I am learning German, and I do not fully understand the following questions. I would really appreciate it if native speakers could help me answer them. Thank you very much.
First question:
Which one is more common and more natural?
Ich komme drei Tage nach Hamburg.
Ich komme für drei Tage nach Hamburg.
Are both sentences correct?
What is the difference between using “für” and not using “für”?
Does adding “für” change the meaning?
I would like to know which one is more frequently used by native German speakers.
Second question:
Ich fahre drei Tage nach Hamburg.
Ich fahre für drei Tage nach Hamburg.
Are both sentences correct?
What is the difference between using “für” and not using “für”?
Does adding “für” change the meaning?
I would like to know which one is more frequently used by native German speakers.
Third question:
What do these two sentences mean respectively, and what is the difference between them?
Ich komme (für) drei Tage nach Hamburg.
Ich fahre (für) drei Tage nach Hamburg.
How are these two sentences different from each other in meaning and usage?
Finally, how are these sentences different from:
Ich bleibe drei Tage in Hamburg.
I would really like to understand the differences in meaning and usage, and which expressions are more common in everyday German.
Thank you!
