What Is a Subjective Complement?
A subjective complement—often called a subject complement—is a word or phrase that follows a linking verb and provides additional information about the subject of the sentence. That said, it completes the meaning of the verb by describing or renaming the subject, functioning similarly to an adjective or a noun in its role. Understanding subjective complements is essential for mastering sentence structure, avoiding grammatical errors, and writing clear, expressive prose.
The Anatomy of a Subjective Complement
Linking Verbs: The Gatekeepers
The first requirement for a subjective complement is a linking verb. Linking verbs connect the subject to the complement and do not express action. Common linking verbs include:
- be (am, is, are, was, were)
- seem, appear, become
- feel, look, taste, smell, sound
- remain, prove, turn, grow, stay
These verbs signal that the complement will describe the subject rather than the object.
Predicate Adjectives vs. Predicate Nominatives
Subjective complements come in two primary forms:
| Type | Function | Example |
|---|---|---|
| Predicate Adjective | Describes the subject’s state or quality | The sky is blue. |
| Predicate Nominative | Renames the subject with a noun or pronoun | He became a teacher. |
It sounds simple, but the gap is usually here.
Both are called predicate because they appear in the predicate (the part of the sentence following the subject).
Placement Rules
-
After the linking verb – The complement follows the verb directly.
She seems tired after the trip. -
Same subject – The complement refers back to the same subject, not an object.
The problem is simple. (not is simple to solve) -
No direct object – Linking verbs do not take a direct object, so the complement cannot be an object.
He likes coffee. → He likes coffee (object), He looks happy. (subjective complement)
Examples That Illustrate the Concept
| Sentence | Linking Verb | Complement Type | What It Complements |
|---|---|---|---|
| *The soup tastes delicious.Even so, * | tastes | Predicate Adjective | soup |
| *She is a genius. And * | is | Predicate Nominative | she |
| *The movie appears too long. * | appears | Predicate Adjective | movie |
| *The team became champions. |
Notice how each complement answers the question “What is the subject?” or “What does the subject become?”
Subjective Complement vs. Object Complement
| Feature | Subjective Complement | Object Complement |
|---|---|---|
| Subject vs. That's why object | Refers to the subject | Refers to the object |
| Verb type | Linking verb | Action verb |
| Function | Describes the subject | Renames or modifies the object |
| Example | *The cake tastes sweet. * | *They named the dog Max. |
People argue about this. Here's where I land on it.
A common mistake is confusing the two. Remember: if the complement follows an action verb and refers to the object, it’s an object complement; otherwise, it’s a subjective complement.
How to Identify a Subjective Complement in Practice
- Locate the linking verb.
- Check the subject.
- See if the following phrase describes or renames that subject.
- Ensure no direct object is present.
Quick Test
- Replace the complement with a synonym.
The sky is blue. → The sky is azure. (still works)
He became a teacher. → He became a professor. (still works)
If the sentence still makes sense and the complement refers to the subject, you’ve found a subjective complement.
Common Mistakes and How to Avoid Them
-
Using a direct object after a linking verb
❌ She looks the new manager.
✅ She looks like the new manager. -
Confusing subjective and object complements
❌ They painted the room white. (action verb)
✅ The room is white. (linking verb) -
Misplacing the complement
❌ The teacher is the student’s proud.
✅ The teacher is proud of the student. -
Forgetting to use a linking verb
❌ The concert excited everyone.
✅ The concert excited everyone. (action verb) → Everyone felt excited by the concert. (linking verb)
Frequently Asked Questions
What verbs can be used as linking verbs?
Linking verbs include be, seem, appear, become, feel, look, taste, smell, sound, remain, prove, turn, grow, and stay. Any verb that connects the subject to an adjective or noun without expressing action qualifies.
Can a subjective complement be a phrase?
Yes. A complement can be an adjective phrase (as tired as ever), a noun phrase (a wonderful surprise), or even a clause (to be the best). The key is that it refers back to the subject.
Are subjective complements only used in simple sentences?
No. In real terms, they can appear in compound or complex sentences. *Although the weather was bad, the team remained enthusiastic.
How do I know if a verb is a linking verb or an action verb?
If the verb does not transfer action to an object and the sentence feels descriptive rather than active, it’s likely a linking verb. Even so, for instance, The soup smells good (linking) vs. The chef smells the soup (action).
What is the difference between a predicate adjective and a predicate nominative?
A predicate adjective modifies the subject with an adjective (e.g.Day to day, , The cake is sweet). Because of that, g. A predicate nominative renames the subject with a noun or pronoun (e., The cake is a dessert) Practical, not theoretical..

Practical Exercises
Below are three short passages followed by a set of sentences. For each sentence, identify the linking verb (if present) and label the subjective complement as either a predicate adjective (PA) or a predicate nominative (PN) It's one of those things that adds up. Practical, not theoretical..
Passage A
The old library stood at the corner of Maple Street, its windows shrouded in dust. Inside, the air felt stale, and the shelves were a chaotic maze of forgotten tomes.
| # | Sentence | Linking Verb | Subjective Complement | Type |
|---|---|---|---|---|
| 1 | The old library stood at the corner of Maple Street. Which means | — | — | — |
| 2 | The air felt stale. | felt | stale | PA |
| 3 | The shelves were a chaotic maze of forgotten tomes. | were | a chaotic maze of forgotten tomes | PN |
| 4 | The windows shrouded in dust. |
Explanation: Sentence 1 uses stood as an action verb (the library performed the action of standing). Sentence 4 lacks a linking verb; shrouded is a participial adjective modifying windows, not a complement.
Passage B
After months of training, Maya became the team’s most reliable defender. Her teammates considered her a rock, and the coach found her performance impressive Small thing, real impact..
| # | Sentence | Linking Verb | Subjective Complement | Type |
|---|---|---|---|---|
| 1 | Maya became the team’s most reliable defender. Even so, | became | the team’s most reliable defender | PN |
| 2 | Her teammates considered her a rock. | — | — | — |
| 3 | The coach found her performance impressive. | found | impressive | PA |
| 4 | Her performance impressive. |
Explanation: In sentence 2, considered is an action verb that takes a direct object (her). Sentence 4 is a fragment; it needs a linking verb such as was to become grammatical.
Passage C
The sunrise appears golden today, and the meadow looks serene. By noon, the heat will become unbearable, but the breeze remains gentle.
| # | Sentence | Linking Verb | Subjective Complement | Type |
|---|---|---|---|---|
| 1 | The sunrise appears golden today. | appears | golden | PA |
| 2 | The meadow looks serene. Also, | become | unbearable | PA |
| 4 | The breeze remains gentle. | looks | serene | PA |
| 3 | The heat will become unbearable. | remains | gentle | PA |
| 5 | The meadow looks the sunrise. |
Explanation: Sentence 5 misuses the linking verb; looks needs a preposition (like or as) to form a proper complement.
Answer Key
- Passage A: 2 PA, 3 PN
- Passage B: 1 PN, 3 PA
- Passage C: 1 PA, 2 PA, 3 PA, 4 PA

Answer Key
| # | Correct Answer | Explanation |
|---|---|---|
| 1 | B – engaging describes the subject lecture; it is a predicate adjective (PA). | |
| 2 | B – taste links carrots to the adjective sweet (PA). Think about it: | |
| 3 | A – grew functions as a linking verb connecting night to silent. Here's the thing — | |
| 4 | False – Only certain verbs can serve as linking verbs; the presence of a complement alone does not convert an action verb into a linking verb. | |
| 5 | B – undecided describes the subject committee; it is a predicate adjective. Worth adding: | |
| 6 | B – looks needs a preposition (like or as) to compare; without it the sentence is a misuse of the linking verb. Here's the thing — | |
| 7 | B – the team captain renames the subject He; it is a predicate nominative (PN). | |
| 8 | C – run is a pure action verb and cannot act as a linking verb. | |
| 9 | B – tired describes She; it is a predicate adjective. | |
| 10 | B – looks is a linking verb that requires a complement; the sentence should read “The river looks like the mountains” or use an action verb such as “The river reflects the mountains. |
Common Pitfalls & How to Avoid Them
| Pitfall | Why It Happens | Quick Fix |
|---|---|---|
| Confusing “look” with “see” | Look can be both an action verb (look at the board) and a linking verb (The sky looks gray). | |
| Leaving out the linking verb | Students sometimes write “She a teacher,” omitting is/was. Plus, * If yes, it’s likely a linking verb. Now, | |
| Using a noun as a complement after a linking verb | Nouns can be complements, but they must rename the subject (PN). | Verify that the noun refers back to the subject; otherwise, you need an adjective. |
| Mistaking a predicate adjective for a direct object | Both can follow a verb, but a direct object receives the action. |
| Pitfall | Why It Happens | Quick Fix |
|---|---|---|
| Confusing “look” with “see” | Look can be both an action verb (look at the board) and a linking verb (The sky looks gray). | Ask yourself: Is there a complement that describes the subject? If yes, it’s likely a linking verb. |
| Leaving out the linking verb | Students sometimes write “She a teacher,” omitting is/was. | Insert the appropriate form of be (or another linking verb) before the complement. |
| Using a noun as a complement after a linking verb | Nouns can be complements, but they must rename the subject (PN). On top of that, | Verify that the noun refers back to the subject; otherwise, you need an adjective. |
| Mistaking a predicate adjective for a direct object | Both can follow a verb, but a direct object receives the action. | Replace the verb with an action verb (eat, build)—if the sentence still makes sense, the complement is a predicate adjective. |
Mastering Linking Verbs: A Practical Guide
Understanding linking verbs is crucial for constructing grammatically correct and clear sentences. In real terms, as we’ve explored, these verbs differ significantly from action verbs, which express an action performed by the subject. They connect the subject of a sentence to a word or phrase that describes or identifies it, rather than showing an action. The key difference lies in their function: linking verbs relate, while action verbs do.
Let’s revisit some common errors and reinforce the principles. Remember, the presence of a complement – a noun or adjective that follows a linking verb – doesn’t automatically make a verb a linking verb. Practically speaking, it’s the function of that complement that determines whether the verb is linking. Consider the sentence, “The soup smells delicious.” Here, “smells” is a linking verb connecting “soup” to the adjective “delicious,” which describes the soup Small thing, real impact. Practical, not theoretical..
Adding to this, the “look” verb presents a persistent challenge. As highlighted in the pitfalls, it’s a versatile word. Distinguishing between its action and linking forms requires careful consideration of the sentence’s structure and the role of the complement. Don’t simply assume it’s an action verb; look for the descriptive element that follows it.
Finally, remember that not all verbs can function as linking verbs. Verbs like “run,” “jump,” and “think” are strictly action verbs and cannot be used in this way.
So, to summarize, mastering linking verbs requires a nuanced understanding of their function and a willingness to analyze sentence structure. Here's the thing — by focusing on the relationship between the subject and the complement, and by recognizing the distinct characteristics of linking versus action verbs, you can significantly improve your writing and communication skills. Continual practice and attention to detail will solidify your grasp of this fundamental grammatical concept.
