Thanks everyone!
Thomas,
For number 2 the context is "Going to this store is a possibility."
Ok then, I think I'd say something more or less along these lines:
Możliwe (jest), że pójdziemy do tego sklepu. (
pójdziemy-1st person plural from
pójść)
You can also say:
Pójście do tego sklepu jest możliwe. (which is a more verbatim translaton of your phrase.
And for #3, my relatives use a different word for wallet that sounds like "portmonetka". He is talking about his wallet. Is there such a word and is there a difference between a woman's wallet and a man's wallet?
Dzękuję,
Drei
Where I live there used to be division:
portmonetka--coin purse (porte-monnaie if you know French), I saw portmonetki-used rather by women where you can keep banknotes as well and they do look more feminine to me
portfel-can be used by both men and women--wallet (portefeuille)
These differences are very much blurred nowadays and some people probably don't know about them using both terms interchangeably, I don't.
In your sentence you can use either of them.
Tom
