What Are Adjectives as Subject Complements?
When we talk about adjectives as subject complements, we're referring to adjectives that complete the meaning of the subject by following a linking verb. This is part of a broader grammatical concept called predicate adjectives, which describe the subject directly.
Definition:
An adjective used as a subject complement follows a linking verb and describes or identifies the subject of the sentence.
Key points:
- It renames or describes the subject.
- It is linked to the subject via a linking verb like "is," "seems," "becomes," or "appears."
- It provides essential information about the subject's state or qualities.
Examples:
- The sky is blue.
- She seems tired.
- The flowers are beautiful.
In each case, the adjectives ("blue," "tired," "beautiful") complete the idea of the subject, giving us a full picture of what is being discussed.
The Role and Importance of Adjectives as Subject Complements
Using adjectives as subject complements is vital for creating clear, descriptive sentences. They help in making statements more informative and vivid. Here’s why they matter:
- They clarify the state or condition of the subject.
- Enhance sentence richness by adding detail without complicating syntax.
- Help express opinions, feelings, or perceptions clearly, especially with linking verbs like "seems," "feels," or "looks."
- Play a key role in passive voice and descriptive writing to make communication concise and direct.
Why should you care?
Mastering the use of adjectives as subject complements allows you to write more expressive and precise sentences, whether in essay writing, storytelling, or everyday communication.
Proper Positioning of Adjectives as Subject Complements
Correct placement ensures clarity. Adjectives used as subject complements immediately follow the linking verb, not before or after the subject.
Sentence Structure:
Subject + Linking Verb + Adjective (Subject Complement)
- Examples:
- The cake is delicious.
- The answers seem correct.
- My brother is tall.
Important tips:
- Never place the adjective before the subject.
- Do not confuse subject complements with predicate adjectives that modify a noun within the predicate.
For clarity, avoid misplaced modifiers, which can lead to confusing or awkward sentences.
How to Identify and Use Adjectives as Subject Complements
Step-by-step Approach:
- Find the subject: Who or what is the sentence about?
- Locate the linking verb: Is it "be" (am, is, are), "seems," "becomes," "looks," etc.?
- Check the word following the verb: Does it describe or identify the subject?
- Verify it’s an adjective: Is the word an adjective? (e.g., "happy," "old," "tall")
- Ensure it describes or defines the subject: Does it make sense as a description or identification?
Practice Exercise:
Identify the adjective as subject complement in this sentence:
- The sky looks grey.
Answer: "grey" is an adjective functioning as the subject complement.
Common Mistakes with Adjectives as Subject Complements and How to Avoid Them
| Mistake | Correct Approach | Explanation | Example |
| — | — | — | — |
| Using adjectives before the subject | Place adjectives after linking verb | Adjectives in this function follow the verb, not before | 'The sky is blue,' NOT 'blue sky is' |
| Using an action verb instead of a linking verb | Use "be," "seems," "becomes," etc. | Action verbs don’t suit subject complements | Correct: 'She is happy.' Wrong: 'She runs happy.' |
| Confusing subject complement with predicate adjective | Remember, subject complement renames/defines subject | Focus on the role in sentence | 'The puppy is adorable.' (adjective describes puppy) |
Tip: Always check if the adjective directly describes or identifies the subject and follows a linking verb.

Sometimes, adjectives pair with other words to enhance meaning. Here are some common variations:
