In German, is the conjugation for wir, sie (plural) and Sie (formal) always the same or are there exceptions? Do they also always match the infinitive? Examples:
| infinitive | 1st person plural | 3rd person plural | formal |
|---|---|---|---|
| essen | wir essen | sie essen | Sie essen |
| spielen | wir spielen | sie spielen | Sie spielen |
| geben | wir geben | sie geben | Sie geben |
I can't think of a verb that differs in conjugated form for wir, sie (plural) and Sie (formal).
However, be careful: they don't always match the infinitive form!
The examples you've listed match the infinitive in active present tense - but differ in passive (sie werden gegeben), or other tenses (wir/sie/Sie gaben).
There are other examples where the infinitive and active present tense don't match: sein - wir/sie/Sie sind.
