Edward Parmalee Morris was a scholar of Latin literature who published editions of Horace and Plautus. In this article he uses his intimate knowledge of the syntax of Plautus to address the conventions for understanding interrogative constructions in Latin sentences. This most thorough treatment of interrogatives is clearly organized and, despite being quite specialized, is quite understandable to the intermediate student of Latin. This would be particularly useful reading to students engaged in advanced Latin prose composition.
