Questions & Answers about Hast du den Platz für mich reserviert?
Why is the past participle reserviert instead of gereserviert?
This is because the verb reservieren ends in -ieren. In German, verbs with this ending do not take the ge- prefix when forming the past participle. You just drop the -en and add a -t.
Why is it den Platz instead of der Platz?
Platz is the direct object of the sentence, meaning it is the thing being reserved. This puts it in the accusative case. Because Platz is a masculine noun (der Platz), the article changes to den in the accusative.
Why is the word reserviert at the very end of the sentence?
In the German past tense (the Perfekt), the two parts of the verb separate. The helping verb (here, hast) takes the first position to form a yes/no question, and the past participle (reserviert) is pushed to the very end of the sentence.
Why does the sentence use mich instead of mir after für?
The preposition für (for) always requires the accusative case for the noun or pronoun that follows it. The accusative form of ich (I) is mich (me).
