This inquiry explores the language of the Druze community in Israel as going through the process of convergence and a composite Matrix Language formation, resulting in a split language, a.k.a. mixed language, based on Myers-Scotton’s Matrix Language turnover hypothesis (2002). Longitudinal data of Palestinian Arabic/Israeli Hebrew codeswitching from the Israeli Druze community collected in 2000 and 2017 indicate that there is a composite Matrix Language formation resulting in a split language.
