German Grammar Explained /
Because
Conjunctions are those little words that connect two clauses.
Ich mag Kaffee und ich liebe Cappuccino.
Some conjunctions like weil (English: "because") introduce a subordinate clause. That means, a clause that cannot stand on its own because it wouldn't make much sense otherwise. Subclauses depend on the main clause to be coherent.
So what?
In German, when we have a subclause, we put the verb at the end of the sentence. Instead of saying: Ich komme nicht, weil ich habe keine Zeit.
We say...
Ich komme nicht, weil ich keine Zeit habe.
I won't come because I don't have time.
In a nutshell:
After you use weil, just put the conjugated verb at the very end of the sentence. Easy!
