In "Seeing like a state" of James C.Scott there is a sentence at the beginning of a paragraph (Acknowledgements xi):
There are a good many scholars whose writings opened up new perspectives for me or provided outstanding analyses of issues that I could not have hoped to study so comprehensively on my own.
What worries me is a good many scholars. Is this some type of inversion or ancient English? Is this grammatically right? Why a is here?
I thought that appropriate version would be There are many good scholars. Am I wrong?
