Should I use "in most case", "in most cases", "in the most case", or "in the most cases"? [closed]

Question

The differences are the particle and the number.

Answer 1

"Cases" is plural in the common expression "in most cases."

In most cases, the flu is not fatal.

That's a use of "cases" in the medical sense. Here is a more general example:

In most cases, I eat healthy food.

The phrase "in most cases" can often be replaced by the word "usually."
