"I am not American, but Mexican."

Translation: Nem amerikai vagyok, hanem mexikói.

[AKicsiMacska]

Why is "Én nem amerikai vagyok, hanem mexikói" not accepted??

[jzsuzsi]

It is good. Report it as "my answer should be accepted."

[ude.udeh]

Mexicans are Americans too

[Liggliluff]

Yes, in the sense of American from Americas, but not American as from USA.

Hungarians call all people from Netherlands as Hollandic, even though Holland is just a region in Netherlands. That's an example of the reverse.

So it's better to accept these errors, or let rename USA to Usonia or something.

[wyqtor]

Nem vagyok amerikai, hanem mexikói - would this be correct too?

[linguafiqari]

I believe you would then want to contrast against the verb - maybe something like "Nem amerikai vagyok, hanem leszek" ("I'm not American (yet), but I will be").

Magyar beszélőknek - a fölött lévő elmagyarázás helyes?

[mizinamo]

Your example should probably have "Nem vagyok amerikai..." to make it clear what you are explaining :) i.e. that the "nem" is in front of the thing that you are contrasing - here, the verb.

[Mznmzn]

En nem amerikai vagyok hanem mexikoi is not accepted. Why adding a personal pronoun is a mistake?

[MortenI]

What about "En nem amerikai, ..."? I thought "vagyok" was optional?

[MGeri92]

[Native Hungarian here]
"vagyok" could only be optional, if the context had already used some form of this word. E.g.
- Te amerikai vagy, ugye? (= You are American, aren't you?)
- Nem amerikai [vagyok], hanem mexikói. (= [I am] Not American but Mexican.)
In your sentence, it is the subject (én) that can be omitted.

en nem vagyok amerikai hanem mexikoi. Why was this not accepted?
