Just one more thing.
Which of the following sentences are grammatical?
Thank you very much for your cooperation.
1.I spent most of my holiday at home.
2. I spent the greatest part of my holiday at home.
3. I mainly/mostly stayed at home during my holiday.
4.For the most part, I spent my holiday at home.
5. Could you tell me what the weather will be like tomorrow?
All of them look grammatically correct to me.
For 3, both mainly and mostly work, but mostly is a better word for what you are trying to say.
