MOSADiscovery v2.1.4
While surfing your favorite websites in the language you're learning, select the word or expression you want to translate, right-click and select "Add to MosaLingua". You'll see a popup window showing the translation.
Then, add the word/expression to the extremely effective MosaLearning system as a new flashcard, and work on committing it to your long-term memory.
This plug-in is a great complement to our MosaLingua web and mobile apps!
