Sorry, excuse me, pardon!

[gabrigabri]

Hi!
Could please someone tell me what is the difference between (among???) those words?
Can I always use them, or is there a "right moment"?
Thank you!!

Ciao!
Qualcuno mi spiegherebbe la differenza tra queste parole e quando usare una e quando l'altra??
Grazie!

Pardon is quite formal.
Excuse me fits with formal or more relaxed situations
Sorry is quite informal.

I beg your pardon/pardon /excuse me /sorry ? can be for when you want the person to repeat what they said.
I beg your pardon, pardon me, excuse me /sorry can also be forms of apology.

Thanks!
So, if I want to go, but someone stays in front of me, so that I can't go, what can I tell him? Sorry, pardon and excuse me?
Or just to get his attention?

In that context I would say "excuse me" or "pardon me".

If you step on his foot as you pass him, then you could say sorry or excuse me, or I beg your pardon.

To get someone's attention I suggest "excuse me".
