Jozef Konrad Korzeniowski - one of the giants of the literature in the English language in which he wrote.
Conrad was very heavily edited, and many many passages in his works are suspiciously similar to his wife Jessie's prose style. The ideas, themes and plots were certainly his but behind most great men there is often a great (and uncredited) woman.
And one of the greatest regrets of his life was that his ability with the Polish language declined over the years.
PS Most foreign teachers in Poland are just drop outs who couldn't find work in there own country.
God alone knows what kind of native-speaker Teachers you've met. Most here are professional.
I laughed, it was also an arrogant statement to say a non native is better than a native...Only a Pole would make such a statement.
Some of them indeed do. Some Polish 'teachers' of English barely speak the language themselves and pass on the most appalling mistakes to their students who take it as gospel.
the marvelous literature in the English language authored by a Pole.
And his English wife.
Barely speaks Polish though.
Then he's a native speaker of English rather than Polish.
