Use of ''Meiner'' in sentences and how it works
was just wondering the use of ''meiner'' in replacing mein or meine. i know mein is masc and meine is fem, but not sure the use of just ''meiner''. i do frequently see it used as ''meiner schwester'' in sentences though. can someone please explain this to me.
Well, you can use "meiner" not not only for a dative or genitive case.
Ich gebe das Buch meiner Schwester.
Das ist das Buch meiner Mutter.
You would use it after a question too.
A: Wem gehört der Hund?
B: Das ist meiner!
All pronouns adapt to the cases in which the nouns they are referring to are placed.
A: Ich habe einen Ball und du?
B: Meiner ist kaputt.
No, you really WOULDN'T (couldn't, shouldn't) say it like that. In German, you don't give a book TO someone but you 'give a book someone' (the 'to' is not needed or translated from English to German and the 'directional' is already included in the word order of subject TO object). Thus, in (high/ written) German you would say 'Ich gebe das Buch meiner Schwester' rather than 'Ich gebe das Buch zu meiner Schwester'. That is different for 'bringen' -- for the word 'bring', you can either bring something someone or bring something TO someone in German.
