Abstract

This essay analyses nine previously unknown letters from South-eastern Umbria, sent in 1440-’41 from Foligno’s Priors to Spoleto’s ones: the documents are very interesting on the linguistic side, as they show local phono-morphological features; moreover, despite low dating and chancery subject, it is possible to notice a general lack of koinè elements related to Latin and Tuscan vernacular. This characterization is probably due to the belonging of senders and addressees to the same linguistic area, making unnecessary neither the use of balancing tendencies nor the elimination of local features
