Danish placenames dating from the colonial era exist for almost all major settlements in Greenland. Some of the places in question were founded as settlements under a Danish name, while others were originally Greenlandic toponyms. Very frequently, the Danish and Greenlandic names have different etymologies; while the former are often named after settlers or explorers, the latter usually describe geographical features. In 1983, a Danish law officially transferred the naming authority to the Greenlandic Home Rule. During the years before and after that, a complete set of Greenlandic placenames have ousted the former traditional Danish names. Danish names in Greenland are now mostly known or used by older-generation Danish-speakers or by Danes living in Greenland. Until recently, Greenland was still – both officially and "de facto" – bilingual, but Greenlandic has assumed the status of sole official language in Greenland, following the island's recent change from "hjemmestyre" (home rule) to "selvstyre" (autonomy).
