Short Answer
In Italian, “tu” is the informal second‑person singular pronoun, while “lei” is the formal second‑person singular pronoun used to show respect.
Literal Translation & Pronunciation
tu – literally “you” (informal). lei – literally “she”, now used as “you” (formal).
IPA: /tu/ for “tu”; /ˈlɛi/ for “lei”.
Origin & Etymology
The pronoun tu descends directly from Latin tu, the second‑person singular pronoun used both socially and grammatically. Lei originates from the Latin demonstrative illa (“that one”), which evolved into the third‑person feminine pronoun lei in early Italian; its polite function emerged in the 16th‑17th centuries under Spanish courtly influence, mirroring the French vous and the German Sie.
How It’s Used in Context
Italian: Tu sei il benvenuto.
English: You are welcome. (informal)
Italian: Lei desidera qualcosa?
English: Do you desire something? (formal)
Italian: Se vuoi, possiamo andare al cinema.

Regional Variations
- In Sicily, “tu” is often used even with acquaintances, while “lei” can sound overly distant.
- In Veneto, the historic form “voialtri” has faded; today “tu” and “lei” follow the national standard.
- In Naples, “vuie” (plural) is used informally among peers, whereas “lei” remains the polite singular.
- Sardinia retains the form “bos” for formal address, especially in rural contexts.
- Several northern dialects historically used “voi” as a singular polite form, a usage now largely literary.
Common Mistakes / What It Doesn’t Mean
Do not confuse “lei” with the literal meaning “she”. In contemporary Italian, when capitalised or preceded by a verb, “Lei” functions solely as a polite second‑person pronoun. Using “tu” with elders, superiors, or strangers without consent can be perceived as disrespectful.

FAQ
Is it rude to use ‘tu’ with someone I just met?
Yes, unless the speaker explicitly invites you to use ‘tu’. In most professional or first‑meeting contexts, ‘lei’ is the safe default.
When should I switch from ‘lei’ to ‘tu’ in a professional setting?
A common practice is to wait for the senior party to suggest “passiamo al tu”. In written emails, you can ask politely: “Posso usare il ‘tu’?”
Does ‘lei’ ever mean ‘she’ in modern Italian?
Only when it appears in a third‑person context or is not capitalised. In spoken and written address, capitalised ‘Lei’ functions solely as the formal second‑person pronoun.
