Accusative or nominative
Itâ€™s very important to correctly distinguish between accusative and nominative cases. These two cases tell us which noun is the actor, and which is being acted upon.
To determine whether something is nominative or accusative, ask yourself if the noun in question is a doer. Unless you are working with passive sentences, the doer is always in the nominative case. Also, itâ€™s usually safe to assume in English and in German that the first noun in the sentence is the subject, and thus requires nominative case markings.
The following exercises will test your ability to distinguish between and use nominative and accusative case markers together.
