Should I use "doctor's bills" or "doctors' bills" in the following?
All the money went on doctor’s bills.
I'd appreciate your help.
There are four scenarios, where three and four are semantically equivalent:
Nota bene: If there is one doctor and many bills, the determiner "a" must be used, as in Line One.
The last one is the use of a noun as adjective. Sentence three and four can express the idea of more than one doctor and more than one bill.
You can use went on, but I prefer went to.
