Final answer:
An oxymoron is a figure of speech combining two contradictory terms. 'Deafening silence' and 'bittersweet' are two examples of oxymorons highlighting opposite meanings used for poetic or rhetorical effect.
Step-by-step explanation:
The term you are referring to involves the use of oxymorons, which are figures of speech that combine two seemingly contradictory terms. Examples of oxymorons include phrases like 'quiet rage', 'original copy', and 'larger half', where the words have opposite or incongruent meanings. Two additional examples could be deafening silence, where 'deafening' typically describes a loud sound but is used to emphasize the absence of sound, and bittersweet, where something is simultaneously bitter and sweet, often referring to feelings or experiences that are both pleasant and painful.
