German has a case system. This means that words, or the endings of words, have to change according to their function in a sentence.
There are four cases, and three of them affect pronouns:
Singular personal pronouns vary depending on the case.
|ich - I||mich - me||mir - me|
|du - you||dich - you||dir - you|
|er - he||ihn - him||ihm - him|
|sie - she||sie - her||ihr - her|
|es - it||es - it||ihm - it|

|Kennst du ihn?||Do you know him?||‘Him’ is the object of the verb kennen, so must be accusative.|
