Getting the app
You would like to develop reading competency in the four most important Romance languages? (This is the condition for developing listening comprehension, writing and speaking skills.) Then you should use this app.
It comprises in 9555 series the 5000 most frequent words of French, Italian, Portuguese and Spanish in combination with their German and English equivalents. By only reading a series like activité-attività-actividade-(BLANK for Spanish you have to fill in [actividad])-Aktivität-activity you will link your already disposable knowledge to the word you are going to learn. If you fill in an erroneous form, the correct one will be visualised automatically.
There is no better way to acquire plurilingual reading competency.
