Questions & Answers about Wann hat dein Wecker geklingelt?
How is the past participle geklingelt formed?
The infinitive is klingeln (to ring). Because it is a regular (weak) verb, we form the past participle by adding the prefix ge- and the ending -t to the verb stem (klingel). That gives us ge-klingel-t (geklingelt). Unlike the separable verbs you are learning in this lesson, klingeln does not have an attached prefix, so the ge- simply goes right at the beginning.
Why is geklingelt at the very end of the sentence?
In German, the spoken past tense (the Perfekt) uses a helping verb in the normal verb position and pushes the past participle to the very end of the sentence. Here, the helping verb hat takes the second position (right after the question word Wann), and the main action word geklingelt waits at the end.
Why does the sentence use dein Wecker instead of deinen Wecker?
Wecker (alarm clock) is a masculine noun. In this sentence, the alarm clock is the subject—it is the thing doing the ringing. Therefore, it stays in the nominative case (dein). If you were doing something to the alarm clock, like buying it or turning it off, it would be the direct object and would take the accusative case (deinen).
Could I use wenn instead of wann here?
