I have a question about the usage of "break" and "break up". Suppose the context is police dealing terrorist organization.
- Police broke several major terrorist organizations.
- Police broke up several major terrorist organizations.
Dictionaries seem to suggest that both "break" and "break up" are okay in this context. But what do native speakers think? Is either one better?
Also, in a separate context of a meeting:
- The meeting broke at noon.
- The meeting broke up at noon.
Are both sentences 3 & 4 the same? Or is one of them wrong?
