Triin

Triin is an Estonian feminine name, a contracted form of Katariina, the Estonian equivalent of Katherine. Katherine ultimately derives from the Greek name Aikaterine, whose meaning is debated but is often associated with the Greek word katharos, meaning pure. Triin has been used in Estonia for centuries as an informal short form and later as an independent given name. Related forms include Triinu, Katariina, and the broader Katherine family across European languages.
