Can anyone explain me the genitive case better?
I've got which articles I have to use but I haven't got how the other words change at the end
I'm not a native speaker but here's what i understand of the genitive case endings:
In the singular:
-neuter nouns take the -ου ending
-ος becomes -ου
-ης/-ες become -η/-ε (masculine)
-η/-α become -ης/-ας (feminine)
In the plural: all nouns take the -ων ending
Neuter -ου: true for neuters in -ο and -ι.
Neuters in -μα turn into -ματος (e.g. του μαθήματος "of the lesson").
