Common mistake: verb position in main vs subordinate clause – Telc B1

Main clause: Conjugated verb in second position (or first in questions). Ich habe das Buch gelesen. Gestern habe ich das Buch gelesen. Subordinate clause (weil, dass, wenn, obwohl, etc.): Conjugated verb at the end. ..., weil ich das Buch gelesen habe. A very common mistake is putting the verb in second position in the subordinate clause (weil ich habe das Buch gelesen – wrong).
