What is the male version of Katherine?

The male version of Katherine is typically considered to be "Katherine's" diminutive, "Kathy," which can be adapted to "Kaden" or "Kurt" in some contexts. However, there isn't a direct male equivalent, as Katherine is derived from the Greek name Aikaterine. Variations such as "Caden" or "Kieran" may also be seen as alternatives, but they don't directly translate from Katherine.
