Can I help you?
Stress 'POSso' and 'aiuTARla' — the 'r' in aiutarla is a single tap, not rolled heavily.
Said by shop assistants when approaching a customer. Use this yourself when you want to offer help. In Italy, staff often approach quickly.
Uses the formal 'La' (object pronoun for Lei). 'Posso' is the first-person present of 'potere'. Formal register is standard in Italian shops, even small boutiques.
Posso aiutarti?
Can I help you? (informal)
Use with friends or in very casual shops
Ha bisogno di aiuto?
Do you need help?
Slightly more deferential, common in upscale stores
Cerca qualcosa in particolare?
Are you looking for something specific?
Opens the conversation more naturally
In Italian boutiques, staff greet you as soon as you enter. Unlike some cultures where browsing silently is expected, Italians appreciate a brief verbal exchange even if you just say 'Sto solo guardando'.
