A subject pronoun replaces the noun that performs the action of a verb, such as I, you, he, she, it, we and they. It is usually the first type of pronoun learners encounter, and the basic list is easy to memorize. However, mistakes can still occur in more complex sentences, with compound subjects, or when choosing between formal and informal forms such as “It is I” and “It’s me.”
This article explains the definition of this grammatical form, its position in a sentence, its relationship with possessive adjectives, how the singular “they” works, and includes practice exercises with answers.
What is a subject pronoun?
Definition
A subject pronoun is a pronoun that functions as the subject of a verb, performing the action or being described by it.
Example: She works in a hospital. – “She” is the subject, performing the action of working.
Why subject pronouns matter
Using one of these forms in place of a repeated noun makes sentences shorter and more natural. Choosing the correct form is essential in English because, unlike some languages, English generally requires an explicit subject in every complete sentence.
Compare: Sarah is tired. Sarah wants to go home. → Sarah is tired. She wants to go home.
List of subject pronouns
| Person | Singular | Plural |
| First person | I | we |
| Second person | you | you |
| Third person | he, she, it | they |
Note that “I” is always capitalized, wherever it appears in a sentence, and that you has the same form for singular and plural.
Where subject pronouns go in a sentence
In statements: before the verb
In a statement, the subject pronoun normally comes before the verb.
Example: They play football every weekend.
In questions: after the auxiliary verb
In questions, the subject pronoun usually moves after the auxiliary or modal verb.
Example: Do you like coffee? Can she swim?
After “than” and “as” in formal comparisons
In formal English, a subject pronoun follows “than” or “as” when the pronoun is the subject of an implied verb.
Example: He is taller than I (am). She works as hard as he (does).
In casual speech, the object form (than me, as him) is common, but the subject pronoun form is preferred in formal writing.
Subject pronoun and possessive adjective
Each subject pronoun has a related possessive adjective, which shows ownership and comes before a noun. Learners often confuse the two groups, so it helps to see them side by side.
| Subject pronoun | Possessive adjective | Example |
| I | my | I lost my keys. |
| you | your | You forgot your umbrella. |
| he | his | He called his mother. |
| she | her | She finished her homework. |
| it | its | It wagged its tail. |
| we | our | We love our teacher. |
| they | their | They sold their car. |
The subject pronoun acts as the subject of the verb, while the possessive adjective modifies a noun, so the two cannot be swapped. Writing Me lost I keys or He called he mother mixes up the grammatical roles and produces an incorrect sentence.
Subject pronoun “they”
Plural “they”
The most common use of subject pronoun they is as a plural, referring to more than one person or thing.
Example: The students finished early, so they left.
Singular “they”
“They” is also widely used as a singular pronoun, either for a person whose gender is unknown or unspecified, or for someone who uses “they” as their personal pronoun. This use is well established in modern English and recognized by major style guides.
Examples: Someone left their umbrella here. (unknown person) Alex said they would join us later. (a person who uses “they”)
With singular “they,” the verb still takes the plural form, as in “They are coming,” not “They is coming.”
Subject pronoun and object pronoun
Because most pronouns used as subjects have a different object form (he becomes him, they becomes them), learners are often tested on the distinction between subject and object pronouns. The subject form performs the action and comes before the verb, while the object form receives the action. A fuller comparison, including direct and indirect objects and pronouns used after prepositions, is covered in our article on object pronouns, linked at the end of this page.
Example: She called him. (She = subject pronoun, him = object pronoun)
Special cases
“It” and “there” as dummy subjects
English often needs a subject even when there is no real performer of the action, so “it” and “there” are used as placeholder subjects.
Examples: It is raining. It is important to study. There is a book on the table.
In these sentences, “it” and “there” do not refer to a specific thing; they exist to fill the subject position that English grammar requires.
“It is I” versus “It’s me”
After the verb “to be,” formal grammar traditionally calls for the subject pronoun form, as in “It is I,” while everyday speech overwhelmingly uses the object form, “It’s me.” Both are understood, but “It is I” can sound stiff or overly formal in conversation, so the choice depends on the context and level of formality.
Common mistakes with subject pronouns
- Using an object form as a subject. Writing Me and him went to the store instead of He and I went to the store.
- Forgetting to capitalize “I.” Writing “i think so” instead of “I think so,” since “I” is always capitalized in standard English.
- Dropping the subject in a sentence that requires one. Writing Is raining instead of It is raining, a common mistake for learners whose first language allows sentences without an explicit subject.
- Repeating the subject unnecessarily. Writing My brother he lives in Canada instead of My brother lives in Canada, doubling the subject by using both a noun and a pronoun.
- Confusing subject forms with possessive adjectives. Writing Their going to the party instead of They’re going to the party, or He lost him keys instead of He lost his keys.
Subject pronoun exercises with answers
Exercise 1: Choose the correct subject pronoun
- ______ (She / Her) is a doctor at the local hospital.
- My friends and ______ (I / me) are going to the beach.
- ______ (They / Them) are waiting outside.
- ______ (It / There) is a lot of traffic today.
Sample answers: 1. She – 2. I – 3. They – 4. There
Exercise 2: Replace the noun with a subject pronoun
- Maria and John are late. → They are late.
- The cat is sleeping. → It is sleeping.
- My sister and I are visiting Paris. → We are visiting Paris.
Exercise 3: Find and correct the error
- Me and him are friends. → correct to He and I are friends.
- Is cold outside today. → correct to It is cold outside today.
- My mother she works at a school. → correct to My mother works at a school.
Subject pronoun worksheets and games for practice
A subject pronoun worksheet typically includes the exercise types above: multiple choice, noun replacement, and error correction, often alongside a short list of these forms so learners can check their answers. A worksheet covering both subject and object pronouns extends the same practice to both groups, helping learners understand how pronouns change depending on their grammatical role. Additional grammar exercises and a pronoun game, such as a matching card activity where players pair a noun phrase with the correct form, can make repeated practice more engaging, especially for younger learners.
These pronouns replace nouns that perform the action of a verb. The main skills are choosing the correct form for the person and number, placing it correctly in statements and questions, and distinguishing it from object pronouns and possessive adjectives. Understanding special cases, such as the singular “they” and dummy subjects like “it” and “there,” covers most situations in which learners may have difficulty using these forms.
