What is Subject Complement in Grammar?
A subject complement in grammar is a word or phrase that gives more information about the subject of a sentence. It follows a linking verb such as is, are, was, were, seems, feels, or becomes and helps define, describe, or rename the subject. Subject complements do not show action but instead provide clarity about the subject.
Example of Subject Complement:
She is a doctor.
Explanation:
In this sentence, “doctor” is the subject complement because it follows the linking verb “is” and describes the subject “She.” A subject complement either renames (predicate nominative) or describes (predicate adjective) the subject. Here, “doctor” renames “She,” making it a predicate nominative.

Predicate Pronouns | A pronoun that acts as a subject complement after a linking verb. | The author of the book is he. |

Noun Phrase as Subject Complements | A group of words containing a noun that renames the subject. | His dream is to become a scientist. |

How To Identify Subject Complement?
Identifying subject complement in grammar can seem tricky at first, but by following a few simple steps, one can become a pro in no time!
Steps 1. Find the Subject
The first step is to locate the subject of the sentence. Remember, the subject is the person, place, thing, or idea that the sentence is about.
Example: The cake is delicious.
Explanation: In the sentence The cake is delicious, the subject is The cake because it is the main focus of the sentence. It tells us what the sentence is about and connects to the rest of the statement through the linking verb is.
Step 2. Locate the Linking Verb
Next, identify the linking verb. Linking verbs connect the subject to the subject complement. Common linking verbs include forms of “be” (is, are, was, were, am, been), become, seem, appear, feel, look, taste, smell, and sound.
Example: The cake is delicious.
Explanation: In the sentence The cake is delicious, the linking verb is is because it connects the subject (The cake) to the subject complement (delicious), describing its state or quality.
Step 3: Identify the Word or Phrase After the Linking Verb
Look at the word or phrase that comes immediately after the linking verb. This is your potential subject complement.
Example: The cake is delicious.
Explanation: In the sentence The cake is delicious, the word after the linking verb is is delicious. It serves as the subject complement in grammar, describing the quality of the cake.
Step 4: Check if it Renames or Describes the Subject:
- This is an important step. Ask yourself: Does the word or phrase after the linking verb rename or describe the subject?
- If it does, it is a subject complement.
- If it renames the subject, it is a Predicate Nominative.
- If it describes the subject, it is a Predicate Adjective.
Example: The cake is delicious.
Explanation: Delicious describes the cake, so it is a predicate adjective.
Step 5: The To Be Test (Helpful Tip)
If you can replace the linking verb with a form of the verb to be and the sentence still makes logical sense, you are most likely dealing with a subject complement.
Example: The cake is delicious.
Explanation: In The cake is delicious, applying the To Be Test confirms that delicious is the subject complement. The linking verb is connects cake to delicious, which describes the cake, making it a predicate adjective.
What is Copula/Copula Verb?
A copula verb, also known as a linking verb, is a verb that connects the subject of a sentence to a subject complement (a word or phrase that describes or identifies the subject). Unlike action verbs, copula verbs do not show any physical or mental activity but express a state of being or condition.
Common Coupla Verbs:
Some of the Common Coupla Verbs are given below:
Be Vebs | is, am, are, was, were, be, been |
Sense Verbs | seem, look, feel, sound, taste, smell |
Becoming Verbs | become, grow, turn, remain, stay |
Other Copulas | get, keep, go, act, stand, fall (in specific contexts) |
Example:
She remained calm during the storm.
Explanation: The verb remained is a copula verb that links she (subject) to calm (adjective, describing her state). Remained functions like was here, showing her state of being during the storm.

FAQs
Ans. A complement is a word or phrase that completes the meaning of a sentence by adding information about the subject or object.
Examples:
1. She is a doctor. (Subject complement)
2. They named him captain. (Object complement)
Ans. A linking verb connects the subject of a sentence to additional information without expressing an action. It helps describe the subject’s state or identity. In contrast, a subject complement follows a linking verb and either renames or describes the subject, completing the sentence’s meaning. For example, in the sentence The food smells delicious, the verb “smells” acts as a linking verb because it connects the subject “food” to the adjective “delicious,” which serves as the subject complement by describing the food. Common linking verbs include is, are, was, were, become, seem, look, and appear, while subject complements can be nouns or adjectives, such as a doctor, happy, tired, or intelligent.
Ans. Here are five sentences with subject complements:
1. The sky looks blue. (Adjective)
2. She became a writer. (Noun)
3. The soup smells delicious. (Adjective)
4. He was my best friend. (Noun)
5. They seem tired. (Adjective)
Ans. To identify a subject complement, follow these steps:
Find the subject of the sentence.
1. Locate the linking verb (is, are, was, were, seem, become, and look.)
