Katarínus / Katarin / Katarino

Katarínus is a rare masculine given name, primarily found in Icelandic and Faroese cultures. It is a masculine form derived from the Greek name Aikaterine (Catherine), which has an uncertain but widely accepted meaning of 'pure'. While Catherine and its variants became immensely popular for females across Europe, masculine forms are much less common. The name likely entered the Nordic regions through religious influence, as Saint Catherine of Alexandria was a highly revered figure in Christianity. The 'us' ending is a common Latinate masculine suffix, adapted into the local linguistic context.
