Hello,

So today I ran across a problem: For example, when you have a sentence:

I earn 2 thousand dollars a month. - The word "thousand" here doesn't take a plural here.

There were thousands of people at the party. - Here the word "thousand" is plural because you are saying that there were x thousand people.

When you have a question: "How many thousand/s are there in a million?" should there be plural or singular?

Could you explain it?


Thank you for your help

That is because "thousand" is an attributive noun, also called a noun adjunct. It modifies another noun - dollars.

Noun adjuncts are singular.

e.g.

The horse can jump a six-foot fence.
I need a two-meter length of cloth.
Crossing the Atlantic used to be a seven-day journey by steamship, but now it is a seven-hour flight.


When we use a number as a regular noun, the singular-plural rules apply like other nouns.

There are trillions of stars in an average galaxy.

How many students are in the class?
How many thousands are in one million?
