I'm looking for friends! Letar jag efter vänner! Szukam kolega/koleżanka!
Hello! I'm looking for somebody who would be willing to learn/practise Swedish and/or Polish with me. I'm a minor that's a native speaker of English. Thanks so much!
Have a look at this post about how to find language exchange partners: https://www.duolingo.com/comment/1444346. There are links to some useful websites on there. Don't miss DamedesLangues's comment, which has links to more sites.
It's also worth looking on the Multilingual learning resources page on the wiki.
Actually that was singular, just changing the case to match the verb "szukać". It needs Genitive, and Genitive from "kolega" and "koleżanka" are "kolegi" and "koleżanki".
Nominative plurals of these words are "koledzy" and "koleżanki", so when using Genitive because of "szukam" it would be "Szukam kolegów/koleżanek".
I'm learning both languages too. I'd say my Swedish is significantly better than my progress here would suggest because I live in Sweden and speak it often but just don't practice here that much. My Polish is pretty basic still.
They're very different in a lot of ways, so I find that they don't really interfere with one another. Swedish is Germanic, has no cases other than a few relics in different forms of pronouns, does not conjugate verbs for person or number, is a pitch accent language, distinguishes between definite and indefinite in both single and plural, etc., whereas Polish is Slavic, has a complex case system, has somewhat more complex verb conjugation, doesn't have any articles, and has very, very different pronunciation and no pitch accent. If you're a native English speaker I think you will find Swedish far easier due to the similarities. If it were not for the damned pronunciation, it would be easy as pie for me because I speak German fluently as well.
You will find the occasional cognate thanks to shared Germanic, Latin or Proto-Indo-European roots, but they otherwise have little to do with one another and I don't think learning them at the same time will either help or hurt (other than the obvious effects of splitting your time between two things).
