Origin

The character combines a horse () on the left with a component that sounds like "ken" on the right. The horse here acts as a classifier suggesting the domain of testing or verification — horses were often used for practical trials and tests in ancient times. The right component provides the sound hint for how to pronounce the character. Over time, the meaning shifted from the concrete idea of testing horses to the broader sense of verification, effect, and experimentation that the character carries today.
