what's the difference between Mitt and Min? They are both translated to my/mine
You are correct. Also, Mina is the plural possessive of Jag. I suggest you look at the web version of Duolingo and not the app so that you can look at the notes; at least for the first lesson of each new skill. :)
The r is still there, only less pronounced than it would be at the end of a sentence or as a stand-alone word.
Is there an easier way of distinguishing between -ett and -en words because I am constantly getting these wrong because I don't know the difference. At the moment I am pretty much guessing??
Swedish doesn't have a continuous tense, so there's no difference between "is drinking" and "drinks" - they're both dricker. You can translate to either one throughout the course, and if you ever need to distinguish between them in a real-life situation, you can derive it contextually.
so there's no difference between "is drinking" and "drinks
And at least to my English-as-a-first mind that presents a dilemma if not a serious problem.
What am I to think if you say your dog drinks water. I'm pretty sure all dogs drink water and they love it. Are they drinking water right now? Okay now that's slightly different.
It's less of an issue than you might think at first glance. There are very few situations in which context doesn't make it abundantly clear, and there are other ways of expressing the continuous which you'll encounter later in the tree. :)
