Questions & Answers about Die Stadt wurde am Fluss gegründet.
Why do we use wurde instead of war to say 'was founded'?
We use wurde (the simple past of werden) because this is an action passive. It focuses on the actual event of the city being established. If you used war (Die Stadt war gegründet), it would be a state passive, which just describes the condition of the city after the founding was already completely finished.
Why does gegründet go at the very end of the sentence?
In German passive sentences, the helping verb (wurde) and the past participle (gegründet) form a sentence bracket. The conjugated helping verb takes the standard second position, and the past participle is pushed all the way to the end of the clause.
Why is it am Fluss (dative) rather than an den Fluss (accusative)?
am is a contraction of an dem. The preposition an is a two-way preposition. Because the city was founded at a specific, fixed location (answering the question 'where?'), we use the dative case. If an action involved movement directing something toward the river (answering 'where to?'), we would use the accusative case.
Is the verb gründen related to the noun der Grund?
Yes! The verb gründen (to found or establish) shares its roots with the noun der Grund, which means the ground, foundation, or reason. When a city is founded, its groundwork is literally being laid.
