The simplest ways to use the verb 'to be' are for stating who or what something is (identity), describing its qualities, and saying where it is (location). In the present tense, its three forms—am, is, and are—act as a bridge, connecting a subject to crucial information about it.
Mastering the verb 'to be' is one of the first and most important steps in learning English. It’s the most common verb in the language, and you’ll find it everywhere! While it might seem tricky with its different forms, it’s actually quite straightforward once you understand the basic rules. In this guide, we’ll explore the simplest ways to use the verb 'to be' to help you build clear, correct sentences and boost your confidence.
What are the three basic forms of 'to be' in the present tense?
Before you can build sentences, you need to know which form of the verb to use. In the present tense, 'to be' changes into three different words depending on the subject of the sentence. This is called conjugation. Getting this subject-verb agreement right is fundamental to basic English grammar.
- Am is used only with the subject I. (I am)
- Is is used with singular subjects like he, she, it, or a single noun (e.g., *the dog, my sister, the book*).
- Are is used with the subject you, and with plural subjects like we, they, or plural nouns (e.g., *the dogs, my sisters, the books*).
Using 'Am'
This form is your personal tag. It only ever follows the pronoun 'I'.
- I am happy.
- I am a student.
- I am from Spain.
Using 'Is'
Use 'is' when you are talking about one other person, place, or thing.
- He is a doctor.
- She is my friend.
- It is a beautiful day.
Using 'Are'
'Are' is the most versatile form. You use it when speaking to someone ('you'), about a group you are in ('we'), or about any other group of people or things ('they').
- You are very smart.
- We are in the classroom.
- They are new shoes.

Frequently Asked Questions (FAQ)
Q1: What is the difference between 'is' and 'are'?
'Is' is used with singular subjects (one person or thing), such as 'he', 'she', 'it', or 'the dog'. 'Are' is used with plural subjects (more than one person or thing), like 'we', 'they', or 'the dogs'. 'Are' is also always used with 'you', even when you are talking to just one person.
Q2: How do you use the verb 'to be' in the past tense?
In the past tense, 'to be' changes to 'was' and 'were'. You use 'was' for singular subjects (I, he, she, it), and 'were' for plural subjects (we, they) and 'you'. For example: "I was tired yesterday," and "They were at the park."
Q3: Can I use 'be' by itself in a simple sentence?
In a simple present tense or past tense sentence, you cannot use the word 'be' by itself. You must use its conjugated form ('am', 'is', 'are', 'was', 'were'). The word 'be' is the infinitive form, used after other verbs like 'will' (I will be there) or 'to' (I want to be a pilot).
Q4: Is 'be' the most important verb in English?
Yes, it's arguably the most important and definitely the most common. It functions as a main verb (as shown in this article) and also as an auxiliary or 'helping' verb to form other tenses, like the present continuous (e.g., "She is running").
Q5: Why do we say 'you are' for just one person?
Grammatically, modern English treats 'you' as a plural pronoun in all situations. Historically, English had a singular form ('thou'), but it fell out of common use centuries ago. Now, we use 'you are' whether we are speaking to one person or a large group.
