What was the vernacular spoken language in 13th century Naples? A precursor to modern Neapolitan?
As I answered here, in Italy, in XIII century, the spoken language was the vernacular language, the “official” language was Latin.
Latin remained in use in written documents and among a minority of educated persons, mostly priests and monks of the Catholic Church, who probably used it often as a spoken language.
Obviously, through Italy there were a lot of different shades of vernacular language. The non-sporadic written use of the vernacular language begins in the thirteenth century, in Naples later, in the fourteenth century.
