I thought the position of the subject in a sentece had only three different position:
- The first word on the sentence. This is by far the most popular one.
Ich habe einen Hund
- Inversion of subject. This is done to give emphasis to another word, and the subject takes the 3rd position
Einen Hund habe ich
- Question. In this case it takes the third position.
Hast du einen Hund?
But today I heard a sentence that did not follow any of these rules.
Schließlich helfen ihm seine Freunde.
In this case it takes the fourth position. Is this really allowed? Am I missing a rule for position of the subject?
