Questions & Answers about Wir danken dem Mentor für seine unersetzliche Weisheit.
Why do we use the dative dem Mentor instead of the accusative den Mentor?
The verb danken is a dative verb. In German, you do not thank a direct object; you give thanks to someone as an indirect object. Therefore, the person being thanked must always be in the dative case.
What case is seine unersetzliche Weisheit, and why?
It is in the accusative case. This is governed by the preposition für, which always forces the following noun phrase into the accusative. This creates the very common structure jemandem für etwas danken (to thank someone for something).
Why does the adjective unersetzliche end in -e here?
It follows the rules for mixed adjective declension. Because of für, the phrase is accusative. The noun Weisheit is feminine, so after the possessive determiner seine, the feminine accusative adjective takes the standard -e ending.
How is the adjective unersetzliche built from its root?
It comes from the verb ersetzen (to replace). Adding the suffix -lich creates the adjective ersetzlich (replaceable), and the prefix un- negates it to mean irreplaceable.
Is there a reliable rule to remember that Weisheit is feminine?
Yes! Any German noun ending in the suffix -heit (as well as its close relative -keit) is absolutely always feminine.
