"Who teaches you?"
Translation:Kto was uczy?
"Kto was uczy" is also acceptable and sounds more eloquent as the most important part of a question is usually at the end of a sentence.
"Kto was uczy" is one of the starred answers, and every accepted answer ends with 'uczy'.
We're not very fond of sentences like "Kto uczy was?" - it's not wrong, but it is better to avoid putting a personal pronoun at the end of the sentence if only it can be avoided. Otherwise, it sounds like "Who teaches YOU?"
Added now, thanks. Please note there might be some delay before the course will reflect changes made in the Incubator.
