Questions & Answers about Wir haben nicht bezahlt, weil ich die Kreditkarte vergessen hatte.
Why do we use the regular past (haben nicht bezahlt) in the first half, but the Past Perfect (vergessen hatte) in the second half?
This sets up a clear timeline. The Past Perfect (Plusquamperfekt) is used to show that an action happened before another action in the past. The forgetting happened before the moment they tried to pay, so it gets the hatte + past participle form.
Why are the verbs at the end in the order vergessen hatte instead of hatte vergessen?
The word weil (because) is a subordinating conjunction. It forces the conjugated verb to the very end of the clause. In the Past Perfect tense, the conjugated verb is the helper hatte, so it must go after the past participle vergessen.
How do I know whether to use hatte or war for the Past Perfect of vergessen?
You use the exact same helper verb you would use for the regular Present Perfect tense. Because vergessen (to forget) takes a direct object (the credit card), it uses haben. To make it Past Perfect, you just change haben to its simple past form, hatte.
Wait, is vergessen the infinitive or the past participle here? Why is there no ge- at the beginning?
It is the past participle! Verbs that start with inseparable prefixes like ver-, be-, or ent- do not get a ge- added to them in the past participle. For vergessen, the infinitive and the past participle happen to look exactly the same.
