Kathi

Kathi is an English given name functioning as a short form of Katherine, which traces back through Latin and Greek Aikaterine to a root of uncertain origin, though it has long been associated by folk etymology with the Greek katharos, meaning pure. The name gained wide use across medieval Europe largely through the veneration of Saint Catherine of Alexandria. Kathi sits alongside other informal variants such as Kathy, Kathie, and Kate, all of which derive from the same Katherine base.
