Een koe is een vrije koe!
I find the placements of 'geen' or 'niet' very confusing. I thought here that is 'een koe is niet...' for sure, but apparently not.
"Geen" is usually used as a translations of the English "not a(n)" or "no". There is a longer explanation here.
Thank you very much! Very helpful link!
That's a moo point
Ok then ¯_(ツ)_/¯
When will cijfer be used? Is it for being formal?
