Arendalsk, Arendal dialect or Arendal Norwegian (Bokmål and Nynorsk: Norwegian: Arendalsk, Norwegian: Arendalsdialekten; the Arendal dialect: Norwegian: Ændalsk) is a dialect of Norwegian used in Arendal.
According to the linguist Gjert Kristoffersen, a recent change is that the postvocalic pronounced as //ʀ// is vocalized to pronounced as /[æ̯]/, rather than dropped. The phonetic diphthongs pronounced as /[ʉæ̯]/ and pronounced as /[uæ̯]/ may be monophthongized and lowered to, respectively, pronounced as /link/ and pronounced as /link/, so that the words for 'to do gymnastics' and 'thorn' (which phonemically are, respectively, pronounced as //ˈtʉ̂ʀne// and pronounced as //ˈtûʀne//) vary in their phonetic realization between, respectively, pronounced as /[ˈtʉ̂æ̯nə] ~ [ˈtœ̂ːnə]/ and pronounced as /[ˈtûæ̯nə] ~ [ˈtɔ̂ːnə]/. This process may be extended to mid vowels.
Tonemes of the Arendal dialect are the same as those of the Oslo dialect; accent 1 is low-rising, whereas accent 2 is falling-rising.
