Has vs. have! One of the most common mistakes ESL learners make is confusing has and have. They come from the same verb (have), but we use them with different subjects in English. In this lesson, you’ll learn the core rule, see clear examples, and avoid common mistakes.
Has vs. Have
What are the differences between these two verbs?
Subject–Verb Agreement (Core Rule)
The most important rule is subject–verb agreement. Has is used with the third-person singular (he, she, it). Have is used with I, you, we, they and plural nouns.
- He has a car.
- She has a cat.
- It has a scratch.
- I have a car.
- You have a car.
- We have a car.
- They have a car.
- My friends have a car.
Conjugation and Contractions
“Have” is the base form of the verb. “Has” is the third-person singular present form. “Had” is the past tense of both has and have.
- I have a bike. → I’ve a bike. (British English; in American English, people usually say I have a bike.)
- She has a bike. → She’s got a bike. (very common in speaking)
- He has had enough. → He’s had enough.
- They had a plan.
Quick Examples (Different Meanings)

- Present perfect (auxiliary): She has seen that movie. / We have eaten dinner already.
- Obligation (have to): I have to go now. / He has to work today.
Has / Have for Possession
Using Has and Have for Possession
The primary meaning of “have” is to possess, own, or contain. Use has with he/she/it, and have with I/you/we/they and plural subjects.
- I have a car.
- She has a cat.
- They have a house.
Third-Person Singular (Has)
When the subject is he, she, or it, we use has.
- He has a bike.
- She has a book.
- The company has a website.
Using Has and Have with Pronouns
You can also use “have/has” with pronouns to show possession.
- I have mine.
- You have yours.
- He has his.
- She has hers.
- It has its.
- We have ours.
- They have theirs.
Has / Have as Auxiliary Verbs (Present Perfect)
Using Have as an Auxiliary Verb
As an auxiliary verb, “have/has” is used to form the present perfect:
have/has + past participle.
- We have eaten dinner already.
- She has seen that movie before.
- They have not started yet.
- He has been studying for hours.
Note: In “present perfect,” has/have does not mean possession. It helps the main verb show time.
Have to (Obligation)
“Have to” expresses obligation or necessity. It is sometimes called a semi-modal (not a true modal verb).
- We have to finish our homework before we can watch TV.
- She has to be at work by 9 AM.
Common Mistakes
- Mistake 1: Using has with I/you/we/they.
Wrong: I has a car.
Correct: I have a car. - Mistake 2: Using have with he/she/it.
Wrong: She have a cat.
Correct: She has a cat. - Mistake 3: Thinking “have” is a modal verb.
Correction: In sentences like “She could have taken the day off,” the modal is could. “Have” is an auxiliary verb in the structure modal + have + past participle.
