I want to know the answer to the following question:
What language did Catalan descend from?
All the background I'm provided with is that "By the 9th century, Catalan had evolved from Vulgar Latin on both sides of the eastern end of the Pyrenees, as well as the territories of the Roman province of Hispania Tarraconensis to the south.". Is that enough to answer the question?
Answer: yes
