This paper tackles the topic of Latin influence on Italo-Romance syntax by addressing the question how to combine the analysis of structural data with socio-historical reflections. It views the genre and discourse tradition of a given medieval text as governing the extent to which Latin is used as a model in this text. The paper proposes a methodology which incorporates consideration of the historical, cultural, and sociolinguistic context of language change, focusing on evidence from the development of present participles in Italo-Romance. The main conclusion is that, rather than talking about the general influence of Latin syntax on Italian, one should be examining the influence of particular Latin models on the syntax of different texts written in Italo-Romance varieties in a given historical period.
