Negative Words as Subject (no 'non')
In Italian, if a negative word (like nessuno or niente) starts the sentence as the subject, the negative particle non is omitted. The negative word itself provides all the negation needed.
How It Works
In standard Italian negation, we typically see non before the verb. However, negative indefinite pronouns and adjectives follow a specific rule based on their position:
- Pre-verbal Subject: When nessuno (no one), niente (nothing), or nulla (nothing) is the subject and is placed before the verb, the word non must be omitted.
Example: Nessuno parla (No one is speaking). - Post-verbal Position: If these words follow the verb, you must use double negation with non.
Example: Non parla nessuno.
Morphology of Nessuno:
When used as an adjective before a noun, nessuno follows the same rules as the indefinite article 'uno' (truncation and elision):
- Nessun + masculine (e.g., nessun amico)
- Nessuno + masculine 's+consonant/z' (e.g., nessuno studente)
- Nessuna + feminine consonant (e.g., nessuna donna)
- Nessun' + feminine vowel (e.g., nessun'idea)
Note on Number: These words are always grammatically singular. Even if they imply a group of people, the verb must be in the 3rd person singular.
Examples (5)
- Nessuno sa la verità.
No one knows the truth.
Word by Word: No one knows the truth.
Since 'nessuno' is the subject and comes before the verb 'sa', we do not use 'non'.
- Niente è impossibile.
Nothing is impossible.
Word by Word: Nothing is impossible.
'Niente' is the subject at the start of the sentence, so the verb 'è' remains alone without 'non'.
- Nessun ragazzo ha mangiato la torta.
No boy ate the cake.
Word by Word: No boy has eaten the cake.
Here 'nessun' is an adjective modifying 'ragazzo'. As the subject phrase precedes the verb, 'non' is omitted.
- Nulla è cambiato qui.
Nothing has changed here.
Word by Word: Nothing is changed here.
'Nulla' is a more formal synonym for 'niente'. It follows the same rule when placed before the verb.
- Nessun'amica mi ha chiamato.
No (female) friend called me.
Word by Word: No friend me has called.
Note the elision (nessun') because 'amica' is feminine and starts with a vowel.
Common Mistakes
Using 'non' with a pre-verbal negative subject.
Nessuno non è venuto.Nessuno è venuto.In English, we say 'No one came.' In Italian, if 'nessuno' is first, adding 'non' is redundant and grammatically incorrect.
Using a plural verb with 'nessuno'.
Nessuno sono arrivati.Nessuno è arrivato.Negative indefinites like 'nessuno' are always singular, even if they refer to multiple people.
Incorrect truncation/elision of 'nessuno' as an adjective.
Nessun'amico è qui.Nessun amico è qui.Just like the article 'un', the masculine 'nessun' never takes an apostrophe. Only the feminine 'nessun'' does before a vowel.
