Questions & Answers about Heute Abend gehe ich mit meiner Freundin aus.
In German main clauses, the conjugated verb must be in second position (the “V2 rule”).
Here, Heute Abend (Today/This evening) is put in first position for emphasis, so the verb gehe has to come second, and the subject ich comes after it:
- Heute Abend (1st position) gehe (2nd) ich (3rd) …
If you don’t move anything to the front, you get the more “neutral” order: Ich gehe heute Abend mit meiner Freundin aus.
Yes, that sentence is completely correct and very common.
- Ich gehe heute Abend … is a neutral word order.
- Heute Abend gehe ich … puts a bit more emphasis on when you’re going out, similar to English: “This evening I’m going out with my girlfriend.”
Both are natural; Germans use both all the time.
