Questions & Answers about Er hat viel Ausdauer, sodass er den Wettkampf gewinnt.
Could I split sodass and write so viel Ausdauer, dass... instead?
Yes! You could also write Er hat so viel Ausdauer, dass er den Wettkampf gewinnt. In that version, so emphasizes the amount of endurance in the main clause, and dass introduces the result. Both versions are grammatically correct and mean the same thing.
Why does the verb gewinnt go at the very end of the sentence?
Because sodass (so that) is a subordinating conjunction. It introduces a subordinate clause that describes the result or consequence of the main clause, and subordinating conjunctions always push the conjugated verb to the very end of their clause.
Why is it den Wettkampf and not der Wettkampf?
Wettkampf (competition) is a masculine noun (der Wettkampf). In this clause, it is the direct object being won, so it must take the accusative case. This changes the masculine article der to den.
Why does the sentence use the present tense gewinnt instead of the future tense?
In German, the present tense is very often used to talk about events happening in the future, as long as the context makes it logical. It can also describe a general fact (he always wins because of his endurance). You could use the future tense (...sodass er den Wettkampf gewinnen wird), but using the present tense is much more common and natural here.
