This study describes the form and function of Moroccan Arabic cognate and analogical curses. Drawing on scholarship on curses in other Arabic dialects, it provides a comparative discussion of the Moroccan variety and analyzes a corpus of cognate curses that includes many of the standard members of the genre. It then defines the analogical curse, arguing that this particular type of curses derives from proverbs based on the simile. It suggests that the speech genre of curses in the Arabic dialects goes back to a common repertoire that predates the Islamic period.
