What technique involves expressing an idea through juxtaposition of contrasting ideas, such as "bittersweet"?

The technique of expressing an idea through juxtaposition of contrasting ideas is best captured by the term "oxymoron." An oxymoron is a figure of speech in which two seemingly contradictory terms appear in conjunction. Examples include phrases like "bittersweet," "deafening silence," and "jumbo shrimp." These expressions effectively convey complex emotions or situations by combining opposing terms, allowing for a deeper understanding of the nuances present within a single idea.

In contrast, a paradox refers to a statement that seems self-contradictory or illogical, but upon closer inspection, may reveal an underlying truth. Hyperbole, on the other hand, involves deliberate exaggeration for emphasis or effect, rather than contrasting ideas. Parody is a form of satirical imitation that humorously exaggerates styles or themes of another work and does not focus on juxtaposing contrasting concepts. Therefore, the correct answer focuses on the specific technique of combining opposing terms to express a nuanced idea, which is characteristic of an oxymoron.
