1. Definition: What are Third Person Singular Verbs?
Third-person singular verbs are verb forms used when the subject of a sentence is a singular noun or pronoun in the third person. In English, the third person singular pronouns are he, she, and it. These pronouns refer to someone or something that is not the speaker (first person) or the person being spoken to (second person). The verb form changes in the present simple tense when used with these subjects.
The primary characteristic of third-person singular verbs in the present simple tense is the addition of an -s or -es to the base form of the verb. This grammatical rule helps to distinguish third-person singular subjects from other subjects. For example, “I walk” becomes “He walks,” and “They eat” changes to “She eats.” Understanding this change is essential for constructing grammatically correct sentences.
The function of third-person singular verbs is to indicate an action or state being performed by a single entity that is neither the speaker nor the person being addressed. This is a fundamental aspect of subject-verb agreement in English grammar.
Without proper subject-verb agreement, sentences can sound awkward or be misinterpreted. Therefore, mastering the use of third-person singular verbs is crucial for clear and effective communication.
2. Structural Breakdown of Third Person Singular Verbs
The structure of third-person singular verbs is relatively straightforward. In the present simple tense, the base form of the verb is modified by adding either an -s or -es. The choice between adding -s or -es depends on the ending of the base verb. This modification only occurs in the present simple tense; other tenses do not require this change.
Here’s a breakdown of the rules for adding -s or -es:
- Most verbs: Add -s to the base form. For example, walk becomes walks, and eat becomes eats.
- Verbs ending in -s, -ss, -sh, -ch, -x, or -z: Add -es. For example, kiss becomes kisses, wash becomes washes, watch becomes watches, fix becomes fixes, and buzz becomes buzzes.
- Verbs ending in a consonant + -y: Change the -y to -i and add -es. For example, study becomes studies, and cry becomes cries. However, if the verb ends in a vowel + -y, simply add -s (e.g., play becomes plays).
- The verb “have”: This is an irregular case. The third-person singular form of have is has.
- The verb “do”: The third-person singular form of do is does.
- The verb “go”: The third-person singular form of go is goes.
Understanding these rules is essential for correctly conjugating verbs in the third-person singular form. Proper application of these rules ensures that your sentences are grammatically sound and clear.
3. Types and Categories of Verbs
Verbs can be categorized into different types based on their behavior and function in a sentence. Understanding these categories helps in applying the correct rules for third-person singular conjugation.
The primary categories include regular verbs, irregular verbs, and auxiliary verbs.
3.1. Regular Verbs
Regular verbs are those that follow a predictable pattern when conjugated. In the context of third-person singular verbs, regular verbs typically add -s or -es to the base form in the present simple tense. These verbs are easier to learn and use because their conjugation follows a consistent rule.
Examples of regular verbs include walk, talk, work, and play. When used in the third-person singular form, they become walks, talks, works, and plays, respectively. The consistent pattern makes these verbs straightforward to conjugate correctly.
3.2. Irregular Verbs
Irregular verbs do not follow the standard rules of conjugation. Their forms in different tenses, including the third-person singular, are often unique and must be memorized.
These verbs can be challenging for English learners because they do not conform to a predictable pattern.
Common irregular verbs include be, have, do, and go. Their third-person singular forms are is, has, does, and goes, respectively. Because these forms are not derived from the base verb by simply adding -s or -es, they require specific attention and memorization.
3.3. Auxiliary Verbs
Auxiliary verbs, also known as helping verbs, are used in conjunction with main verbs to form tenses, moods, and voices. The auxiliary verbs be, have, and do have distinct third-person singular forms that must be used correctly.
For example, the verb be becomes is in the third-person singular (e.g., He is). The verb have becomes has (e.g., She has), and the verb do becomes does (e.g., It does). Understanding the correct forms of these auxiliary verbs is crucial for constructing complex sentences and using various tenses accurately.
4. Examples of Third Person Singular Verbs

5. Usage Rules for Third Person Singular Verbs
Using third-person singular verbs correctly requires understanding several rules and exceptions. These rules govern how verbs are conjugated in the present simple tense when the subject is he, she, or it.
5.1. Basic Rules
The fundamental rule is that most verbs add -s to the base form when used with a third-person singular subject in the present simple tense. This rule applies to the majority of verbs and is the foundation for correct conjugation.
For verbs ending in -s, -ss, -sh, -ch, -x, or -z, add -es instead of just -s. This ensures proper pronunciation and grammatical correctness. For example, “He watches TV” instead of “He watchs TV.”
For verbs ending in a consonant followed by -y, change the -y to -i and add -es. For example, “She studies hard” instead of “She studys hard.” However, if the verb ends in a vowel followed by -y, simply add -s (e.g., “He plays the piano”).
5.2. Exceptions to the Rules
Some verbs do not follow the standard rules for third-person singular conjugation. These exceptions must be memorized to avoid errors.
The verb have is irregular. Its third-person singular form is has, not haves. For example, “She has a book” instead of “She haves a book.”
The verb be is also irregular. Its third-person singular form is is, not bes. For example, “He is a teacher” instead of “He bes a teacher.”
The verb do is another exception. Its third-person singular form is does, not dos. For example, “It does not work” instead of “It dos not work.”
5.3. Special Cases
There are some special cases where the rules for third-person singular verbs may seem unclear. These cases often involve collective nouns or indefinite pronouns.
Collective nouns (e.g., team, family, group) can be treated as singular or plural depending on the context. If the collective noun is acting as a single unit, use a singular verb. If the members of the group are acting individually, use a plural verb. For example, “The team plays well together” (singular) versus “The team are arguing among themselves” (plural).
Indefinite pronouns such as everyone, everybody, someone, and nobody are generally treated as singular. Therefore, they require a third-person singular verb. For example, “Everyone likes ice cream” instead of “Everyone like ice cream.”
When using the phrase “there is” or “there was,” the verb must agree with the noun that follows. If the noun is singular, use “there is” or “there was.” If the noun is plural, use “there are” or “there were.” For example, “There is a book on the table” (singular) versus “There are books on the table” (plural).
6. Common Mistakes with Third Person Singular Verbs
Several common mistakes can occur when using third-person singular verbs. Recognizing and avoiding these errors is crucial for improving grammar proficiency.
Incorrect: He walk to school.
Correct: He walks to school.
Incorrect: She have a car.
Correct: She has a car.
Incorrect: It do not work.
Correct: It does not work.
Incorrect: The cat like to sleep.
Correct: The cat likes to sleep.
Incorrect: Everyone like the movie.
Correct: Everyone likes the movie.
Incorrect: She study every night.
Correct: She studies every night.
Incorrect: He watch TV.
Correct: He watches TV.
Incorrect: It rain a lot.
Correct: It rains a lot.
Incorrect: She go to the store.
Correct: She goes to the store.
Incorrect: The dog bark loudly.
Correct: The dog barks loudly.
Another common mistake is using the base form of the verb instead of the correct third-person singular form. This often happens when learners forget to add the -s or -es ending. Always double-check that the verb agrees with the subject.
Forgetting to change the -y to -i and add -es for verbs ending in a consonant + -y is also a frequent error. Remember to apply this rule consistently to avoid mistakes.
Confusing the forms of irregular verbs is another common issue. Make sure to memorize the correct third-person singular forms of these verbs to ensure accuracy.

8. Advanced Topics
For advanced learners, understanding the nuances of third-person singular verbs in more complex grammatical structures is essential. This includes conditional sentences, subjunctive mood, and inverted sentences.
In conditional sentences, the rules for third-person singular verbs remain the same in the main clause. For example, “If he studies hard, he will pass the exam.”
The subjunctive mood often uses the base form of the verb, even with third-person singular subjects. This is common in formal writing and expressions of wishes, suggestions, or commands.
For example, “It is essential that he be present at the meeting.”
Inverted sentences, where the subject follows the verb, the verb must still agree with the subject. For example, “There goes the bus” (singular) versus “Here come the students” (plural).
Understanding these advanced topics allows for more sophisticated and accurate use of third-person singular verbs in various contexts. Continued practice and exposure to advanced grammatical structures will further enhance proficiency.
9. Frequently Asked Questions (FAQ)
Here are some frequently asked questions about third-person singular verbs, along with detailed answers to clarify common points of confusion.
Q1: Why do we need to add -s or -es to verbs in the third-person singular?
A: Adding -s or -es to verbs in the third-person singular is a grammatical convention in English to indicate subject-verb agreement. It helps distinguish third-person singular subjects (he, she, it) from other subjects in the present simple tense. This distinction is crucial for clarity and grammatical correctness.
Q2: What if the subject is a singular noun instead of a pronoun?
A: If the subject is a singular noun (e.g., the cat, John, the book), the same rules for third-person singular verbs apply. The verb must agree with the singular noun. For example, “The cat sleeps on the mat” and “John works at the bank.”
Q3: How do I know when to use -s or -es?
A: The choice between adding -s or -es depends on the ending of the base verb. Add -es to verbs ending in -s, -ss, -sh, -ch, -x, or -z. For verbs ending in a consonant + -y, change the -y to -i and add -es. In all other cases, add -s.
Q4: Are there any verbs that never change in the third-person singular?
A: Most verbs change in the third-person singular in the present simple tense. However, modal auxiliary verbs (e.g., can, will, should, must) do not change form regardless of the subject. For example, “He can swim” and “She will arrive soon.”
Q5: What about compound subjects? Do they take a singular or plural verb?
A: If a compound subject is joined by “and,” it generally takes a plural verb. For example, “John and Mary are going to the party.” However, if the compound subject refers to a single entity or idea, it takes a singular verb. For example, “Macaroni and cheese is my favorite dish.”
Q6: How do collective nouns affect third-person singular verb usage?
A: Collective nouns can be tricky. If the collective noun is acting as a single unit, use a singular verb. If the members of the group are acting individually, use a plural verb. For example, “The team plays well together” (singular) versus “The team are arguing among themselves” (plural).
Q7: What is the third person singular of the verb “to be”?
A: The third person singular form of the verb “to be” is “is”. For example, “He is a student”, “She is happy”, and “It is raining”.
