Questions & Answers about Min cykel er grøn.
Because Danish possessive words agree with the thing possessed, not with the owner.
- min = used with a common-gender singular noun
- mit = used with a neuter singular noun
- mine = used with a plural noun
Cykel is a common-gender singular noun, so it takes min:
- min cykel = my bike
- mit hus = my house
- mine cykler = my bikes
Because min already functions as the determiner.
In Danish, you normally do not use an article together with a possessive like min:
- min cykel = correct
- en min cykel = incorrect
You also would not say min cyklen in standard Danish. The possessive replaces the article marking here.
