The following sentences appear to be grammatically correct but I have a question regarding the last sentence.
- The event has started.
- The event has ended.
- The event has been canceled.
- The event has canceled.
The first 3 sentences sound natural to my ear but the last sentence doesn't. However, I couldn't explain why. With the last sentence, it looks like the meaning is that the event canceled itself which doesn't make sense. However, in the first and the second sentences, started
and ended
don't seem to mean that the event started and ended itself but started and ended by something so they make sense. The third sentence also makes sense compared to the last sentence.
Can anyone clarify what is wrong with the last sentence or is it natural?
