I want to know the answer to the following question:
What is the reason for French and Italian not being very mutually comprehensible?
All the background I'm provided with is that "In one opinion, this pattern is clearly present among the modern Romance languages, with Italian and Spanish having a high degree of mutual comprehensibility, which neither language shares with French, despite some claiming that both languages are genetically closer to French than to each other:[citation needed]". Is that enough to answer the question?
