What term is used for something original, new, or different?

The term that signifies something original, new, or different is "novel." In this context, "novel" refers to ideas, concepts, or creations that are groundbreaking and not previously encountered, emphasizing uniqueness and innovation. This term is often used in various fields like literature, science, and art to describe works or ideas that introduce fresh perspectives or methodologies.

The other options present meanings that do not align with the concept of originality. For instance, "trite" suggests something that is overused and lacking in freshness, while "utility" refers to the usefulness or practicality of something, not its originality. "Prevailing" denotes something that is dominant or widely accepted at a given time, which does not convey the idea of newness or uniqueness inherent in the term "novel."
