Is 'bolso' pocket but 'bolsa' handbag?
How do you set "her" and "your" apart?
Here they mean the same. Sometimes to set "her", "him" and "your" apart we use dela(her) and dele (his) after the noun. His car = o seu carro / o carro dele; her house: a sua casa / a casa dela.
Yes, that makes sense. Otherwise you don't know what you are talking about anymore. :)
Shouldn "O seu bolso" also be correct here?
i wrote handbag insted of bag... But it said that it was wrong, why?
Because it means ' pocket', perhaps?
