Final answer:
The excerpts provided do not give a direct answer to the question about what Othello calls Desdemona. However, in the play 'Othello', he calls her names like 'strumpet' as his suspicion and jealousy grow. Understanding these language shifts is crucial to analyzing the themes of the play.
Step-by-step explanation:
The presented excerpts do not directly answer the student's question about what Othello calls Desdemona during their argument in Shakespeare's play "Othello".
However, examining the text of "Othello", one can find various instances where Othello's language towards Desdemona changes as the tragedy unfolds, especially under the influence of Iago's manipulations. For example, he refers to her with terms ranging from fair and gentle to, later in the play after his jealousy has been stoked, "strumpet" or "false".
It's important in studying Shakespeare to observe the changes in Othello's language and attitude towards Desdemona which represent his tragic downfall and the overall themes of jealousy, trust, and honor in the play.
