Trina

Trina is a Scandinavian and Germanic short form of Katrina, itself a variant of Katerina and ultimately derived from the Greek name Aikaterine, whose precise root is debated but has long been associated by folk etymology with the Greek word katharos, meaning pure. The name gained widespread use in northern Europe, particularly in Scandinavia and Germany, as an independent given name rather than merely a nickname. Related forms include Trine, Katrina, Katharina, and Catherine.
