I want to know the answer to the following question:
What are the three main areas of southern Europe where Italian speakers can be found?
All the background I'm provided with is that "By far the most common romance languages in Southern Europe are: Italian, which is spoken by over 50 million people in Italy, San Marino, and the Vatican; and Spanish, which is spoken by over 40 million people in Spain and Gibraltar.". Is that enough to answer the question?
