Thousand or Thousands

[Anonymous]

I am confused at when we should use thousand or thousands. Is "more than eighty thousands" is right? We can not add "s" after "thousand" in this sentence, can we?

This passage answers nearly the same thing as what you want:

================

Hundred VS hundreds

You can try to understand in the following way.

Hundred here is used as if it is an adjective.
So it is non-sense to add a "s" to hundred.
Thus it should be "5 hundred"

Eg:
- There are 5 hundred people in the street. (5 hundred is like an adjective to
describe the no. of people in the street)

However if "hundred is used as a noun, it can be plural. Eg:
- The birthday cake has a large "hundred" on top of it.

NB: Don't mix up with the following
- I spent several hundreds of dollars on clothing. [Since hundred is used as a
noun here, "s" is required]
