The only google hit I can find (apart from this thread) is an FB post "En ulltant kräver sin Harris-tweedhatt", with a picture of a woman wearing a tweed hat, and various hashtags relating to Swedish wool. From that I am guessing it means "wool aunt", which possibly makes as much sense in Swedish as it does in English. An aunt, or aunt-like person, who likes wool, or who knits?
This seems to be just a compound noun, "ull" + "tant". I believe "tant" in Swedish does not necessarily mean "aunt", but rather "elderly or middle-aged female relative", or just "elderly or middle-aged woman". Maybe a Swedish speaker could confirm that?
Yes, we need context and preferably a source. While we are waiting for that, my guess would be that this is meant to describe a woman who uses wool for making handicraft products. It could be spinning and knitting, or feltmaking, or whatever you do with wool. But without more context, this is just a guess.
More like "elderly or middle-aged woman"... not necessarily a relative.
The combination of wool and "tant" doesn't necessarily immediately imply a clear meaning to me. Could be a woman who likes wool or it could maybe be a derogatory term for old ladies who like old-fashioned fabrics... I'm making this up without context.. it's not clear what its intended meaning is.
Hi everyone and thanks for your replies! Unfortunately there is no more context, a guy is just describing sheep shearing and he says that the neighbours always come to watch and the ulltanter come and children want to help and that's it. So I think it's probably the ladies from the village who like to knit who come to get some wool (while originally I thought it was maybe a part of some kind of an ancient village ritual but apparently not ).
