In which prefix is the meaning associated with the concept of 'more than normal'?

The prefix "Ultra-" derives from Latin, meaning "beyond" or "on the other side." In a medical or scientific context, it indicates a degree that exceeds what is considered normal or standard. For instance, "ultrasonic" refers to sound waves with frequencies higher than normal human hearing. This reflects the idea of something that is "more than normal" in its intensity or measurement.

The other prefixes have different connotations: "Super-" generally means above or over but does not specifically convey the exceeding of normality in a quantitative sense. "Tachy-" is often used to denote speed, specifically indicating something fast or rapid, and does not imply a comparison to a norm. "Trans-" typically means across or through, indicating a form of movement or change but not necessarily more than normal.
