There is no "Swiss language". Swiss people either speak German, French, Italian, or Rhaeto-Romansch. The language you would use would depend on which canton you are visiting.
German: dein Freund
French: ton ami
Italian: tuo amico
no problem
In Swiss German flowers are Blumen.
Swiss? Do you mean Swiss German, French, Italian or Romanish?
No. There is a country called Switzerland. Swiss is the adjectival form of Switzerland. You would say a person is Swiss because they are from Switzerland. Likewise, you would say you ate Swiss chocolate if it was from Switzerland.
I asked my friend for a chunk of his Swiss chocolate.
My Swiss (Swiss-German) Friend sometimes greets me when she writes to me with 'Hoihoi', search Swiss-german hoi and you should find something :)
In High German it's "Schmetterling"; in Swiss German they also sometimes say "Sommervogel."
