On the other hand, 'you have right' translated literally to polish is 'masz prawo' which is exactly what 'you have right' means. I think 'masz racje' -> 'you have correct' -> 'you are correct' would be a better way to show the difference.

And the longer I think about the word 'racja' the less I'm confident I'm able to explain precisely what it means using english.

I guess that's part of the fun of learning other languages, I will never understand articles in english and I made peace with it. Now I'm also learning spanish and subjuntivos drives me nuts but spanish and polish grammar are surprisingly similar (waaay closer than both are to english)
