Predicate nouns and predicate adjectives are two essential elements of English grammar that play crucial roles in clarifying the meaning of sentences. A predicate noun, also known as a subject complement, renames or identifies the subject of a sentence, while a predicate adjective, sometimes called a subject complement as well, modifies the subject by describing or qualifying it. These grammatical devices work together to provide additional information about the subject, enriching the sentence’s structure and enhancing its comprehensibility.
Understanding Predicate Nouns and Predicates Adjectives
Predicate nouns and predicate adjectives are two essential parts of speech that can add depth and clarity to your writing. Here’s a breakdown of their structures and uses:
Predicate Noun
A predicate noun follows a linking verb and renames or defines the subject of the sentence. It answers the question “Who is/was/will be…?” or “What is/was/will be…?” about the subject.
Structure:
- [Subject] + [Linking Verb] + [Predicate Noun]
Examples:
- The captain of the team is John Smith.
- The dog’s name Muffin.
- The suspect was a thief.
Predicate Adjective
A predicate adjective follows a linking verb and describes a quality of the subject. It answers the question “How is/was/will be…?” about the subject.
Structure:
- [Subject] + [Linking Verb] + [Predicate Adjective]
Examples:
- The sky is blue.
- The soup was delicious.
- The students were excited.
Linking Verbs
Both predicate nouns and predicate adjectives require a linking verb to connect them to the subject. Common linking verbs include:
- Is, am, are
- Was, were
- Will be, would be
Table of Common Linking Verbs
| Verb | Example |
|---|---|
| Is | The car is a BMW. |
| Am | I am a teacher. |
| Are | We are a family. |
| Was | He was the captain. |
| Were | You were right. |
| Will be | She will be a doctor. |
Tips
- Use a predicate noun when the subject is being renamed or defined.
- Use a predicate adjective when the subject is being described.
- Make sure the predicate noun or adjective agrees with the subject in number and gender.
Question 1:
What are the differences between a predicate noun and a predicate adjective?
Answer:
- A predicate noun renames or clarifies the subject of a sentence.
- A predicate adjective describes or modifies the subject of a sentence.
In a Subject-Predicate-Object sentence:
- Subject: The noun or pronoun that performs the action or exists.
- Predicate: The verb that describes the action or state of being.
- Object: The noun or pronoun that receives the action or modifies the predicate.
Question 2:
How can you identify a predicate noun in a sentence?
Answer:
A predicate noun follows a linking verb (also known as a copular verb), such as:
- is, am, are, was, were
- seems, appears, feels, looks
Question 3:
When should you use a predicate adjective instead of a predicate noun?
Answer:
Use a predicate adjective when:
- The attribute of the subject is not a name or title but a quality or characteristic.
- The purpose is to describe or modify the subject, not to rename or clarify it.
