CLaSSES (Corpus for Latin Sociolinguistic Studies on Epigraphic textS) is an annotated corpus for quantitative and qualitative sociolinguistic analyses on Latin inscriptions. It allows specific researches on phonological and morphophonological phenomena of non-standard Latin forms with crucial reference to the typology of the text, its origin and chronological collocation. This paper presents the first macrosection of CLaSSES, focused on the inscriptions from the archaicearly period.
