How to say "Exuse me" & "I'm sorry" in Polish.

Przepraszam is a magic word in the Polish language, because it's a very polite and very useful one. You can use it instead of an English expression "Excuse me", but also instead of English "I'm sorry". The meaning depends on the situation. Let's see some examples: 

You should say "Przepraszam", when you are going to interrupt someone and ask about something, for example when you are asking someone to show you the way.

When you are asking an unknown woman, say - "Przepraszam panią" (Excuse me, Madam). When you are asking an unknown man – you should say "Przepraszam pana" (Excuse me, Sir).When you are talking to a child or a friend you can use an informal expression 

"Przepraszam cię" or you can just say “przepraszam” and ask your question – “Przepraszam” without any other words which address your interlocutor sounds neutral and quite polite in Polish - so you can use that when you are talking to women and men, young and old people. 

Dialogue 1: - „Przepraszam panią! Gdzie jest ulica Bracka?”A (Excuse me, Madam! Where is Bracka Street?)

- "Bracka? O, tam na lewo." (Bracka? Oh, it's there - on the left.)

Another dialogue (without a picture): "Przepraszam Pana, gdzie jest ulica Mazowiecka?" (Excuse me, Sir? Where is Mazowiecka Street? Mazowiecka. It's there - on the right.

(Bracka and Mazowiecka are names of two quite famous streets in Warsaw).

The same way you can use a word "przepraszam" when you want to ask about other things - for example about a free seat on the plane, in the cinema etc.

The dialogue in the pictures:

- Przepraszam (bardzo)! Czy to miejsce jest wolne? (Excuse me, is this seat free?) 

- Tak, proszę bardzo! (Yes, please sit down).

"bardzo" - means literally "very", but with words "proszę" and "przepraszam" is used to make our requests even more polite.
