Hello! Today, we'll explore a very important German grammar rule: verb placement in subordinate clauses (Nebensatz). Remember, a subordinate clause is a dependent clause that completes the main clause.
Normally, in German, the verb comes in the second position. However, in subordinate clauses, the verb always moves to the very end of the sentence. This rule applies when conjunctions such as weil (because), dass (that), or wenn (if/when) are used.
For example, compare the main clause: "Ich lerne Deutsch." (I learn German.) with the subordinate clause: "Ich lerne Deutsch, weil es wichtig ist." (I learn German because it is important.) As you can see, ist (the form of 'to be') shifts to the end. Remember this: in a subordinate clause introduced by a conjunction, the verb is always last. Practice will make it easy!
