Learn Present Be Verb (am/is/are) in English
Use am, is, and are to describe people, places, and things.
Grammar Focus
The be verb (am, is, are) is the most fundamental verb in English. It connects a subject to information about identity, description, location, or state. Unlike action verbs, the be verb does not describe what someone does — it describes what someone or something is.
- Use am with the subject "I": "I am a student."
- Use is with singular subjects (he, she, it, or a singular noun): "She is happy."
- Use are with plural subjects and "you": "They are teachers."
- The be verb is used to give names, nationalities, ages, jobs, locations, and descriptions: "He is 25 years old."
- In spoken English, contractions are very common: "I'm," "you're," "he's," "she's," "it's," "we're," "they're."

Questions
Common Mistakes
Using 'is' instead of 'are' with plural subjects
Tip: When the subject is plural (they, we, you, or multiple nouns), always use 'are', not 'is'.
Omitting the be verb entirely
Tip: In English, you cannot skip the be verb. Every sentence needs a verb, and 'is/am/are' counts as the main verb here.
Using the wrong form with 'you'
Tip: 'You' always takes 'are', even when referring to just one person. Never use 'is' or 'am' with 'you'.

One of the first things you learn when studying English is the verb 'to be'. The present forms of this verb — am, is, and are — appear in almost every conversation you will ever have in English. Whether you are introducing yourself, describing a friend, talking about where something is, or expressing how you feel, you will need the present be verb. It is not an exaggeration to say that without mastering am, is, and are, it is nearly impossible to communicate basic information in English. The be verb is special because it works differently from most English verbs. Verbs like 'run', 'eat', or 'work' describe actions — things people do. But the be verb describes states of being. It connects a subject to information about who or what that subject is, what it looks like, where it is, or how it feels. This is why grammar teachers often call it a 'linking verb' or a 'copula'. For beginner English learners, the present be verb is usually one of the first grammar topics covered, and for good reason. Once you understand how to use am, is, and are correctly, you can start building real sentences right away. You can tell someone your name, your job, your nationality, and your age. You can describe people and places. You can ask and answer basic questions. This lesson is designed for absolute beginners and for intermediate learners who want to review and solidify their understanding of the be verb. You will learn the rules for choosing between am, is, and are, how to make negative sentences, how to ask questions, and how to avoid the most common mistakes English learners make with this verb. By the end, you will have a strong foundation that supports everything else you learn in English grammar.
What is the Present Be Verb in English?
The present be verb refers to the three present-tense forms of the verb 'to be': am, is, and are. These forms are used to describe the current state, identity, location, or characteristics of people, places, and things. Unlike action verbs, the be verb does not tell us what someone does — it tells us what they are or what they are like right now. For example, when you say 'She is a doctor', you are not describing an action she performs. You are describing her identity. When you say 'The book is on the desk', you are describing where the book exists at this moment. The be verb acts as a bridge between the subject of your sentence and the information you want to share about it. Every language has some way to express this kind of meaning, but English always requires an explicit verb. You cannot simply place an adjective or noun after a subject without connecting them with am, is, or are. This is one of the most important things for new English learners to understand early on. The be verb is the foundation of English sentence structure, and every learner benefits from mastering it as completely as possible.

When to Use Am, Is, and Are
The choice between am, is, and are depends entirely on the subject of your sentence. There are three clear rules that govern this choice, and once you memorize them, selecting the right form becomes automatic. Use 'am' only with the first-person singular subject 'I'. This is the most limited of the three forms, but it is used constantly in everyday speech. Any time you talk about yourself in the present tense with the be verb, 'am' is the only correct option. Use 'is' with all third-person singular subjects. This includes the pronouns he, she, and it, as well as any singular noun. So 'the dog is friendly', 'my teacher is helpful', and 'it is cold today' all use 'is' because the subject is singular and not 'I' or 'you'. Use 'are' with you, we, they, and all plural nouns. This is important to remember: even when 'you' refers to just one person, English still uses 'are'. 'Are' is also used with any noun that refers to more than one thing, such as 'the children are happy' or 'my parents are at home'. Practicing these three rules consistently will make them feel natural very quickly.
Form and Structure of the Be Verb
Understanding the structure of sentences with am, is, and are helps you build correct sentences in three different forms: affirmative, negative, and question. For affirmative sentences, the structure is straightforward: subject, then am/is/are, then the complement. The complement is the word or phrase that follows the be verb and gives information about the subject. For example: 'I am happy', 'She is a nurse', 'We are from Spain'. In spoken English, contractions are standard: 'I'm happy', 'She's a nurse', 'We're from Spain'. For negative sentences, you add 'not' after the be verb: 'I am not ready', 'He is not here', 'They are not students'. Contractions for the negative are also very common: 'I'm not ready', 'He isn't here' or 'He's not here', 'They aren't students' or 'They're not students'. Note that 'amn't' does not exist in standard English — 'I'm not' is the only contraction for 'I am not'. For yes/no questions, you invert the subject and the be verb: 'Am I late?', 'Is she your sister?', 'Are they coming?' To answer, use the short form: 'Yes, she is' or 'No, she isn't'. For information questions, a question word comes first: 'Where is he?', 'Who are they?', 'What is your name?' Practicing all three forms together will build strong all-around fluency with the be verb.
Common Mistakes with Am, Is, and Are
Even after learning the basic rules, English learners often make certain predictable mistakes with the present be verb. Being aware of these mistakes can help you avoid them. The first and most common mistake is using 'is' with plural subjects. Many learners say 'They is happy' or 'My friends is here' because 'is' feels like the default form. But plural subjects always require 'are'. Remember: if you can replace the subject with 'they', use 'are'. The second very common mistake is dropping the be verb entirely. In many languages, it is perfectly correct to say the equivalent of 'She very smart' or 'I tired'. But in English, you cannot skip the verb. You must always include am, is, or are. Sentences without a verb are incomplete in English. The third frequent error involves the word 'you'. Because 'you' can refer to one person or several people, learners sometimes assume that when talking to just one person, they should say 'You is my friend'. This is always wrong. 'You' takes 'are' in every situation, singular or plural. The sentence is always 'You are my friend'. Being aware of these three errors and actively monitoring for them in your speaking and writing practice will help you eliminate them quickly.
Why Mastering the Be Verb Matters
The present be verb is not just a beginner topic that you learn and then leave behind. It is a foundational structure that appears throughout your entire English learning journey. Many advanced grammar structures in English are built on the be verb: the present continuous tense uses 'am/is/are + verb-ing', the passive voice uses 'am/is/are + past participle', and many adjective phrases and noun phrases rely on the be verb to connect ideas. In real life, you will hear and use the be verb in every single conversation. When you meet someone new, when you ask for directions, when you describe how you feel, when you talk about your family — am, is, and are are always there. Native speakers also use contractions constantly, so training your ear to hear 'she's', 'they're', and 'it's' as forms of the be verb will dramatically improve your listening comprehension. Mastering this verb early gives you confidence and makes every other English lesson easier to understand. It is the single most important verb in the English language, and the time you invest in understanding it deeply will pay dividends at every stage of your learning.

Frequently Asked Questions
- What is the difference between am, is, and are?
- Am, is, and are are the three present-tense forms of the verb 'to be'. You use 'am' with 'I', 'is' with he, she, it, and singular nouns, and 'are' with you, we, they, and plural nouns. The choice depends entirely on the subject of your sentence.
- Why do we say 'you are' even for one person?
- In modern English, 'you' always takes 'are', whether you are speaking to one person or many. Historically, English had a singular form 'thou' and a plural form 'you', but 'thou' is no longer used in everyday speech. Today 'you' serves both purposes, but the verb form remains 'are' in all cases.
- Can I use contractions like I'm and she's in formal writing?
- Contractions are standard and natural in spoken English and informal writing, such as emails to friends or text messages. In formal writing — like academic essays, business reports, or official letters — it is generally better to write the full forms: 'I am', 'she is', 'they are'. However, many modern style guides accept contractions even in semi-formal contexts.
- How do I make a negative sentence with am, is, and are?
- To make a negative sentence, add 'not' after the be verb: 'I am not ready', 'She is not here', 'They are not students'. In spoken English, contractions are used: 'I'm not ready', 'She isn't here', 'They aren't students'. Note that there is no standard contraction for 'am not' — the form 'amn't' is not used in standard English.
- What kind of information can I give with the be verb?
- The present be verb is used to express many types of information about a subject: identity (I am a teacher), nationality (She is French), age (He is 30), physical description (They are tall), emotional state (I am nervous), location (We are at the park), and time or weather (It is cold today). It is an incredibly versatile verb used in almost every topic of conversation.
- Is the be verb used in any other English tenses?
- Yes, the verb 'to be' is essential in many English tenses and structures beyond the simple present. It forms the present continuous tense (I am studying), the past continuous (she was running), the passive voice (the letter was written), and more. Learning the present forms am, is, and are is the first step toward understanding all of these advanced structures.
