Student or Learner
I am facing a problem whether to use singular or plural after their in different cases.There is a sentence which I have read in a newspaper
1 I know enough marriages where people cheat on their spouse.
Why spouse is singular here ? Because people are plural and so they have different spouses,so it should be spouses.
Please tell me the logic why spouse has been used here ?
NOT A TEACHER
The only logic explanation that comes to my mind is that each person (usually) has one spouse.
Here's a thread in which you can find out more about this issue.
