Yes, although He earns two thousand is an unusual sentence.
You'd be more likely to hear
He earns two thousand a week.
He earns ten thousand a month.
He earns fifty thousand a year.
The word ''thousand'' is not used in plural form if there is a number before it. But if you said ''thousands of people', that would be correct.
We don't say that with 'years'. We do use the plural when we talk about past centuries: the 1800s = the eighteen-hundreds = the years 1800 to 1899. So I suppose we might talk about the 2000s = the two thousands = the years 2000 to 2099. But I have never heard this. We're still not used to the new millennium and still haven't got comfortable with how we speak of it.
Talking about pure numbers, we can also use plurals: 'the total is somewhere in the two thousands' = it's somewhere between 2000 and 2999, but I'm not sure where. We talk about 'the low two thousands' (2000 to perhaps about 2300) and 'the low thousands' (somewhere over 1000 to about 3000, but not a larger number of thousands).
As I used above, we use 'years' with two end-points: the years 1800 to 1850.
It is quite clearer now. In fact in English you don't need to use the word 'years'.
My problem is that I was giving an instruction, in English, to not-English speaking people and for them the right expression comes with 'years' (for example, in English you say 'the Sixties', in Italian we say 'the years Sixties').
Conclusively, I believe, like you, that the right expression is "the two thousands" and not "the years two thousand/s". Thank you very much.
What is correct: he earns two thousands OR two thousand per month?
Do "we"? I realize I'm an AmE speaker, but I've read a lot of BE, and I've never seen that. Your example is apparently from a legal document, Tlaw, and such documents often include things that are never or seldom seen in regular writing or speech. Perhaps "two thousands and thirteen" is one of those.
Hi Kate. Exactly what I said. We (lawyers) use thousands with "s" in UK. On the contrary, when I work in New York, I rarely see the "s".
I am a lawyer not a translator. I find this website very helpful, and I am trying to help back with the "legalese" when I can.
p.s. - Besides The Telegraph - London newspaper - uses "thousands" with "s" as well.
