How do we use “be” in positive sentences?
The verb be changes its form depending on the subject (the person or thing doing the action).
- Para I, we use am.
- Para he, she, it (singular subjects), we use is.
- Para you, we, they (plural subjects), we use are.
We often use contractions (shorter forms) in spoken English and informal writing. For example, I am becomes I’m.
How do we make “be” negative?
To make a sentence with the verb be negative, we simply add the word not after am, is, o are.
- I am not
- He is not
- They are not
We also have negative contractions. For example, is not becomes isn’t. For I am not, the contraction is usually I’m not.
When do we use contractions with “be”?
Contractions are very common in everyday English. You will hear them all the time when people speak.
- Speaking: Always use contractions when you speak. It sounds more natural.
- Informal Writing: Use contractions in emails to friends, text messages, or informal notes.
- Formal Writing: In formal writing, like academic essays or official reports, it is better to use the full forms (I am, she is not).
| Subject | Positive Form | Negative Form | Positive Contraction | Negative Contraction |

Spanish speakers sometimes forget to use the verb be. In Spanish, you might say ‘Yo feliz’ but in English, you must say I am happy. Always remember to include am, is, o are.
Another common mistake is confusing ser y estar. In English, be covers both. For example, I am a student (ser) and I am in the classroom (estar) both use am.
Also, make sure the verb matches the subject. It is She is, not She are. Always check the subject to choose the correct form of be.
