When it comes to English grammar, the difference between “has” and “have” seems simple, but it can easily confuse learners. Whether you’re writing an essay, giving a presentation, or simply chatting with friends, knowing when to use “has” and “have” can elevate your communication. So, let’s break down the nuances of these two verbs to help you get it right every time.
Understanding “Has” vs. “Have” in English Grammar
At its core, “has” and “have” are forms of the verb “to have,” and they both function as auxiliary verbs or main verbs depending on the context. The confusion typically arises because English speakers use these two forms in different ways based on the subject of the sentence.
What’s the Difference Between “Has” and “Have”?
- “Has” is used with third-person singular subjects like he, she, or it.
- Example: She has a cat.
- “Have” is used with first-person singular subjects (I), second-person singular/plural subjects (you), and all plural subjects.
- Example: They have a dog.
It’s simple, right? The tricky part comes in understanding subject-verb agreement and how to apply this rule in different sentence structures.
Subject-Verb Agreement: The Foundation
Subject-verb agreement is one of the cornerstones of English grammar. It ensures that the subject of a sentence matches its verb in terms of number and person. In other words, singular subjects must pair with singular verbs, and plural subjects must pair with plural verbs.
Singular vs. Plural Subjects
- Singular subject + singular verb = has
- She has the keys.
- John has finished his homework.
- Plural subject + plural verb = have
- They have finished their homework.
- We have the same goals.
It’s important to remember that “has” applies to singular subjects in the third person (she, he, it), and “have” is used for all other subjects, including I, you, we, they, and plural nouns.
When to Use “Has” in a Sentence
The use of “has” is typically tied to the subject being singular and in the third person. Here are some situations where “has” should be used.
With Third-Person Singular Subjects

- Example: She has a beautiful voice.
Examples in Different Sentence Structures

Special Cases and Exceptions
English grammar is rarely straightforward, and there are a few cases where things can get a little tricky. Let’s explore some of those exceptions.
Collective Nouns: “The Team Has” vs. “The Players Have”
When we refer to a group or collective noun, things change slightly. The rule is that collective nouns, like “team,” “family,” or “group,” are treated as singular when you focus on them as a unit.
- The team has won the match.
- The family has moved to a new house.
However, when you emphasize the individuals in the group, you use the plural form:
- The players have left the field.
Proper Nouns and Names: Why “Sarah Has” is Correct
Proper nouns, such as names, always follow the same rule as other singular subjects. If the subject is a singular name, “has” is appropriate.
- Sarah has a great sense of humor.
- John has been working hard on the project.
Perfect Tenses: Using “Has” and “Have” in Compound Tenses
In English, we use perfect tenses to describe actions that are completed or that have a connection to the present. The auxiliary verbs “has” and “have” are used to form these tenses.
Present Perfect: “She Has Gone” vs. “I Have Gone”
The present perfect tense is used to describe actions that occurred at an indefinite time in the past but have relevance to the present.
- She has gone to the store (She went, and she is still at the store, or the action affects the present).
- I have seen that movie before.
Past Perfect: How “Had” Fits into the Picture
The past perfect tense describes an action that was completed before another action in the past.
- By the time I arrived, they had left.
Future Perfect: When “Will Have” Applies
The future perfect tense expresses an action that will be completed before a specific point in the future.
- By next month, we will have finished the project.
Modal Verbs: Why “She Should Have” Is Correct (Not “She Should Has”)
Modal verbs like “should,” “could,” “would,” and “might” don’t change based on the subject. What’s interesting is that modals are always followed by the base form of a verb — in this case, “have,” not “has.”
Why “Should Have” and Not “Should Has”?
- Correct: She should have gone to the doctor.
- Incorrect: She should has gone to the doctor.
This rule applies to all modals. Some other examples:
- She could have done it.
- He might have missed the train.
