Some Western Swiss German dialects lik Bernese German have preserved the old diphthongs /ei̯, ou̯/ , but the other dialects have /ai̯, au̯/ like Standard German or /æi̯, æu̯/ . Zurich German , and some other dialects distinguish primary diphthongs from secondary ones that arose in hiatus : Zurich German /ai̯, au̯/ from Middle High German /ei̯, ou̯/ versus Zurich German /ei̯, ou̯/ from Middle High German /iː, uː/ ; Zurich German /bai̯, frau̯/ 'leg, woman' from Middle High German bein, vrouwe versus Zurich German /frei̯, bou̯/ 'free, building' from Middle High German frī, būw .
Now, why are we making these three groups? Well, because they are different. At least different enough for German to be like “Oh, oh, oh, hooooold up. I soooooo need three different verbs here.”
People all around the globe were like “What the hell man?”.
God and all the Gods were like “What the hell, man?!” .
“What the hell, ‘man?” howled the wind
“What the hell, ‘man?” growled the bear.
“What the hell, ‘man?” sang the birds, high up in the air.
And finally German sighed and said
“Fine. I’ll try, I’ll try it with one. But I need three structures, a prefix and a reflexive to get it done.”
And that’s the mess we’ll look at today,
so follow me. I know the way.
“Uh… will that all be in rhymes now, Emanuel?”
Nah, don’t worry. Just old fashioned ‘splaining.
