- I try to actively write something and when I hit a wall, I try in other languages: the important in this part is to get the text flowing from me. Eg, "du could har hjælpe mig, når jeg called du" (trying to write in Danish, "you could have helped me when I called you")
- I then paste it on ChatGPT and ask for a C2-level correction with explanations on vocabulary and grammar, and translations into a few other languages. Eg, my prompt would be """ "du could har hjælpe mig, når jeg called du"
correct to c2-level and explain grammar and vocabulary. give related examples. then translate to German, English, French and Italian. """
This is incredibly helpful to do everyday, especially if you are also learning passively by reading/studying by yourself. By the way, for those curious, here's how ChatGPT would correct the sentence: "Du kunne have hjulpet mig, da jeg ringede til dig." Interestingly, it assumed I meant "called" as in, "telephoned" (not my original intention). Translating into other languages helps you spot and get a sensibility for such cases.
As an aside, for me the most challenging part of learning Danish is the pronunciation. It's beautiful, but it doesn't map out too easily to written words :)
