Hello. You did not show the text to which this question refers, which makes it impossible to answer it accurately.
However, it is likely that you are referring to the Aegean course for Lysander, where words of figurative and connotative meaning are used. In this speech, Ageus uses these words to highlight the vile, sorceress and evil nature that Ageus believes Lysander has. That's because he shows in a connotative way how Lysander "bewitched" his daughter by making her fall in love with him, a man she is not promised to. He also uses the connotative concept that implies that Lysander is a thief and therefore stole his daughter's heart. In other words, the connotative words present negative concepts that reflect the Aegean's perception of Lysander.
