Ja, visst kan jag ge dig en mening på svenska.
Kyllä voin antaa sinulle lauseen suomeksi myös.
Yes, sure, I can give you a sentence in Swedish/Finnish. (More or less, the languages are differently constructed but that's basically what one would say...)
I assume 'ja' means yes. But what does the rest mean?
And do you have to do something different to your computer to type English.
No. My computer has a Swedish keyboard, which means that characters like "/", "\", etc, are placed differently since the accented characters ("å", "ä", "ö"--don't know if your browser will display these, though; it depends on the installed fonts) need their own keys. The Swedish--the Finnish is identical to Swedish--alphabet is a superset of the English one. What I had to do was to tell KDE (my window manager of choice in Linux) to use a Swedish keyboard layout to get the Swedish characters to show up.
