Answer:
The modern Italian language was strongly influenced by his writings.
Step-by-step explanation:
Dante is considered to be the father of the Italian language. Before the Divine Comedy people in Italy wrote using Latin while Dante wrote in Florence dialect. He played a big role in setting the Florence dialect as the standard. And besides the political fragmentation of Italy at that time there was also a problem where you couldn't understand other people even if you moved a few cities in distance. Italy celebrates the 750th anniversary of his birth in 2015.
