In Danish the adjectives decline according to the gender and number of the nouns and to the definiteness of the nouns. Regular adjectives either have no ending, end on -t or end on -e: No ending for nouns with the article en, -t ending for et nouns and -e ending for plural and for known form of noun plus adjective.
| En words - no ending | en rød næse | næsen er rød, min næse er rød |
| Et words -t ending | et rødt øre | øret er rødt, mit øre er rødt |
| Plural -e ending | røde næser; røde ører | næserne er røde, mine ører er røde |
| Known form -e ending | den røde næse; mit røde øre; | Peters røde ører; børnenes røde næser |
Known form of noun plus adjective is always composed as a sandwich: First comes a definer: den/det/de/min/ Peters .... then comes the adjective ending on -e and then the noun.
