How do the stylistic figures of Dante's Inferno directly impact the way poetry creates meaning?

In canto X, Virgil instructs Dante to "choose fitting words". Dante is truly a master of language; every word he uses combines the power of specific definition, sound, and symbolism to create truth and overall meaning. Pinsky stays true to Dante's intention and recreates Dante's overall meaning with fitly framed words as well. All over the Inferno readers find examples of literary figures creating deeper meaning with in the poetry. For this blog I will focus on the first three lines of Canto VII.

"Pape Satan, pape Satan, aleppe!"
          Plutus began in a gluttural, clucking voice.
          The courteous sage who knew all reassured me:

The first line is gibberish, yet the words sound as if they resemble the phrase "father satan, father satan, the first one." In the words of Nicole Pinksy, Dante's "skillfully written nonsense" "has succeeded in putting evocative gibberish the poem. This is an example of Dante using word definition to create meaning. He skilfully plays with the words so their exact definition is unclear yet the meaning is clear. In this first phrase certain sounds are repeated such as the 'p' and the 'eh' sound at the end of pape. Also the next line includes onomatopoeia words (clucking) which This provides a "gluttural" sound which causes the demonic words to pop out, and therefore add to the fear and disturbing feeling Dante experiences while in Hell.  Dante also uses a blend of chiasmus and antithesis The beginning of the line begins with confusion. The language is of demonic tongue. Yet it ends with the word "reassured". Instead of the beginning of the line paralleling the end of the terza rhima, instead the end of the line provides juxtaposition to the beginning of the line. This rearrangement of chiasmus gives the first terza rhima a complete feeling which causes this episode to stay inside the reader's mind. It also highlights how Hell is incomplete, or just-not-right, and slightly off-
balance.
