Possessives in the Accusative

When a possessive comes before a direct object (after verbs like haben, sehen, suchen, besuchen, lieben, vergessen), it takes the accusative ending. Only the masculine form changes; feminine, neuter and plural look exactly like the nominative:

• masculine: meinen, deinen, seinen, ihren, unseren, euren (Ich rufe meinen Bruder an. = I call my brother.)
• feminine: meine, deine, seine, ihre, unsere, eure
• neuter: mein, dein, sein, ihr, unser, euer with no ending
• plural: meine, deine, seine, ihre, unsere, eure

euer drops its second e as soon as an ending is added: eure, euren. Use sein when the owner is masculine or neuter (er, es) and ihr when the owner is feminine or plural (sie).
