The rule: italian formal Lei in one line
Italian formal Lei addresses one person you don’t know well: someone older, a customer, a professional. Lei is third person singular feminine. Verbs go in the third singular form (come sta?), object pronouns are la, le, si, possessives are Suo, Sua, Suoi, Sue.
The plural counterpart in modern italian is voi, even when speaking to a group of strangers. The historical Loro (third plural formal) survives in hyper-formal restaurant service, royalty, and old-fashioned writing. Italian formal Lei is the everyday backbone of polite address.
When to use Lei vs tu
Default to Lei in any uncertain context: with strangers, professionals, customers, older people. Use tu with family, close friends, peers under 25-30, and people who explicitly invited you to switch. When in doubt, Lei is the safer choice for non-natives.
🔍 When Lei is mandatory:
- First contact with a stranger over 25 in any context: hotel, doctor, lawyer, official.
- Customer service: shopkeeper to customer, waiter to diner, hotel to guest.
- Professional context: client meeting, medical visit, banking, official documents.
- Older person you don’t know personally: neighbour you’ve never spoken to, elderly stranger.
- Written formal email to anyone you address as Mr/Ms/Dr/Professor.
🔍 When tu is normal:
- Family, close friends, classmates, romantic partner.
- Children and teenagers (always tu, regardless of speaker’s age).
- Peers under 25-30 in informal settings (bar, gym, sports team).
- After explicit invitation: diamoci del tu, puoi darmi del tu.
🎯 Mini-Challenge: Lei or tu?
- 1. You meet a 50-year-old doctor for the first time. Lei or tu?
- 2. You’re at the gym chatting with a 22-year-old. Lei or tu?
- 3. You’re writing a formal email to a hotel reception. Lei or tu?
Show answers
- Lei (stranger, professional, older).
- Tu (peer, casual setting, under 25).
- Lei (formal email, customer-business).

Pronouns and possessives with Lei
Lei takes feminine third-singular pronouns regardless of the addressee’s actual sex: direct object la (la chiamo, I’ll call you), indirect object le (le ho mandato un’email, I sent you an email), reflexive si (si accomodi, please sit), possessives Suo, Sua, Suoi, Sue (often capitalised in formal writing). Adjectives and past participles, however, agree with the addressee’s actual sex.
🔍 Pronouns and possessives:
- La chiamo io domani mattina. I’ll call you tomorrow morning. (direct object, even for a man)
- Le ho mandato i documenti via email. I sent you the documents by email. (indirect object)
- Mi dia il Suo indirizzo, per favore. Give me your address, please. (possessive)
- Lei e contento del servizio? Are you happy with the service? (to a man: contento)
- Lei e contenta del servizio? Are you happy with the service? (to a woman: contenta)
- Si e accomodato, dottore? Have you taken a seat, doctor? (male doctor)
- Si e accomodata, dottoressa? Have you taken a seat, doctor? (female doctor)
🎯 Mini-Challenge: pronouns + agreement

Switching: Diamoci del tu
The shift from Lei to tu is a small but important moment in italian relationships. The traditional formula is diamoci del tu (let’s call each other tu) or possiamo darci del tu? (can we use tu?). The proposal usually comes from the older or more senior person. Once accepted, both parties switch immediately: forgetting and going back to Lei after the shift sounds awkward.
🔍 The switch in action:
- Diamoci del tu, e piu comodo. Let’s call each other tu, it’s easier.
- Possiamo darci del tu? Can we use tu?
- Mi puoi dare del tu, ti prego. Please call me tu.
- Continuiamo a darci del Lei per ora. Let’s keep using Lei for now.
Five traps for English speakers
Trap 1: Lei = third singular, not second
The biggest mental shift: Lei takes parla, ha, viene, the same verb as he/she/it. Lei parli would be wrong (that’s the imperative form). For statements use Lei parla italiano, not Lei parli. The english you speak maps to italian third singular here.
Trap 2: pronouns are feminine even for men
La chiamo io works for any addressee, male or female. The la is the feminine direct-object pronoun matching the grammatical feminine of Lei, not the actual sex of the person. Same for le ho detto (I told you, indirect): le regardless of sex.
Trap 3: adjectives agree with the actual sex
Despite Lei being grammatically feminine, adjectives and past participles agree with the addressee’s real sex. Lei e contento (to a man), Lei e contenta (to a woman). Si e accomodato (male client), si e accomodata (female client). The pronouns stay feminine; the adjectives don’t.
Trap 4: imperative is congiuntivo presente, not imperativo
To give a polite order, italian uses the third singular form of the present subjunctive: parli, prenda, mi dica, si accomodi, non si preoccupi. The familiar imperative parla! prendi! belongs to tu. Pronouns go BEFORE the verb in formal: mi dica, si sieda, never dicami, siediti.
Trap 5: when in doubt, choose Lei
Italians forgive a non-native who uses Lei when tu would be fine: it sounds polite, slightly old-fashioned, never offensive. The reverse mistake (using tu when Lei is expected) can sound rude or disrespectful. Default to Lei with anyone over 25 you don’t know personally; let them invite you to switch.

Frequently asked questions
What is the italian formal Lei?
Italian formal Lei is the polite, third-singular feminine pronoun used to address one person you don’t know well, someone older, a customer or a professional. Verbs go in the third person singular (Lei parla, Lei ha). Object pronouns are la (direct), le (indirect), si (reflexive). Possessives are Suo, Sua, Suoi, Sue. Despite Lei being grammatically feminine, adjectives agree with the addressee’s actual sex.
When should I use Lei vs tu?
Default to Lei with strangers over 25, professionals (doctor, lawyer, official), customer-business contexts, older people you don’t know personally, and any formal email. Use tu with family, close friends, peers under 25-30 in casual settings, and people who have explicitly invited you to switch. When in doubt, Lei is always safer for non-natives.
Why is Lei feminine even when I’m talking to a man?
Historically italian Lei comes from Vostra Signoria (your lordship), a feminine noun phrase. The grammatical feminine has stuck even though Lei is used for both sexes. Verbs and pronouns follow the grammatical feminine: Lei parla, la chiamo, le ho mandato. But adjectives and past participles agree with the addressee’s actual sex: Lei e contento for a man, contenta for a woman.
How do I form the imperative for Lei?
Use the third person singular of the present subjunctive (congiuntivo presente). For -are verbs the ending is -i (parli, prenda becomes prenda… wait, that’s -ere): actually parlare u0026gt; parli, prendere u0026gt; prenda, dormire u0026gt; dorma, finire u0026gt; finisca. Pronouns go BEFORE the verb: mi dica (tell me), si accomodi (please sit), me lo dia (give it to me).
How do I switch from Lei to tu?
The traditional formula is Diamoci del tu! (Let’s call each other tu) or Possiamo darci del tu? (Can we use tu?). The proposal usually comes from the older or more senior person. Once accepted, both parties switch immediately. Going back to Lei after the shift would sound awkward and feel like distancing.
Should I capitalise Lei in writing?
In modern italian formal writing, Lei is often capitalised (Lei, La, Le, Suo, Sua) to distinguish it from third-person lei (she). The convention is more common in business correspondence and official letters. In casual or text-message register the capitalisation is dropped. Both styles are accepted; capital Lei signals extra formality.
What is the formal plural?
In modern italian voi serves as the formal plural, used for any group of people regardless of formality. The historical Loro (third-plural feminine, used for groups of formal addressees) survives in hyper-formal restaurant service and old-fashioned writing. In everyday italian, voi covers both informal and formal plural address.
What’s the most common imperative phrase with Lei?
Si accomodi (please sit / make yourself at home). Mi dica (tell me / how can I help). Non si preoccupi (don’t worry). Mi scusi (excuse me / I’m sorry). Prego, si serva (please help yourself). These five formulas cover most polite-customer interactions in shops, restaurants, hotels, offices.
