Hantec

Hantec is a unique slang spoken by the people of Brno. It is a special argot developed in Brno during the centuries of coexistence of native Moravians with medieval colonists like Germans, Italians, and Jews. In the 19th century and early 20th century it was very common among lower class people and but nearly incomprehensible to others. It is nearly extinct today, except among elderly people.

Example : The Czech word for 'sun' is slunce; in Hantec it is zoncna and 'tram' is šalina.
