Trina

Trina is an English given name that originated as a short form of Katrina, itself a Scandinavian and Low German variant of Katherine. Katherine derives from the Greek name Aikaterine, whose exact root is disputed but has long been associated with the Greek word katharos, meaning pure. The name gained independent use in English-speaking countries during the twentieth century. Related forms include Katrina, Karina, and Trine.
