Vertimas - Anglų-Čekų - The language being taught

For example, you have a french lesson commented in english :
« "Bonjour" means "Hello" »
If you want to translate the lesson into italian it will be :
« "Bonjour" significa "Buongiorno" »

In this example the french language is the taught language and the english and spanish languages are the languages used to comment the lesson. "Bonjour" is kept untranslated.
