COLLINS ENGLISH USAGE says:
"sth doesn't happen any more/ anymore/ any longer" or "sth no longer happens", but not "sth no more happens" or "sth happens no more".
Then are these sentences (from the corpora) not fine?
She slumped against the kitchen door. She could cry no more; her face was so blotchy her eyes felt swollen shut.
No doubt there would be more tears until he could cry no more.
I'm raising this question because in my textbook there's also such a sentence:
At last when I could cry no more, I looked about me.
Could I ask native English teachers to help me please? Thank you in advance.
