To use the verb 'to be' in simple present tense, you must match its three forms—'am,' 'is,' and 'are'—with the correct subject. Use 'am' with 'I,' 'is' with 'he,' 'she,' or 'it,' and 'are' with 'you,' 'we,' or 'they' to describe identity, states, and characteristics.
Welcome, English learners! If you want to build strong, clear sentences, understanding the verb 'to be' is the most important first step. It’s the most common verb in English and the foundation for describing the world around you. This guide will show you exactly how to use the verb 'to be' in simple present tense to talk confidently about yourself and other people.
What Are the Forms of 'To Be' in the Present Simple?
The verb 'to be' is an irregular verb, which means it doesn't follow the usual rules. In the simple present tense, it changes into three different forms depending on the subject (the person or thing doing the action).
This is called verb conjugation. Your main job is to memorize which form goes with which subject pronoun.
Here is the complete breakdown:
- I → am (*I am a student.*)
- You → are (*You are tall.*)
- He / She / It → is (*He is a doctor. She is happy. It is sunny.*)
- We → are (*We are friends.*)
- They → are (*They are from Brazil.*)
Notice that 'are' is used for the second person (you), and all plural forms (we, they).
How do I use the verb 'to be' in simple present tense for positive sentences?
Making a basic positive statement is simple. The structure is always the same: Subject + form of 'to be' + rest of the sentence.
Think of it as connecting a subject to a description. You are connecting a *who* or a *what* to information about them. This information can be a job, a feeling, a location, or a characteristic.
Examples about myself ('I')
- I am an English learner.
- I am excited.
- I am from London.
Examples about others ('You,' 'He,' 'She,' 'We,' 'They')
- You are my teacher.
- He is very smart.
- She is at the library.
- We are ready for the test.
- They are neighbors.
How Do I Make Negative Sentences with 'To Be'?
To make a sentence negative, you simply add the word 'not' after the verb 'to be'. The formula is: Subject + form of 'to be' + not + rest of the sentence.
To sound more natural, English speakers often use contractions, which are shortened forms.
- is not → isn't
- are not → aren't
Important: There is no common contraction for 'am not'. We always say, "I'm not."
Negative Examples
- I am not tired. (Contraction: I'm not tired.)
- You are not late. (Contraction: You aren't late.)
- She is not a scientist. (Contraction: She isn't a scientist.)
- We are not at home. (Contraction: We aren't at home.)
- They are not busy. (Contraction: They aren't busy.)
How do I ask questions with the verb 'to be' in simple present tense?
Asking a simple yes/no question is also straightforward. You just need to change the word order. Move the 'to be' verb to the beginning of the sentence, before the subject. The formula becomes: Form of 'to be' + Subject + rest of the sentence?
Question Examples
- Am I in the right class?
- Are you from Canada?
- Is he a good football player?
- Is it cold outside?
- Are we on time?
- Are they students?
To answer these questions, you use a short answer form: "Yes, I am." or "No, she isn't."

Frequently Asked Questions (FAQ)
When should I use 'is' versus 'are'?
Use 'is' for singular subjects in the third person. This includes the pronouns 'he,' 'she,' and 'it,' as well as any single person or object (e.g., 'The book is on the table,' 'My brother is a lawyer'). Use 'are' for the second-person subject 'you' and all plural subjects, like 'we,' 'they,' or multiple items (e.g., 'The books are on the table,' 'My parents are retired').
What is the contraction for 'I am not'?
While 'isn't' and 'aren't' are common, there is no standard contraction for 'am not' like 'amn't'. The correct and natural-sounding way to shorten 'I am not' is to contract the subject and verb: 'I'm not'. For example, "I'm not ready yet."
Can I just use 'be' in a simple present sentence?
No, you cannot use the base form 'be' directly with a subject in a simple present statement. You must always conjugate it into one of its three present forms: 'am,' 'is,' or 'are'. For example, you cannot say "I be happy." The correct sentence is "I am happy."
How do I use 'to be' to talk about my job?
The verb 'to be' is perfect for stating your profession. You use the structure: I + am + a/an + [Job Title]. For example: "I am an engineer," "I am a teacher," or "I am a student."
Why is the verb 'to be' so irregular and important?
The verb 'to be' is irregular because it has ancient origins and has been used so frequently throughout the history of the English language that its unique forms have survived. It's crucial because it's a linking verb (connecting a subject to a description) and an auxiliary verb (helping form other tenses, like the present continuous: 'He is running'). Mastering it is essential for almost every type of English sentence.
