Jancsi

Jancsi is a Hungarian given name, a diminutive form of János (John). In Hungarian usage, Jancsi can function as a nickname or affectionate form of János, and it can also appear as a standalone given name in modern usage within Hungarian-speaking communities.

The form is formed by adding a diminutive suffix to János; Jancsi is commonly used among family and friends, and in literature and popular culture. It remains primarily associated with Hungarian contexts.

The best-known reference is Jancsi és Juliska, the Hungarian version of Hansel and Gretel. In this tale, Jancsi is the resourceful boy who, with his sister Juliska, encounters a witch in the forest and ultimately outwits her. The story has numerous variants and is a staple of Central European folklore and children's literature.

In contemporary Hungary, Jancsi may appear in fictional character names or as a playful nickname for boys named János; it is less common as an official given name today, though it remains recognizable due to the fairy-tale association.
