# I Have Darn Weird Confusion :S?

•  0
Suppose, he has a car and she has a car (don't mind who they are). They have a car or two cars? And is the term suppose to be their car or their cars? I always use plural when it's about different objects that are connected to the subjects but sometimes I get confused because I read something like this:

Ally and Joe bought a same Volkswagen model but they chose different colour(s) for their car.

I thought its suppose to be their cars because they don't share a same car but they bought two different cars. Can someone tell me the truth?

Suppose, he has a car and she has a car (don't mind who they are). They have a car or two cars? Tom and Suzy have a car: I understand they share the same car. Tom and Suzy both have a car: 2 cars. They each have a car: 2 cars.

And is the term suppose to be their car or their cars? I always use plural when it's about different objects that are connected to the subjects but sometimes I get confused because I read something like this:

Ally and Joe bought the same Volkswagen model but they chose different colours. full stop. We understand each car has a different colour. Or "for their respective cars".

I thought its suppose to be their cars because they don't share a same car but they bought two different cars. Can someone tell me the truth?

I don't know if it's the truth, but it sounds logical ...
Two people may own a car jointly. But in your example, each owns a car. Therefore, you are correct in using their cars.

Mom and Dad own a single car. You'd say, "Their car is in the driveway."

If Mom and Dad each owned a car, you'd say, Their cars are in the driveway.

It's fine. A word has been omitted, and it is probably the word "respective":

Ally and Joe bought the same Volkswagen model, but (each) chose a different colour for their (respective) car.

If you go for the formal, some would say "older", approach:

Ally and Joe bought the same Volkswagen model, but each chose a different colour for his car.
So... both their car and their cars are correct?!
