The greater part of A

seagullf someone says, "My sister has eaten the greater part of my pie.", what percentage of the pie has been eaten?

At least 51%. We can only guess that it is more.

It would imply more than 50% of the pie.

However, that sentence is unnatural for the context you mention! It's way too formal.

You can say something like:

"My sister has eaten most of my pie."
"My sister has eaten more than half of my pie."

I understand.
Thank you so much, Mister Micawber.

Many thanks, Teechr.
Actually, some dictionaries say "the greater part of something" means "most of something."
I don't know the nuance of this expression very well.

'Greater part' is just a little formal, that is all.

Thank you very much indeed.

Yes. It means a majority. It does not say exactly how much.

I understand.
Thank you very much indeed.
