"Nie czuję bólu."

Translation: I do not feel pain.

[CassandraSpeaks]

Because I am a Bond villain

[Karjze]

or, a robot!

[Paco_Escipion]

Why is it "bólu" in this sentence, but "ból" for "I feel pain"?

[va-diim]

Negation in Polish changes the noun case to genitive

[Jellei]

Negation changes the Accusative case to Genitive :) All the other cases stay the same when negated.

[va-diim]

RU: Nie czuwstwuju boli.

[Keegan317005]

"I do not feel ache" probably shouldn't be accepted. Perhaps "I do not feel an ache"?

[va-diim]

You are correct. A noun needs an article when there is no other noun determiner used.

[Arnoldpitt]

perhaps "any" is the appropriate article here

[Jellei]

Makes sense, added.

[Trofaste]

You're right, removed it.

[Jellei]

And added "an ache".

[Ten_Pies_I_Brew]

Does this mean "I don't feel pain at this moment", "I don't feel pain ever", or either?

I wrote "I'm not in pain" and it was rejected.

[Jellei]

Without further context - both, although the first one seems more likely ;)

Your answer makes sense to me, added.

It is strange that here, the o kreskowany doesn't become a nornal o

[Jellei]

It's "ó kreskowanE", although I don't know how to explain why.

Well... It's hard for me to say how often ó changes into o... for me it's obvious that it doesn't do it here, but then again natives usually don't think of any rules, they just know how to use the language ;)

[gkouye]

Nie czuję bólu, bo wypiłem za dużo śliwowica... lol

[Jellei]

"śliwowica" is feminine, so here in Genitive (because of 'dużo'): śliwowicy :)

Well, that's not a traditional alcohol in Poland, but well, to each their own ;)

[Ollyfer]

Indianie nie czują bólu.

[steve571213]

please could you explain why it is not - nie czuję się bólu

[va-diim]

Because you're feeling something, in this case pain. Reflexive here would mean that you're feeling yourself somehow, not physically though.
