This topic German Akkusativ is a bit complex. Please have a look at the video.
Accusative is the form for the Object. In German, you have to differ between Subject (=Nominative Case) and Object.
Other languages (English, French, Spanish) have a fixed syntax: Subject – Verb – Object. That means, the subject is always at position 1.
In German, however, Object – Verb – Subject is possible as well. It is not common, but you have to understand that German does not mark the subject or object by its position, but by its case.
