My contribution focuses on the rhetorical structures found in the verses and laisses of the Cantar de mio Cid. It examines the phonetic, semantic, and syntactic-metrical repetitions that give the elocutio of the Cid its unique form and expressive power. My thesis posits that these rhetorical repetitions reshape, embellish, and interpret the primary linguistic foundation of the verses. They create interpretations, valuations, and «secondary» signifiers, as defined by Lotman, that overlay the «primary» statements of the verses and laisses. Simultaneously, these repetitions transform the text with surprising word and sound combinations, a variety of rhetorical figures, and a tendency toward supralinguistic innovation, turning it into an aesthetic artificium that demands admiration and demonstrates a high level of metalinguistic awareness and literary professionalism. The Cid favors repetitions that juxtapose phonetic similarity with semantic incongruence. From a rhetorical perspective, this includes homonymy, paronomasia and tmesis, which are central to my analysis. These rhetorical figures are also significant because they reference potential pretexts, primarily Latin literature. The author of the Cid, who combines similarity and dissimilarity in unusual ways, draws on the rhetoric of classical Roman and medieval Latin writings. My concluding thesis asserts that he is undoubtedly a well-educated Latinist.
