Okay so we've experienced two different types of inversions throughout the conjunctions skill? One related directly to subordinating conjunctions and the other to sentence structure?
For example would "Omdat ik boeken heb, lees ik." be correct? Since "omdat" is subordinating you move the verb "hebben" to the end of that clause. And then since the clause "ik lees" is not at the beginning of the sentence, you have to invert it. But you could also say "Ik lees, omdat ik boeken heb?"
Please tell me if I am understanding this correctly!
