I'm a beginner in German, and I don't quite understand when to use "nicht."
I understand that "nicht" is the negation for verbs and adjectives, while "kein" is for nouns.
Roughly translated to English, I would say that nicht = not, while kein = no.
So, one could say, "Ich bin nicht traurig," and "Ich bin keine Ärztin."
But how would one use "nicht" in a sentence with more than one verb. I was told that if there were two verbs, you would negate the second verb.
So one would say, "Ich kann das nicht verstanden," instead of "Ich kann nicht das verstanden."
But how would you use "nicht" in a sentence with more than two verbs?
And what about sentences like "I cannot play football." Would you say, "Ich kann nicht Fußball spielen," or "Ich kann Fußball nicht spielen"?
And does one use "nicht" or "kein" in sentences like "I am not Barack Obama"?
Vielen Dank für eure Hilfe.
