Étude diachronique des prépositions latines ad et de

We are interested in this work to describe the semantic and syntactic evolution of the two Latin prepositions ad and de thanks to some concepts that underpin the theory of grammaticalization. To do this, we chose a body formed of two different states of language, namely the classical period through the examination of examples from the Divisions of Public Speaking and the Topics of Cicero and the Christian period through examples from the Apology of Tertullian. We found that the use of these prepositions is a trend that is growing increasingly and is consistent with the tendency to restrict the role of the time. This development, which results in the transformation of the typology of the Latin language of a typology typology synthetic and analytical language, and moving to the novel type we see today.
