Questions & Answers about Wir essen heute Hähnchen.
Because the subject is wir = we.
The verb essen is conjugated like this in the present tense:
- ich esse
- du isst
- er/sie/es isst
- wir essen
- ihr esst
- sie/Sie essen
So with wir, the correct form is essen.
In a normal German main clause, the finite verb comes in second position. That is one of the most important word-order rules in German.
So in:
Wir essen heute Hähnchen.
- Wir = first position
- essen = second position
- heute = later in the sentence
This is a very natural, neutral word order.
You can also say:
Heute essen wir Hähnchen.
That is also correct, but now heute is being emphasized a bit more.
