Diphthong oi to Close front rounded vowel

The diphthong /oi/ underwent a significant phonetic transformation in the history of Ancient Greek, evolving into the close front rounded vowel /y/. This change, primarily a process of monophthongization, simplified the two-vowel sequence into a single, distinct vowel sound.
