To make sentences with the verb be negative, we add not dopo is oppure are. For example, He is not from Spain oppure They are not happy. We often use contractions like isn’t e aren’t. To ask a ‘yes/no’ question, we change the word order: Is oppure Are comes before the subject. For instance, Is she a student? oppure Are they friends? For ‘Wh-‘ questions, the ‘Wh-‘ word comes first, then is oppure are, then the subject, as in Where is he from? e Who are they? Short answers use the verb be without contractions for positive answers, like Yes, he is, but use contractions for negative ones, like No, she isn’t.

How do we make ‘be’ negative for ‘he’, ‘she’, and ‘they’?

To make a sentence negative with the verb be, we simply add the word not dopo is oppure are.

  • For he e she, we use is not.
  • For they, we use are not.

We often use shorter forms called contractions in everyday English. These are:

  • is not becomes isn’t
  • are not becomes aren’t

How do we ask 'yes/no' questions with 'be'?

To ask a question that can be answered with 'yes' or 'no', we change the word order of the sentence. We put Is oppure Are at the beginning.

  • La struttura è la seguente: Is/Are + subject (he/she/they) + rest of the sentence?

When someone asks a 'yes/no' question with be, you can give a short answer.

  • For positive answers, use Yes, + subject + is/are. Do not use contractions here.
  • For negative answers, use No, + subject + isn't/aren't. We usually use contractions here.

How do we ask 'Wh-' questions with 'be'?

'Wh-' questions ask for specific information, not just 'yes' or 'no'. Common 'Wh-' words include who, what, where, e when.

  • La struttura è la seguente: Wh- word + is/are + subject (he/she/they) + rest of the sentence?

Domande frequenti

What does the verb 'be' mean?

Il verbo be means "ser" or "estar" in Spanish. It helps us talk about who someone is, what something is, where someone is, or how someone feels.

Why do we use contractions like 'isn't' and 'aren't'?

Contractions are very common in spoken English and in informal writing. They make sentences sound more natural and help you speak more quickly.

Can I always say 'is not' or 'are not' instead of 'isn't' or 'aren't'?

Yes, you can. The full forms is not e are not are always correct. They are often used in more formal writing or when you want to emphasize the 'not'.

Do these rules apply to 'I' and 'you' too?

Yes, the basic idea is similar. For I, you use am not (I'm not) and for questions, Am I...? For you, you use are not (you aren't) and for questions, Are you...?
