Janko

Janko is a South Slavic and Slovak diminutive form of Jan, itself the regional form of Johannes, which derives from the Hebrew name Yohanan meaning God is gracious. The name has been widely used across Slovenia, Croatia, Serbia, and Slovakia, reflecting the broad medieval spread of the biblical name through Latin ecclesiastical tradition. It functions both as an affectionate short form and as an independent given name in these cultures. Related forms include Janez, Jovan, Ivan, and Hans.
