The Danish language has a number of regional and local dialect varieties. These can be divided into the traditional dialects, which differ from modern Standard Danish in both phonology and grammar, and the Danish accents, which are local varieties of the standard language distinguished mostly by pronunciation and local vocabulary colored by traditional dialects. Traditional dialects are now mostly extinct in Denmark, with only the oldest generations still speaking them. The traditional dialects are generally divided into three main dialectal areas: Jutlandic dialect, Insular Danish, and East Danish. Since the Swedish conquest of the Eastern Danish provinces Skåne, Halland and Blekinge in 1645/1658, the Eastern Danish dialects there have come under heavy Swedish influence. Many residents now speak regional variants of Standard Swedish. However, many researchers still consider the dialects in Scania, Halland () and Blekinge () as part of the East Danish dialect group. The Swedish National Encyclopedia from 1995 classifies Scanian as an Eastern Danish dialect with South Swedish elements. Also Bornholmish belongs to the East Danish dialect group. Jutlandic is divided into Southern Jutlandic and Northern Jutlandic, with Northern Jutlandic subdivided into North Jutlandic and West Jutlandic. Insular Danish is divided into Zealand, Funen, , and Lolland-Falster dialect areas – each with additional internal variation. The variant of Standard Danish spoken in Southern Schleswig is called South Schleswig Danish, the Danish variant on the Faroe Islands Gøtudanskt. Danish shares many similarities with the Norwegian (Bokmål). Also North Frisian and Gutnish (Gutamål) are influenced by Danish. and tonal accents The realization of has traditionally been one of the most important isoglosses for classifying geographic dialect areas.
