I have a question and I hope you can help me.
Which version is correct?or perhaps both?
'ringing of the bell' and 'ringbell'?
More context would be helpful, but I can say that 'ringbell' is probably not what you want.
One can say something like, 'The ringing of the bell woke the people early in the morning.'
I hope this is helpful. Feel free to respond if you would like further clarification.
