Figures of pathos

Although any figure of speech may be employed to evoke an emotional response, many figures are specifically designed to do so, or else are themselves functions of the emotional state of the speaker. In a legal context, pathos has historically been used in the statement of facts, as part of witness handling and also in the closing speech which usually tries to bring together all of the three key elements of a speech - the figures of ethos, pathos and logos.

An example of pathos would be the following question:  

"Why are you so stupid?" 

This use of epiplexis, a kind of rhetorical question, does not seek the information it ostensibly asks for, but is likely an attempt to provoke anger in the listener.

Aposiopesis - Breaking off suddenly in the middle of speaking, usually to portray being overcome with emotion.
