Goodbye! (formal)
'Arrivederci' — ar-ri-ve-DER-ci. Six syllables, stress on the fourth. The 'ci' sounds like 'chi'. Common mistake: saying 'arrivederla' (ultra-formal) unnecessarily.
Use with strangers, shopkeepers, service professionals, acquaintances, and in any situation where you want to be polite but not overly familiar. The standard formal goodbye.
'Arrivederci' means 'until we see each other again' — 'a rivederci' (until seeing each other again). It's the most versatile formal goodbye in Italian, suitable for all professional and formal contexts. Unlike English 'goodbye' (which has a one-size-fits-all register), Italian distinguishes formal from informal goodbyes.
Arrivederla!
Goodbye! (very formal, Lei form)
Ultra-formal — uses 'Lei' instead of 'ci'. Use with elderly strangers or in very formal professional settings.
A presto!
See you soon!
Slightly less formal — implies you'll meet again soon. Warm but still polite.
Buona giornata!
Have a good day!
Added warmth to the goodbye — often combined with 'arrivederci' in shops and offices
In Italian shops and offices, a departure is almost always marked by an exchange of goodbyes between customer and staff. Walking out silently without saying 'arrivederci' is considered rude — the goodbye ritual is part of the social compact of Italian public life.
