So if I want to say "I like my aunts and uncles." and I think of all of my aunts and uncles from father and mother side then should I really say: "Jag tycker om mina fastrar, mostrar, farbrödrar och morbrödrar."?
I know this is several months old, but it would be:
"Jag gillar alla mina föräldrars syskon," as in "I like all my parent's siblings."
And in case you're wondering gilla and tycka om are interchangeable, although I think gilla is slightly more informal.
Is there a term for 'aunt' without it being necessarily paternal or maternal?
No. Just like the words for grandparents, it's always specific. The same goes for uncle (farbror/morbror).
If you do not know which side of the family they come from, what would you say? Also, is it considered rude to forget if it is, for example, farbror or morbror?
No, it is not considered rude to make this mistake about farbror/morbror and faster/moster. It is not an unusual mistake. But may be you will be corrected (often with a smile). If you do not know which, the best thing is to ask.
I'm guessing it's just...natural to remember? Because in Chinese families we think of the two 'types' of uncles/aunts as completely distinct relatives.
There is "tant" which comes from French "Tante". But it's used mainly about any older woman (often derogatory). Actually I wish there was a similar way of referring to relatives in English, it would be less awkward than saying "maternal aunt" or "paternal grandmother" etc.
Is there a word for the spouse of a parent's sibling? Would, for example, my mom's sister's husband be called morbror and my dad's sister's wife be my faster?
No, usually some other construction like "famors syster" or "mammas moster".
Figuring out the right words for paternal and maternal aunts and uncles isn't actually that confusing if one analyze the words.
Farbror = far + bror ("father's brother") Morbror = mor + bror ("Mother's brother") Moster = mor + (sy)ster ("mother's sister") Faster = far + (sy)ster ("father's sister")
Would it be appropriate to translate this as "I have several aunts on my father's side" and/or "I have several paternal aunts."
In many english speaking cultures we use aunt and uncle to refer to family friends that we arent particularly close with ourselves (especially if we're young) or someone we should respect. Does this also go in Swedish with Swedish culture?
Well kind of, for example a child can say "Jag tycker inte om den där farbrorn. Han är en dum farbror." = I do not like that man. He is a stupid man. A grownup would probably use "mannen" eller "karln" instead of farbrorn. But sometimes even grownup can use it, but mostly its when we talk to children, I think.
Same with "tanten". You could use "tanten"/"tant" instead of farbrorn/farbror in the sentence abowe. More used with children to refer to an older women. But I could say that girl has really turned into a old lady = "Den där tjejen har verkligen blivit en tant".
But you don't use faster/moster instead of tant. But you could use "gubben/gubbe" instead of "farbrorn/farbror".
Hope this helped some!
How are uncles and aunts generally referred to? In Spanish you could say "mis tíos" speaking about all of one's parents' siblings. What do you use in Swedish?
As bloody_nubs (sort of) explained above, you would more likely just refer to them as "pappas/mammas syskon" ("dad's/mum's siblings") instead since "fastrar/mostrar och farbröder/morbröder" is a bit unwieldy.
