Is learning Icelandic insanely difficult?
Is it crazy to even attempt it? I have studied a lot of languages but Icelandic grammar just makes me want to break down and cry.
Nothing is crazy to attempt, with enough motivation, materials and immersion, you can learn any language. Over 90% of Icelanders speak Icelandic, clearly it's possible.
Lindsay justifies the rating with the archaic vocabulary, high irregularity and some weird pronunciations. To put the ratings in context, both FSI and Lindsay put Icelandic as harder than German and modern Romance languages, as difficult as Polish and Greek, and easier than Mandarin.
Honestly it's only hard if you think it's hard. I know people who have learned Icelandic, yes they had to work extra hard, but for them it was worth it in the end. I never look at a language just on how hard or easy a language is because all languages have their hard aspects and their easy aspects.
Have possibly also a look at the http://langu.ag app.
160 natural languages, including Icelandic.
1 language free, $5 once for all 160 languages. Focus on vocabulary.
I tried Icelandic, and saw now more connection with e.g. the Germanic language Norwegian when seeing it written and spoken there in the app.
I know it's not exactly the same but I'm learning Old Norse at the moment. Icelandic's grammar has not changed very much at all since the Vikings spoke Old Norse and settled in Iceland. Like Mr_Eyl said, the case system is probably the most challenging part of it's grammar but it isn't exactly hard if you don't over think it. Once you learn the difference between the subject, direct object, indirect object, and the genitive nouns it gets easier from then on. I found, actually, that the case endings for words makes total sense to put into a language and now that I think of it English should have kept its case endings for its nouns.
If small children can do it, so could you! (That's what I'm hoping about "my" studied language anyway). I don't think your Swedish will be of much help though, and that's because I (fluent in Swedish) can barely read or understand any Icelandic, for example mbl.is the newspaper is very difficult for me.
I don't speak icelandic. My native tongue is scottish gaelic. I learned a few different languages with different grammar like dutch and Spanish. I feel that after getting used to people speaking it and repeating phrases you sort of get tbe feel for grammar. It may be strange at first but has a unique feel to the language. It might slowly start to make sense
