After a preposition, when the third person acts on itself, Italian uses a dedicated reflexive tonic pronoun: sé, written with an accent. Pensa a sé means "he thinks about himself" — not about someone else. Parla solo di sé means "she only talks about herself." The same pronoun covers all third persons (he, she, it, they) and all genders, because it is reflexive: the referent is whoever the subject happens to be.
This page covers the form, the accent rule that makes it different from the conjunction se (if), the everyday idioms built on it (da sé, fuori di sé, in sé), and the emphatic compound se stesso / sé stesso. It also draws the all-important contrast with non-reflexive lui / lei: confusing them is the single most common B1 error in this area.
The form: sé (with accent)
The reflexive tonic pronoun is sé, with a written accent. It is invariable — there is no separate masculine, feminine, singular, or plural form. The same word covers:
| Subject | Reflexive tonic | Translation |
|---|---|---|
| lui | sé | himself |
| lei | sé | herself |
| esso / essa (it) | sé | itself |
| loro (m. / f.) | sé | themselves |
| Lei (formal) | sé | yourself (formal) |
The accent is mandatory. Without it, you would have written the conjunction se (if, whether), which is a different word entirely.
Pensa solo a sé e ai suoi interessi.
He only thinks about himself and his own interests.
Si è chiusa in sé dopo la notizia.
She withdrew into herself after the news.
Parlano sempre di sé, mai degli altri.
They always talk about themselves, never about others.
Tornò in sé dopo qualche minuto.
He came to (regained consciousness) after a few minutes. (idiom: tornare in sé)
Ognuno deve pensare a sé.
Everyone has to look out for themselves. (impersonal, but still 3rd-person reflexive)
The reflexive condition is structural: sé is required only when the subject and the prepositional object are the same entity. If they're different, you use the regular tonic pronouns lui, lei, loro — see the contrast section below.
The accent rule: sé vs se
Italian distinguishes two words that would otherwise be spelled identically:
| Word | Accent | Meaning | Example |
|---|---|---|---|
| sé | yes — acute, written é | himself / herself / themselves | pensa a sé |
| se | none | if, whether | se piove, resto a casa |
This is one of a small handful of accent-pairs in Italian where the accent carries meaning (others include e / è, si / sì, li / lì, la / là). Forgetting the accent on sé is treated as a real spelling error in formal writing, not just a typographic detail.
Se vuoi parlare di sé, fallo con calma.
If you want to talk about yourself, do it calmly. (se = if; sé = oneself)
Si chiede sempre se gli altri pensano a sé come lui pensa a sé.
He always wonders whether others think about themselves the way he thinks about himself.
With prepositions: a sé, di sé, per sé, in sé, con sé
Sé combines with the same prepositions as any other tonic pronoun. The list below covers the most common collocations.
| Preposition + sé | Meaning |
|---|---|
| a sé | to/for himself |
| di sé | about / of himself |
| per sé | for himself |
| in sé | in himself / in itself |
| con sé | with him/her (with one's person) |
| su di sé | on himself / about himself |
| da sé | by himself / on its own |
Lavora per sé, non per un'azienda.
He works for himself, not for a company.
Aveva con sé solo uno zaino e un libro.
She had only a backpack and a book with her.
L'idea, in sé, non è sbagliata.
The idea, in itself, isn't wrong. (in sé = in itself)
Ha tirato fuori il meglio di sé in quella partita.
He brought out the best of himself in that match.
Notice that con sé does not use the di-insertion that some other prepositions require with personal pronouns (see Con me, di me). Con is one of the core prepositions and combines directly with sé, just as it does with me and te.
The idiom da sé: "by oneself, on its own"
Da sé is one of the most useful Italian idioms. It means by oneself, of one's own accord, automatically, on its own — the action happens without external help.
La porta si chiude da sé, non spingere.
The door closes on its own, don't push it.
È riuscito a risolvere il problema da sé.
He managed to solve the problem on his own.
Va da sé che dobbiamo arrivare in orario.
It goes without saying that we have to arrive on time. (very common idiom)
Si capisce da sé che è una battuta.
It's self-evident that it's a joke.
The idiom va da sé — literally "it goes by itself" — is the everyday Italian for "it goes without saying" or "obviously." It opens hundreds of thousands of sentences in newspapers, essays, and conversations.
Da sé vs da solo
Closely related but not identical, the expression da solo / da sola / da soli / da sole also means "alone, by oneself." The difference matters:
| Expression | Restriction | Register | Typical use |
|---|---|---|---|
| da sé | 3rd person only | slightly elevated | spontaneous action, fixed idioms |
| da solo / -a / -i / -e | any person, agrees in gender/number | everyday spoken Italian | doing something alone |
Lo faccio da solo, non ho bisogno di aiuto.
I'll do it myself, I don't need help. (1st person — must use 'da solo')
Vivo da sola da tre anni.
I've been living alone for three years. (1st person fem.)
Marco preferisce studiare da solo.
Marco prefers to study alone.
Marco preferisce risolvere i problemi da sé.
Marco prefers to solve problems on his own. (3rd person, slightly more formal)
In ordinary speech, da solo is far more common than da sé, and many learners initially never need the latter. Da sé concentrates in two contexts: the idiom va da sé, and slightly elevated prose ("the system regulates itself" — il sistema si regola da sé).
Emphatic se stesso / sé stesso
For strong reflexive emphasis — "himself, in person" — Italian combines the tonic pronoun with stesso, which agrees in gender and number with the subject.
| Person | Form | Translation |
|---|---|---|
| 1sg | me stesso / me stessa | myself (emph.) |
| 2sg | te stesso / te stessa | yourself (emph.) |
| 3sg m. | se stesso / sé stesso | himself (emph.) |
| 3sg f. | se stessa / sé stessa | herself (emph.) |
| 1pl m. | noi stessi | ourselves (emph., m.) |
| 1pl f. | noi stesse | ourselves (emph., f.) |
| 2pl m. | voi stessi | yourselves (emph., m.) |
| 2pl f. | voi stesse | yourselves (emph., f.) |
| 3pl m. | se stessi / sé stessi (loro stessi for non-reflexive emphasis) | themselves (emph., m.) |
| 3pl f. | se stesse / sé stesse | themselves (emph., f.) |
The form stesso agrees with the subject of the sentence; the se / sé element stays invariable. Use this construction when you want to underline that the action loops back specifically onto the doer and not onto someone else.
Devi credere in te stesso.
You have to believe in yourself.
Pensa solo a se stesso.
He only thinks about himself. (emphatic — stronger than 'pensa a sé')
Non mentire a te stesso.
Don't lie to yourself.
Hanno fiducia in se stessi.
They have confidence in themselves.
Lavoriamo per noi stessi, non per gli altri.
We're working for ourselves, not for others.
The accent question: se stesso or sé stesso?
A real orthographic question splits modern usage. Traditional Italian wrote se stesso without an accent, on the grounds that the conjunction se (if) cannot grammatically appear in this position — there's no ambiguity to resolve. The Accademia della Crusca and major dictionaries accepted this for most of the 20th century.
In 2016, however, the Treccani (Italy's authoritative cultural institution) officially recommended sé stesso with the accent, on the grounds of consistency with the standalone form sé and to avoid forcing readers to remember a special exception.
Modern Italian therefore allows both spellings as correct:
- se stesso — traditional, still accepted by major dictionaries
- sé stesso — Treccani-recommended, increasingly common in print since 2016
In your own writing, pick one and stick with it. In reading, you will encounter both. The pronunciation is identical.
Il pittore è specchio di se stesso. (or: di sé stesso)
The painter is a mirror of himself. (both spellings accepted)
Sé vs lui / lei: the reflexive contrast
This is the crucial distinction. Sé is reserved for reflexive prepositional uses — when the prepositional object refers back to the subject. If the prepositional object is someone else, you use the ordinary tonic pronouns lui, lei, loro.
| Sentence | Pronoun | Reading |
|---|---|---|
| Marco pensa a sé. | sé | Marco thinks about himself. |
| Marco pensa a lui. | lui | Marco thinks about him (someone else). |
| Lucia parla di sé. | sé | Lucia talks about herself. |
| Lucia parla di lei. | lei | Lucia talks about her (someone else). |
| Lo fa per sé. | sé | He does it for himself. |
| Lo fa per lui. | lui | He does it for him (someone else). |
This contrast is not optional. Choosing the wrong pronoun changes the meaning of the sentence.
Anna parla sempre di sé.
Anna always talks about herself.
Anna parla sempre di lei.
Anna always talks about her (some other woman). (different meaning!)
Marco lavora per sé.
Marco works for himself (i.e. is self-employed).
Marco lavora per lui.
Marco works for him (someone else, e.g. a boss).
English does not face this ambiguity because himself and him are obviously different words. Italian sé and lui are similarly distinct — but only if you know to use sé in the reflexive position. Many B1 learners default to lui / lei everywhere and produce sentences that mean something they did not intend.
Sé in proverbs and fixed expressions
A handful of fixed expressions with sé are deeply embedded in Italian. Recognise them in reading; use them sparingly in your own writing until they feel natural.
Chi fa da sé fa per tre.
If you want something done right, do it yourself. (proverb — literally: who does by himself does for three)
Va da sé che bisogna prenotare in anticipo.
It goes without saying that you have to book in advance.
L'opera, di per sé, è un capolavoro.
The work, in and of itself, is a masterpiece. (di per sé = in itself)
Tornare in sé dopo lo svenimento richiede tempo.
Coming to after fainting takes time.
The expressions va da sé, di per sé, and in sé belong to careful written and spoken Italian. They tend to mark a slightly more elevated register than everyday speech, but they are by no means literary-only.
Common mistakes
❌ Pensa solo a se.
Incorrect — the reflexive tonic must carry the accent: sé.
✅ Pensa solo a sé.
Correct — sé with acute accent.
❌ Marco pensa a lui (intending: about himself).
Wrong meaning — without the reflexive sé, this means Marco thinks about someone else.
✅ Marco pensa a sé.
Correct — sé signals that the prepositional object is Marco himself.
❌ Faccio tutto da sé.
Incorrect — 'da sé' is restricted to 3rd person; 1st-person 'I' uses 'da solo / da sola'.
✅ Faccio tutto da solo.
Correct — da solo for any person, da sé for 3rd person only.
❌ Devi avere fiducia in sé stesso (addressed to a 'tu' subject).
Incorrect — when the subject is 'tu', the emphatic form is 'te stesso', not 'sé stesso'.
✅ Devi avere fiducia in te stesso.
Correct — the emphatic form agrees with the subject: te stesso for tu.
❌ Sé vuoi parlare di te, parla pure.
Incorrect — 'sé' here is the conjunction 'if', which has no accent.
✅ Se vuoi parlare di te, parla pure.
Correct — se (if) without accent, te (you) without accent.
❌ Era fuori di lui dalla rabbia.
Incorrect — 'fuori di sé' is a fixed reflexive idiom; 'fuori di lui' would mean 'outside of him' physically.
✅ Era fuori di sé dalla rabbia.
Correct — fuori di sé = beside oneself with emotion.
Key takeaways
Sé is the third-person reflexive tonic pronoun, used after prepositions when the object refers back to the subject: pensa a sé, parla di sé, lo fa per sé. It is invariable for gender and number.
The accent is mandatory to distinguish sé (oneself) from se (if). Use the acute: sé.
Da sé is the everyday idiom for "by oneself / on its own / automatically": va da sé (it goes without saying), si chiude da sé (it closes by itself). It is restricted to the third person.
Da solo / da sola / da soli / da sole is the everyday equivalent for any person, agreeing in gender and number with the subject. Use da solo when speaking about yourself.
Se stesso / sé stesso is the emphatic compound form. Both spellings are accepted in modern Italian (Treccani 2016 endorses sé stesso with accent). The stesso part agrees with the subject in gender and number.
Sé vs lui / lei is meaningful, not stylistic. Marco pensa a sé (Marco thinks about himself) ≠ Marco pensa a lui (Marco thinks about someone else). Choose by checking whether the prepositional object refers back to the subject.
