"Croatian sign language (Hrvatski znakovni jezik, HZJ) is a sign language of the deaf community in Croatia. It has in the past been regarded as a dialect of Yugoslav Sign Language, although the dialectical diversity of the former Yugoslavia has not been assessed.
In 2004, a project to establish a grammar of HZJ was started by researchers at Purdue University and the University of Zagreb.
By law Croatian Radiotelevision is to promote the translation of programs into HZJ. Major centres of education in HZJ are found in Zagreb, Split, and Osijek."
