When I was watching ''Pippi Långstrump'' I heard the actors say things like ''våran pappa'' and ''vårat hus''. How is it translated? Shouldn't it be vår and vårt? Is it a thing in colloquial Swedish?
Sounds alright to me, but I can't hear the slow one. Perhaps it's a matter of tuning your ears?
so fäder is the plural of fader (and mödrar for moder), is that right? And what's the difference between them and (Far/Mor)?
Yes, that is right. "Fader" and "moder" are very rarely used at all. They sound old-fashioned and a bit solemn. The only use I can think of where you'd hear "fader" is when referring to God.
Is fäder pronounced "fader" or "feder"? The pronunciation is a bit confusing.
When the slow pronunciation is different than the fast pronounciation, which is better to follow/more accurate?
The sentence audio pronounces fäder as "fedder", but the individual word audio pronounces it as "fodder". Which is correct? I would think the first one.
