- She married old.
- She married at old age.
Do these sentences mean the same?
Are they grammatically OK?
Yes, same meaning.
I would use “She married at an old age.” I would use this phrase instead of “She married old.”
That’s acceptable, just about.
. That needs to be changed to ‘in old age’.
Can I say: “She married late in life.”?
Is it acceptable?
Yes, you can.
