americans, ask not what your country can do for you, ask what you can do for your country." The Bible ...

What's the difference between an inverted question and a normal-order question? Why invert? Is there a reason or a benefit? I love you? Do I love you?
