- Määntik = Monntag = Monday
- Diischtik = Dienstag = Tuesday
- foiv = fünf = five
- drüu = drei = three
- ai = eins/ein = one
- nai = nein/nee = no
- aafigk = einfach = simple
- vielmol = sehr/schön = very much, e.g. danke vielmol = thank you very much (lit. "many times")
- mitenand = (lit. miteinander, "with each other") = y'all/to everyone here, e.g. hoi mitenand = hi, everybody (2+ ppl), whereas one would just say hoi to a single person
- glikhfols = gleichfalls = to you as well
And a few Swiss idiosyncracies:
- Merci is interchangeable with danke. This results in the funny, very typically Swiss construction merci vielmol (see above).
- Grüezi as a greeting. Derives from Grüsse (greetings).
- Ich wünsche dir/euch. The other half of the sentence (e.g. einen guten Abend) is implied. It's literally like saying "Have yourself" instead of "Have yourself a lovely evening."
- mühsam. This is a perfectly normal German word, which means "tedious". But either it's become a mainstay of colloquial German everywhere since the last time I was in Europe, or else it enjoys a special place in Swiss usage. At any rate, I hear it all the time, to about the same effect as "It sucks."
- -li and -i as extraordinarily common diminutive suffixes (see, e.g., grüezi above): Brötli, Schwänzli (for Schwanz, tail), Chüschli (for Kuchen, cake). The best I've heard yet is Fluggi to refer to an airplane.
- -sch instead of -est, usually the 2nd-person singular (i.e. "you") verb ending. E.g.: esch = ist (is), bisch = bist (are), fintsch = findest (find), wertsch = wirst (become). Hence:
- Esch güat. This corresponds to both Ist schon gut ("it's cool") and Ist gut so? ("is that okay?"), depending on how it's intoned.
More to come as I re-check my notes.
