North Germanic Indo-European Vowel Shift Diphthongal Shift Fronting

Diphthong ou to Diphthong oi

This phonetic transformation involves the fronting of the initial element of the back rounded diphthong /ou/ and a subsequent adjustment in the second element, leading to the formation of the fronted diphthong /oi/. This shift typically results in a more fronted and often less rounded articulation of the diphthong.
