I should like to know if someone has an information about how
was called the latin language until the X century.
Maybe you will smile about " how was called the latin
language" but my question must be meant if there are any
ancient texts which are
telling us about " lingua romanorum" or there the therm
"latin" is the only word regarding the latin language?
I ask it because it seems a bit strange to me that from all
neo latin folks just the romanians say " romanian language"
which is to be meant as " roman language" so how many umanists
from 15-17 century observe.
So , do we know about any texts which are calling the latin
language as " roman language"? or there is just "latin
language"?
