On several Vikipedio pages about physical laws or mathematical theorems, I have found expressions like [leĝo/teoremo X] statas, ke… (here, here and here). To me, it looks like a crude Anglicism translating "theorem X states that". According to PIV, stati means "esti en ia difinita stato", which makes no sense when expressing the content of a theorem. But the large number of occurrences of that makes me doubt.

Is it indeed a misuse? If yes, what would be the correct verb? I would go for asertas, ke, which seems actually quite common.

    @Mawg If you are referring to asertas, ke — that comma is mandatory in Bulgarian, and I believe not only Bulgarian. Esperanto also requires it, as ke begins a subclause: PMEG Oct 20, 2016 at 10:08

    That comma is also mandatory in German. But not in French (and other Romance languages, I think). Zamenhof probably draw inspiration from German / Slavonic languages on that question.

Yes, statas ke is definitely wrong. I agree with asertas, ke. Vikipedio should never be used as a reference of good Esperanto ;-)


I agree that statas ke is wrong. Asertas ke is good.

Possible alternatives:

  • diras
  • indikas
  • klarigas
  • tekstas

Benson (CEED) has aserti and diri.

If you don't believe that theorems can speak, you can try something like en la teoremo X oni diras ke...
