Here's an example:
- Chocolate lovers rejoice!
- Chocolate lovers, rejoice!
To my understanding, the first one says that chocolate lovers are rejoicing and in the second one, we are asking the chocolate lovers to rejoice.
Am I correct? Or is it fine to use both 1 and 2 interchangeably?
Also, if am wrong about the second one, then how do you convey to chocolate lovers that they should rejoice?
