>>686889Well Duolingo has categories, which are split into lessons, and I do 5 lessons per day minimum. It takes about a quarter of an hour to do, maybe a bit more if the lesson is hard. You also have to "strengthen" categories you've completed from time to time, and the more you go, the more categories you've completed, so the more time it takes. Such an act gives you the equivalent of 1 lesson, and it takes much more time.
Syntax is a bit weird sometimes, and there are verbs which change meaning when followed by a certain particle. For example, "jag tycker om dig" means I like you, but "jag tycker på dig" means I think of you if I'm not mistaken.
One big difficulty is the "en/ett" difference. Some words are "en" words, while others are "ett" words. If you want to say "an apple", you'd say "ett äpple", because it's an "ett" word (for "the apple" you'd say "äpplet"). If you want to say "a man" you'd say "en man" because it's an "en" word (for "the man" you'd say "mannen").
Other than that, it's pretty chill. Verbs are pretty standardized, there's only about 30% of the verbs I've learned that didn't follow the rules, grammar is easy as well, it's not a case language so that's always a plus.
