South Jutlandic
Language (and especially spoken language) is not necessarily linked with national identification. Family ties and informal local contact across the border used to be very common, with South Jutlandic being the first language of both Danish minded and German minded people. Sometimes the purest South Jutlandic may be found among older people who identify as German. Since they have not attended Danish schools, their speech is not influenced by Standard Danish. With urbanisation in the recent decades this crisscross of dialects and national sentiment has faded, High German becoming the first choice everywhere, but often some South Jutlandic words are retained in the vocabulary.
