@Turi@kitten I, a native speaker, have long since made peace with the fact that the second R in "Rückfahrt" is a luxury I cannot afford. To pronounce it would require the strength of a thousand opera singers and the throat of an elder dragon. That R demands acrobatics no human should be asked to perform before being caffeinated. "Rückfahrt"? No. I offer you "Rügfad" (or, if it really needs to be formal, a "Rückfaat") - a modest, humble tribute to efficiency and survival. The second R? I leave it for the poets and mad ones.
@Turi@kitten either way, there will always be places you will be recognized as a non-native local. (we speak Untermainländisch (Unnämåländisch) here, which is a south hessian dialect and belongs to the "RMV-Hessian" regiolect, but very much geologically in Bavaria). Sure, I can choose to speak dialect or high german, but some things are just so engrained (like dropping that R) that it's just impossible to do it differently even when really trying to speak as perfectly as possible...
i do wonder tho... i would have assumed that it's more of a northern thing to pronounce the R. and that upper bavarians would also just drop it. i need to make a poll, now i wanna know...
@Turi@kitten yeah palatinate gebabbel. i understand that pretty well still.
A while ago i had a very shocking experience: I've been south of Tübingen, rural obviously, and I understood exactly nothing of what people were saying... Upper Bavarian is also a special breed, but that was a lot more bearable to understand (and even learn to use a bit), but Swabian? Whatever they're doing to language is just wild (and amazing).
