I am quite confusing with the cases. How can I know what to use, -en or -et to make the noun?
It depends on the grammatical gender of the noun. Kjøtt is neutral, so you add -et
I'm having a bit of trouble pronouncing kjøttet- it sort of sounds like the english "shelter" without the l, or "sh-oat-er" sound, is this correct?
It is pronounced as /shawt-tah/
you could try listening to the pronunciation at forvo.com/word/kjøttet/
That site would have been far more useful if the person doing the pronunciations made sure they didn't have so much background noise.
I do not have a keyboard that will let me spell with norwegian accents. I keep being picked up on spelling.
Cut and paste them. Also you can try: alt 0198 (for Æ), alt 0216 (for Ø), alt 0197 (for Å), alt 0230 (for æ), alt 0248 (for ø), and alt 0229 (for å).
Try installing Norwegian language pack for the keyboard you are using.
So 'I eat ❤❤❤❤' is wrong...
