A little very useful tip to everyone, use social media (ex facebook twitter) in swedish, you will learn all the words in this unit subconciously from daily usage.
One of my Facebook friends lives in Sweden and it's such positive feedback to be able to read some of the posts and comments that are in Swedish.
Changing websites to your target language is a great way to learn words naturally, I think. In the modern age, we all encounter words that we wouldn't see in other contexts like "like" in the facebook context, or words like "tweet" (the verb and the noun), and then there's also the way that words develop new meanings on the internet. I think learning those by exposure on the internet is great, because it's one of the few categories of words that you can learn (or learn new meanings for) in the same way as most native speakers do.
I changed my phone primary language to Swedish. In Google Nyheter app I get Swedish news. Google Maps Navigation gives voice directions in Swedish (which confuses my wife). And finally Google Assistant speaks and listens in Swedish! Search request "metro preobrazhenskaya ploshchad" (preobrazhensky torget tunnelbanna station) it recognized as "min bror arbetar som skräppost"...
Would make a case for "Leave a comment!" as "Write a comment!" is a much less common imperative.
That would strictly speaking be lämna en kommentar in Swedish though (which is also a perfectly valid sentence).
What is difference between "Skriv en kommentar" and "Skriva en kommentar"? Or does the latter even exist?
