Language families and similarity We know that in the world there are a lot of languages. Each one different to others but some of these languages have some similarity between they. For example we can consider all the "Romance languages": Italian, Spanish, Portuguese and French and others. They have a similar grammar and also a lot of words are almost the same. So, obviously is easier learn these (if you already know one) that languages of another family. In my opinion is so interesting however to study languages of another family, because that's open to you a very different world, and a "learning experience" so different.
