"The child is eating the orange."
Translation:Barnet äter apelsinen.
If you're doing these on a mobile device, download the different language to your keyboard app and switch to it when when you're playing. On a computer, copy+paste+save the accented letters to a text file and copy them from it whenever you need. (if someone has a smarter way of doing it on the pc, please share. I'm Finnish so I have the åäö on default :D)
If you're on a computer: you should see the accented letters just below the box where you type in your answers, and you can just click on them.
If you're on a mobile device: I've seen other comments saying that you can hold down the letter key and it will show a choice of accented letters to choose from. (I don't use a mobile device, so I can't check this)
Yes, you can hold down the letter, and the options pop up. You can also go into keyboard settings and add Swedish. There will be a button next to the space bar where you can switch between English and Swedish. Be careful, though, not to change the language of the entire device.
