Lei / tu
Formal vs. Informal Register (Lei vs. Tu)
Italian uses two ways to say 'you' in the singular: tu for people you know well and Lei for people you don't know or want to show respect to. Using the wrong one can sound rude or overly cold.
How It Works
In Italian, choosing the right register is essential for social harmony.
1. The Informal Register (tu):
Used with friends, family, children, and peers. It uses the second-person singular verb forms (e.g., tu sei).
2. The Formal Register (Lei):
Used with strangers, elders, or in professional settings. You use the third-person singular (the 'she' form). In writing, it is often capitalized (Lei) to distinguish it from lei (she).
- Verb Agreement: Always third-person singular (e.g., Lei è).
- Adjective Agreement: Adjectives match the actual gender of the person (e.g., Lei è stanco, signore).
- Possessives: Use Suo, Sua, Suoi, Sue to mean 'your'. These agree with the object owned, not the person (e.g., il Suo libro).
- Object Pronouns: Use La (direct) and Le (indirect). Note that with La, the past participle usually takes a feminine ending: L'ho conosciuta, signore.
3. Addressing Groups (Plural):
In modern Italian, voi is the standard plural for both formal and informal situations. While Loro exists as a strictly formal plural, it is now considered very archaic and is rarely used outside of extremely high-level ceremonies or luxury service.
4. Social Rituals:
Always start with Lei unless invited otherwise. The transition to informal is called darsi del tu. Usually, the person in a higher position will suggest: 'Possiamo darci del tu?'
Examples (5)
- Buongiorno, è questo il Suo ufficio?
Good morning, is this your office? (Formal)
Word by Word: Good day, is this the your office?
Uses the formal possessive Suo to mean 'your' when addressing one person formally.
- Signore, L'ho vista ieri in centro.
Sir, I saw you yesterday downtown. (Formal)
Word by Word: Sir, [I] you have seen yesterday in center.
When using the formal direct object pronoun La, the past participle often ends in '-a' even when addressing a man.
- Signori, voi siete pronti per l'ordine?
Gentlemen, are you ready to order? (Formal Plural)
Word by Word: Gentlemen, you are ready for the order?
In modern Italian, voi is used as the plural for both formal and informal address.
- Scusi, Le posso fare una domanda?
Excuse me, may I ask you a question? (Formal)
Word by Word: Excuse [me], to you [I] can make a question?
Uses the formal indirect pronoun Le and the formal imperative Scusi.
- Scusa, ti posso fare una domanda?
Excuse me, can I ask you a question? (Informal)
Word by Word: Excuse [me], to you [I] can make a question?
Uses the informal pronoun ti and the informal imperative Scusa.
Common Mistakes
Mixing registers in the same sentence.
Scusi, mi dai il sale?Scusi, mi dà il sale?If you start with the formal 'Scusi' (Excuse me), you must continue with the third-person verb 'dà' instead of the informal 'dai'.
Using second-person verbs with 'Lei'.
Lei sei molto gentile.Lei è molto gentile.Even though you are talking to 'you', the pronoun 'Lei' requires the third-person verb 'è' (is), not 'sei' (are).
Using 'voi' as a formal singular 'you'.
Voi siete molto bravo, professore.Lei è molto bravo, professore.While 'voi' is used as a formal singular in some Southern dialects or old literature, 'Lei' is the standard formal singular in modern Italian.
