"Do you have your lunch?"
Translation:Hast du dein Mittagessen?
I was also having problems, in terms of when should I use "Ihr, euer, or dein" type of "your"?
At some point I stopped and did some research, and I've managed to build this handy table, that really helped me to get things right from there on:
Masc | Fem | Neu | Plu
Ihren | Ihre | Ihr | Ihre | for formal you, when you use Sie
euren | eure | euer | eure | for when you refer to a group of stuff (plural)
deinen | deine | dein | deine | for informal you (du)
This is the table that I organized for the accusative case. Hope it helps.
Neuter ein-words (ein, dein, kein, etc.) don't take -es endings except in the Genitive case. So it's "dein Mittagessen" instead of "deines." This site might help: http://marathonsprachen.com/adjective-endings-the-things-we-dont-hear/. And of course Wikipedia: http://en.wikipedia.org/wiki/German_articles
Thank you very much, that explains a lot.
So the different versions of 'Dein' 'Sie' 'Ihr' relate to the gender of the word preceding and following - as well as plural, Nom, Acc Dative uses? Does anyone have a simple explanation of how that works with particular reference to the word 'Your'? Thanks again!
That has declension tables for all of the possessive pronouns, including the different form of "your."
