Revision: declension of the possessive determiner

The ending of the possessive determiner in the singular is identical to the ending of the indefinite article:

• In the nominative and accusative, the possessive determiner takes the ending -e when it comes before a feminine noun or a plural noun.
• In the accusative, the possessive determiner takes the ending -en when it comes before a masculine noun.

Personal pronoun: ich
Possessive determiner: mein

masculine:
mein Bruder (Nominative)
meinen Bruder (Accusative)

feminine:
meine Schwester (Nominative and Accusative)

neuter:
mein Kind (Nominative and Accusative)

plural:
meine Eltern (Nominative and Accusative)
 

Personal pronoun: ihr
Possessive determiner: euer

Pay attention to the irregular form of euer and the ending:

masculine:
euer Bruder (Nominative)
euren Bruder (Accusative)

feminine:
eure Schwester (Nominative and Accusative)

neuter:
euer Kind (Nominative and Accusative)

plural:
eure Eltern (Nominative and Accusative)
