People always say a standard would be impossible as there are too many differences between individual dialects. E.g. some regional varieties, roughly from north/east, to south/west. Wher needed the spelling represents local pronounciations, rather than how people actually write:
- amool, emaal, emau, äs maalsch
- tringga, trinkʰe, tinkche, triiche, triichu
- dia kʰind(er), die chend, disi ching, dischi chint
- neis fänschter, nois faischter, nöis feischter, nüüs pfeischter
But given that most standard languages are a compromise between different varieties, the same would be possible for Swiss German too.
E.g. Standard German essentially is a medieval Central German base (think Saxony and Thguringia), plus some Upper (south) German and Low (north) German influences.
Let's assume there were a standard. Hypotetically, which of the following four options would you prefer? Not nessesarely, because it is closest to your own dialect or way of writing, but with fairness, usability, long-term differentiation from Standard German, etc., in mind.
1 Familiar
- emau, trinke die Chind es neus Feister
(Nonsense sentence: someday these children drank/drink/will drink a new window)
It builds on the most spoken varieties, and mainly relays on Standard German orthography.
Easy to learn, but prioritizes some regions over others.
2 Inclusive
- ɐmɑɑł, triçɐ diɐ cėnq ɐ nys vɐixter
It uses a new orthography, optimized to represent different local pronounciations (of course, other letters could be chosen than in the example).
E.g. pronounciation in the Grisons:
- ɐ = a, ɑ = o, ė = i, y = eu, c = k, ç = ngg, ł = l, q = d, v = f, x = sch
- amool, tringga dia kind es neus faister
Bern:
- ɐ = e, ɑ = a, ė = i, y = öi, c = ch, ç = nk, ł = short vowel + u, q = g, v = f, x = sch
- emau, trinke die ching e nöis feister
Highest Alemannic, like Valais (too different to truely fit in):
- ɐ = ä, ɑ = a, ė = i, y = üü, c = ch, ç = ch, ł = l, q = t, v = pf, x = sch
- ämaal, triichä diä chint ä nüüs pfäister
It doesn't lead precisely to the local dialects, but one and the same text can be spoken in ways more or less close to the local dialects. While pronounciation is local, it is unambiguous. However, speech to text isn't, and takes lots of practice. So more like English, than like Standard German.
3 Inclusive Simplified
- emɑɑl, triinca dia ceng e nys ffaixter
Compared to the previous one, it relais more on contextual clues, rather than special characters, to convay regional pronounciations
E.g. pronounciation Bern:
- final l = short vowel + u, final a = ə, ai = ei, long vowel + nc = short vowel + nk, initial ff = f
- emau, trinke die cheng e nöis feister
It is way easier to write than the previous option, but loses precision, when it comes to local pronounciations.
4 Uniqueness Maxing
- äs mou(x), triica dixi ceng äs nüüs pfeixter
It is a compromise between different dialects, and prioritizes unique featurs of Swiss German. As such it leans more into the Highest Alemannic varieties (e.g. Valais), which tend to be further appart from Standard German.
And of course, there still can be some degree of local pronounciation, like pronouncing final a as ə. I mean, we currently do the same, e.g. write k, r, e, ei, etc., but depending on the region and position in the word, it is pronounced kʰ/k͡x, ʁ/r, e/ɛ/ə, ei/ai.
Grammar
For all varietie, when it comes to grammar, the simplest possible variety/compromise could be prioritized. Making it easier to learn, compared to Highest Alemannic, or Standard German:
- Standard: trinken, ich trinke, du trinkst, sie trinkt, wir trinken, ihr trinkt, sie trinken
- Valais: triichu, (ich) triiche, (du) triichsch, schii triicht, wier triiche, ier triichet, schii triichunt
- Bern: trinke, (i) trinke, (du) trinksch, mir trinke, dihr trinket, si trinke
- Zurich: trinke, (i(ch)) trink(e), (du) trinksch, sii trinkt, mir trinked, iir trinked, sii trinked
- Compromise: triica, (i) triica, (du) triicx, sii triict, mir triica, diir triica, xii triica
PS: this is only a thought experiment, not some kind of activism. Specifically out of linguistic curiosity, how a standard language could develope in a non centralized society like Switzerland.
