The impersonal si is Italian's elegant way of making general statements without specifying who is doing the action — equivalent to English "one," "you," "people," "we," or passive constructions like "it is said." In Italia si mangia bene (In Italy people eat well), Come si dice in italiano? (How do you say in Italian?), Non si fa così (That's not how it's done), Si dice che... (It is said that...). The structure is simply si + verb in the third person, and it's the construction you'll see on signs, in recipes, in instructions, and throughout everyday speech.
The one rule that catches every learner is verb agreement with transitive verbs. When the impersonal si has a direct object, the verb agrees in number with that object — not with si itself. Si vende una casa (singular object → singular verb), Si vendono due case (plural object → plural verb). With intransitive verbs, the verb stays singular: Si dorme bene qui. Another quirk: adjectives and past participles after impersonal si are always in the masculine plural, regardless of who's actually being talked about — Quando si è stanchi, si dorme. Reflexive verbs used impersonally take ci si to avoid the impossible si si — Ci si alza presto in campagna (One gets up early in the countryside). The exercises below will guide you through all of these patterns until impersonal constructions feel as natural as the personal ones.
The impersonal 'si' is used in Italian to make general statements — equivalent to English 'one', 'you', 'people', 'we', or passive constructions like 'it is said'. It removes any specific subject from the sentence, expressing something that people in general do, say, or experience. The construction uses 'si' placed before a verb conjugated in the third person.
| Verb type | Italian | English |
|---|---|---|
| Intransitive (no object) | Si viaggia molto. | People travel a lot. |
| Intransitive (no object) | Si dorme bene qui. | One sleeps well here. |
| Transitive + singular object | Si vende una casa. | A house is being sold. |
| Transitive + plural object | Si vendono delle case. | Houses are being sold. |
| General custom | Si mangia bene in Italia. | People eat well in Italy. |
| Negative | Non si fa così! | That's not how it's done! |
When the impersonal 'si' is used with a transitive verb (a verb that takes a direct object), the verb agrees in number with the object — not with 'si' itself. If the object is singular, use the 3rd person singular. If the object is plural, use the 3rd person plural. Examples: 'Si vende un appartamento.' (singular object → singular verb) vs 'Si vendono due appartamenti.' (plural object → plural verb). With intransitive verbs or when there is no article-defined object, always use the singular: 'Si parla italiano.' but 'Si parlano molte lingue.'
| Italian sentence | Verb form | Reason |
|---|---|---|
| Si vende una casa. | vende (singular) | Object 'una casa' is singular |
| Si vendono due case. | vendono (plural) | Object 'due case' is plural |
| Si parla italiano. | parla (singular) | Language = uncountable / intransitive feel |
| Si parlano molte lingue. | parlano (plural) | Object 'molte lingue' is plural |
| Si mangia la pizza. | mangia (singular) | Object 'la pizza' is singular |
| Si mangiano le pizze. | mangiano (plural) | Object 'le pizze' is plural |
When an adjective or past participle follows the impersonal 'si' (especially with the verb 'essere'), it must be in the MASCULINE PLURAL form — regardless of the gender of the actual people involved. This is a fixed grammatical convention. Examples: 'Quando si è stanchi, si dorme.' (When one is tired, one sleeps.) — stanchi is masculine plural. 'Se si è contenti, si lavora meglio.' (If one is happy, one works better.) — contenti is masculine plural. 'Da giovani, si è spensierati.' (When young, one is carefree.) — spensierati is masculine plural.
Both impersonal 'si' and reflexive 'si' look identical, but they have different meanings. Reflexive 'si' means the subject acts on itself (e.g., 'Mario si lava' = Mario washes himself). Impersonal 'si' expresses a general action with no specific subject (e.g., 'In Italia, si mangia bene' = In Italy, people eat well). When a reflexive verb must be used impersonally, Italian uses 'ci si' to avoid the impossible 'si si': 'Ci si lava le mani prima di mangiare.' (One washes one's hands before eating.) 'Ci si alza presto in campagna.' (One gets up early in the countryside.)
1. Intransitive verbs: always si + 3rd person SINGULAR. 2. Transitive verbs: verb agrees with the object (singular object = singular verb; plural object = plural verb). 3. Adjectives after impersonal si are always MASCULINE PLURAL — even if all real speakers are female. 4. For reflexive verbs used impersonally, use 'ci si' (not 'si si'). 5. The impersonal si is very common in signs, instructions, recipes, and general statements about customs and habits.

Pasqualino Ferrari (Super Squalo) teaches you 1-on-1 via video call. No commitment, no package.
The impersonal "si" expresses general statements without a specific subject — equivalent to English "one", "you", "people", or "they": "Si mangia bene in Italia" (People eat well in Italy), "Si dice che..." (It is said that...). The verb stays in the third person singular when there is no specific object.
With intransitive verbs the verb is always third-person singular: "Si dorme bene" (One sleeps well). With transitive verbs the verb agrees with the object: "Si vende una casa" (singular) vs "Si vendono case" (plural). This dual behaviour confuses learners but follows a clear rule — match the noun.
When an adjective follows "si è/si sta", it must be masculine plural by convention, even when referring to women or mixed groups: "Quando si è stanchi, si dorme" (When one is tired, one sleeps). The implicit subject of si is grammatically treated as masculine plural — a fixed rule you simply memorize.
You see it everywhere in Italy: "Si prega di non fumare" (Please do not smoke), "Qui si parla inglese" (English spoken here), "Affittasi" (For rent — note the suffixed si). It creates a neutral, official tone perfect for public notices, recipes, and instructions.
