Adjectives with Impersonal 'si'

Level 3

In Italian, when you make a general statement using the impersonal si and a copular verb (like 'to be'), the adjective describing the state is always plural (usually masculine plural '-i').

How It Works

This pattern is used to express general truths, proverbs, or shared experiences. It is a specific rule for the impersonal si when followed by a predicate adjective.

1. Verb Agreement: The verb always remains in the 3rd person singular (e.g., si è, si diventa, si sembra).

2. Adjective Agreement: Unlike standard sentences where the adjective matches the verb's number, here the adjective becomes plural. This is because the 'si' logically represents a group of people ('we', 'one', or 'people').

  • Masculine Plural (-i): The default for general statements (e.g., Quando si è stanchi...).
  • Feminine Plural (-e): Used only if the context refers exclusively to women (e.g., Quando si è incinte...).

3. Reflexive Verbs: If the verb is reflexive, the sequence si si is not allowed. It changes to ci si (e.g., Ci si sente stanchi).

4. Compound Tenses: The auxiliary is always essere. The past participle also follows the plural rule if the verb normally takes essere (e.g., Si è stati felici).

Examples (5)

  1. Quando si è contenti, il tempo passa velocemente.

    When one is happy, time passes quickly.

    Word by Word: When one is happy (plural), the time passes quickly.

    Notice that 'si è' is singular, but 'contenti' is masculine plural.

  2. Se si è amici, ci si aiuta sempre.

    If people are friends, they always help each other.

    Word by Word: If one is friends (plural), one helps each other always.

    Here 'amici' is plural because it refers to a general relationship between people.

  3. Non si è mai troppo vecchi per imparare.

    One is never too old to learn.

    Word by Word: Not one is never too old (plural) for to learn.

    A classic proverb structure using the masculine plural 'vecchi'.

  4. In vacanza si è più rilassati.

    On vacation, people are more relaxed.

    Word by Word: In vacation one is more relaxed (plural).

    The adjective 'rilassati' describes the general state of people on holiday.

  5. Quando si è stanche, bisogna riposare.

    When one is tired (referring to women), it is necessary to rest.

    Word by Word: When one is tired (feminine plural), it needs to rest.

    The feminine plural 'stanche' is used here because the context implies a group of females.

Common Mistakes

  • Using a singular adjective to match the singular verb.

    Quando si è stanco...
    Quando si è stanchi...

    Even though 'si è' is singular, the adjective must be plural because it refers to people in general.

  • Using a plural verb to match the plural adjective.

    Quando si sono stanchi...
    Quando si è stanchi...

    The impersonal 'si' always requires the 3rd person singular form of the verb.

  • Using 'avere' as an auxiliary in compound tenses.

    Si ha stati felici.
    Si è stati felici.

    Impersonal constructions with adjectives always use 'essere' as the auxiliary verb.

Learn This First

To understand why adjectives are plural in impersonal 'si' constructions (e.g., 'si è contenti'), you first need to know how the impersonal 'si' works with singular verbs. You also need a firm grasp of the verb 'essere' and the standard rules of adjective agreement to appreciate how this specific rule deviates from the expected singular agreement.
