May I address you informally?
DAR-le del TU — 'darle' combines 'dare' + 'le' (to you, formal). Stress on each first syllable.
Ask before switching from formal 'Lei' to informal 'tu' with someone you've just met in a professional context. Always wait for permission or clear invitation before switching. In casual social contexts, 'tu' is often used immediately.
Italian has formal ('Lei') and informal ('tu') address forms. Using 'Lei' with strangers, older people, professionals and authority figures is standard. Younger Italians switch to 'tu' quickly in social contexts. In business, wait to be invited. The shift is called 'darsi del tu' — a significant social moment.
Diamoci del tu.
Let's use 'tu' with each other.
Mutual proposal — much warmer than asking permission.
Preferisce che la chiami con il 'lei'?
Do you prefer I address you formally?
Ultra-polite check — appropriate with elderly or very formal people.
Mi dia pure del tu.
Please feel free to use 'tu' with me.
Invitation from the other person — accept gratefully.
The shift from 'Lei' to 'tu' is a genuine social milestone in Italian relationships. Being invited to use 'tu' by an Italian signals acceptance and warmth. Forcing the switch without invitation can be seen as presumptuous — always wait.
