Il volgare trentino in una tariffa rivana del 1409

This article analyses the language of an early fifteenth-century manuscript concerning the muta (excise taxes) of Riva del Garda (Trentino, Italy). The linguistic interest of said document, written mainly in Latin, lies in the number of vernacular terms and their nature (mostly mercantile goods). The authors provide a partial edition of the source, which includes also a series of business notes, a linguistic analysis, a glossary and onomastic indices. In order to better characterise the document’s linguistic phenomenology comparisons are drawn with other Northern Italian Vernaculars (such as Veronese and Bresciano) and with the few known texts from medieval Trentino.
