In German, adjectives change their endings depending on whether the person or thing you are referring to is masculine, feminine or neuter, and singular or plural. It also depends on the case of the person or thing you are describing and whether it is preceded by the definite or indefinite article.
German adjectives come before the noun they describe, but when used with a verb it is placed after the verb.
e.g.
Die alte Frau – the adjective ‘alte’ is before the noun ‘Frau’
Du bist schön – the adjective ‘schön’ is after the verb
Adjectives used after the definite article Der, Die and Das:
| Case | Masculine | Feminine | Neuter | Plural all Genders |
| Nominative | -e | -e | -e | -en |
| Accusative | -en | -e | -e | -en |
| Genitive | -en | -en | -en | -en |
| Dative | -en | -en | -en | -en |
