Translation of words

Hello everybody, I’m learning English by help of lingQ, but don’t know, why I get the translation of words in Russian?

And I didn’t understand how to mark unknown words with yellow,

A lot of thanks for help!

Do you want Hungarian to be your dictionary language? If so, you can change it from Russian to Hungarian under the settings. Click on the settings button on the home page (gear icon next to the tabs) and when the settings popup appear under the Reader Settings you will find an option to change your dictionary language.

No, the best would be German, because that is my mother language, Hungarian I also speak, but for learning German is the best one.
