The number of grammatical genders in Norwegian is somewhat disputed, but the official view is that Norwegian nouns fall into three genders: masculine, feminine and neuter. The inflection of the nouns depends on the gender.
Bokmål| m.: | en gutt | gutten | gutter | guttene |
| (a boy) | (the boy) | (boys) | (the boys) | |
| f.: | en/ei dør | døren/døra | dører | dørene |
| (a door) | (the door) | (doors) | (the doors) | |
| n.: | et hus | huset | hus | husene/husa |
| (a house) | (the house) | (houses) | (the houses) |
Note that feminine nouns can be inflected like masculine nouns in Bokmål. Riksmål rejects the feminine gender and merges it with the masculine into a common gender (utrum), like in Danish.
