Sardismos is the name, in several Latin works of literary criticism, for a combination of more than one language or dialect in a sentence. Quintilian (first century c.e.) uses the term disparagingly; the Christian author Cassiodorus (sixth century c.e.) uses it positively. A similar term, sardîstôn, is found in the rabbinic work Exodus Rabbah 2, created in the sixth-century Byzantine empire. This article is a short study of this term, the history of its misinterpretation and reinterpretation, its meaning in context, and its relationship to sardismos.
