Tonogenesis: A diachronic typology

This article presents the Database of Tonogenetic Events (DTE), which describes 259 tonogenetic events from 104 genealogically and geographically diverse language varieties. The DTE allows us to identify the main types of reported tonogenesis triggering contexts, the types of resultant tones, and their effects on pitch. We illustrate the usefulness of the database with case studies addressing (i) the frequency of different types of tonogenesis, (ii) the diachronic pathways linking phonological triggering context and resultant tone, and (iii) areal trends. We also discuss the shortcomings of the database with respect to the diachronic typological study of tone.
