RULES FOR DEPENDENT CLAUSES

A dependent clause is one that won't stand alone. For example: "Since I am sick"

In a dependent clause, the verb is always at the end.

I am sick (not dependent) : Ich bin krank.

Since I am sick (dependent): Weil ich krank bin.

When a dependent clause appears in a sentence it may go first or last.

If the independent clause comes first, the word order is as it is in a normal sentence:

I am not going to the park today since I am sick. Ich gehe heute nicht in den Park, weil ich krank bin.

If the dependent clause goes first, then the word order in the independent clause must be reversed.

Weil ich krank bin, gehe ich heute nicht in den Park.

RULES FOR MODAL AUXILIARIES

The modal auxiliaries are:

können	dürfen
mögen	müssen
wollen	sollen

Modal auxiliaries do not add "t" for the 3rd person singular:

kann	darf
muss	mag
will	soll

When a modal auxiliary occurs, the main verb moves to the end of the clause.

I want to go home: Ich will nach Hause gehen

GENERAL RULES FOR FORMING THE PAST PARTICIPLE

1. Some verbs occur with "haben" others with "sein". Both act the same way modal auxiliaries do. They occur next to the subject and the main verb moves to the end.
