Kati

Kati is a Finnish, Estonian, and Hungarian short form of Katariina or Katalin, which ultimately derive from the Greek name Aikaterine. The deeper roots of Aikaterine are uncertain, though it has long been associated by folk etymology with the Greek word katharos, meaning pure. The name gained widespread use across Europe largely through the popularity of Saint Catherine of Alexandria, a legendary early Christian martyr. Related forms include Katja, Kaarina, and Kata.
