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. Here's the thing — 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 The details matter here..
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. |
Both are called predicate because they appear in the predicate (the part of the sentence following the subject) Small thing, real impact..
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. | tastes | Predicate Adjective | soup |
| She is a genius. | 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. Also, 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. |
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 Practical, not theoretical..
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 Small thing, real impact..
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. Because of that, 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. In practice, for instance, The soup smells good (linking) vs. The chef smells the soup (action) Took long enough..
What is the difference between a predicate adjective and a predicate nominative?
A predicate adjective modifies the subject with an adjective (e.g., The cake is sweet). A predicate nominative renames the subject with a noun or pronoun (e.g., The cake is a dessert).

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) Turns out it matters..
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. | — | — | — |
| 2 | The air felt stale. Plus, | 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 That's the whole idea..
| # | Sentence | Linking Verb | Subjective Complement | Type |
|---|---|---|---|---|
| 1 | Maya became the team’s most reliable defender. | 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 And that's really what it comes down to..
Passage C
The sunrise appears golden today, and the meadow looks serene. By noon, the heat will become unbearable, but the breeze remains gentle And that's really what it comes down to..
| # | Sentence | Linking Verb | Subjective Complement | Type |
|---|---|---|---|---|
| 1 | The sunrise appears golden today. Practically speaking, | become | unbearable | PA |
| 4 | The breeze remains gentle. | looks | serene | PA |
| 3 | The heat will become unbearable. | appears | golden | PA |
| 2 | The meadow looks serene. | 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). | |
| 7 | B – the team captain renames the subject He; it is a predicate nominative (PN). | |
| 2 | B – taste links carrots to the adjective sweet (PA). Even so, | |
| 6 | B – looks needs a preposition (like or as) to compare; without it the sentence is a misuse of the linking verb. | |
| 3 | A – grew functions as a linking verb connecting night to silent. | |
| 8 | C – run is a pure action verb and cannot act as a linking verb. Plus, | |
| 5 | B – undecided describes the subject committee; it is a predicate adjective. Also, | |
| 9 | B – tired describes She; it is a predicate adjective. | |
| 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. | |
| 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). Now, | Verify that the noun refers back to the subject; otherwise, you need an adjective. * 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). | Ask yourself: *Is there a complement that describes the subject? |
| Mistaking a predicate adjective for a direct object | Both can follow a verb, but a direct object receives the action. |

Mastering Linking Verbs: A Practical Guide
Understanding linking verbs is crucial for constructing grammatically correct and clear sentences. Worth adding: they connect the subject of a sentence to a word or phrase that describes or identifies it, rather than showing an action. As we’ve explored, these verbs differ significantly from action verbs, which express an action performed by the subject. The key difference lies in their function: linking verbs relate, while action verbs do.
No fluff here — just what actually works.
Let’s revisit some common errors and reinforce the principles. And consider the sentence, “The soup smells delicious. On the flip side, it’s the function of that complement that determines whether the verb is linking. Remember, the presence of a complement – a noun or adjective that follows a linking verb – doesn’t automatically make a verb a linking verb. ” Here, “smells” is a linking verb connecting “soup” to the adjective “delicious,” which describes the soup.
What's more, the “look” verb presents a persistent challenge. Even so, as highlighted in the pitfalls, it’s a versatile word. In real terms, 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 Most people skip this — try not to..
Pulling it all together, mastering linking verbs requires a nuanced understanding of their function and a willingness to analyze sentence structure. 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.
