"We live in our home."
Translation:हम अपने घर में रहते हैं ।
Not 'hamare' because we start the sentence with 'ham'. So instead we put 'apne' to avoid redundance. So not: "main mere ghar me..." but --> main apne ghar... Not: "tum tere ghar me..." but --> tum apne ghar me...
apna - for masculine singular objects; apni - for female singular or plural objects; apne - for masculine plural objects (and it seems that also for 'oblique case')
