Context: <response>: This change dey interesting from a sociolinguistic point of view because e be like say e happen recently, for the 1970s, and na older well-educated women from the upper middle classes start am. The lowering of the diphthongs don dey happen for many Dutch dialects for long time, and e dey similar to the English Great Vowel Shift, and the diphthongisation of long high vowels for Modern High German, wey happen centuries ago reach the state wey we dey see for Polder Dutch now. Stroop dey reason say the lowering of open-mid to open diphthongs na phonetically "natural" and inevitable development and say Dutch, after e don diphthongise the long high vowels like German and English, "suppose" don lower the diphthongs like German and English too.
