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 fact, French-Italian and French-Spanish relative mutual incomprehensibility is due to French having undergone more rapid and more pervasive phonological change than have Spanish and Italian, not to real or imagined distance in genetic relationship.". Is that enough to answer the question?
Answer: yes
