For me, when I was at the A2 level, it was a big mystery why, when we join the second parts of sentences with the same explanatory meaning, but different conjunctions (denn, weil, deshalb), the word order changes all the time. On the courses the teachers could not clearly explain this to me – you just have to remember. And I hate “just remember”, I prefer to understand. Therefore, we are looking for the answer ourselves.
It will be about conjunctions and connector adverbs, and for the sake of completeness, we will also take prepositions.
