"In case" or "in cases"? [closed]

Solution 1:

It depends on the situation in which you're using it.

"In case" would be properly used in this context: I will bring an umbrella just in case it rains.

"In cases" is less frequently used. It would be properly used in the context of: In cases when your chest is in a lot of pain, you may need to go to the doctor.

Solution 2:

"In case" addresses one specific instance, and is often used in places where you could substitute "if"; "in cases" speaks to a number of different possibilities, and one can substitute "situations" for "cases" in these usages:
