When crafting sentences in English, we often focus on subjects and verbs, but another crucial component that adds depth to our expressions is the predicate nominative. This essential grammatical structure helps us define, identify, and elaborate on the subject of our sentences with precision and clarity.
A Predicate Nominative in Grammar (sometimes called a predicate noun) is a noun or pronoun that follows a linking verb and renames, identifies, or further defines the subject of the sentence. Unlike other sentence components that describe actions, Predicate Nominative in Grammar create a relationship of equivalence with the subject.
Consider this simple example:
Sarah is a doctor
In this sentence, “Sarah” is the subject, “is” serves as the linking verb, and “a doctor” functions as the predicate nominative. The predicate nominative “a doctor” renames and identifies what Sarah is.
The Anatomy of Sentences with Predicate Nominative in Grammar
To fully understand predicate nominatives, we need to examine the basic structure of sentences that contain them:
Subject: The person, place, thing, or idea that the sentence is about
Linking Verb: A verb that connects the subject to information about the subject
Predicate Nominative: The noun or pronoun that renames or identifies the subject
This three-part structure creates a relationship where the predicate nominative gives us additional information about the subject’s identity or nature.
Types of Linking Verbs in Predicate Nominative Constructions
Predicate nominatives always follow linking verbs. These special verbs don’t show action but instead connect the subject with information about it. The most common linking verbs used with predicate nominatives include:
| Linking Verb Category | Examples | Usage with Predicate Nominatives |
|---|---|---|
| Forms of “to be” | am, is, are, was, were, will be, has been | Most common and direct equivalence |
| Sense Verbs | looks, smells, tastes, sounds, feels | Can function as linking verbs when not describing actions |
| State-of-Being Verbs | appears, seems, becomes, remains, grows | Indicate change or continuation of state |
| Status Verbs | continues, stays, turns, proves | Show development or persistence of identity |
When these verbs function as linking verbs, they create the perfect environment for predicate nominatives to rename the subject.
Identifying Predicate Nominatives in Sentences
Being able to recognize predicate nominatives in sentences helps improve both reading comprehension and writing skills. Let’s examine some examples with the predicate nominatives highlighted:
- Simple predicate nominative: “Leonardo DiCaprio is an actor.”
- Compound predicate nominative: “My sister is a doctor and a researcher.”
- Predicate nominative with modifiers: “That building remains the tallest structure in our city.”
- Predicate nominative with a gerund: “Her favorite activity is swimming.”
Each of these examples shows how predicate nominatives function to provide essential information about the subject.
Predicate Nominatives vs. Direct Objects Understanding the Difference
One common source of confusion is distinguishing between predicate nominatives and direct objects. Both follow verbs and are nouns or pronouns, but they serve fundamentally different purposes in sentences:
| Feature | Predicate Nominative | Direct Object |
|---|---|---|
| Verb Type | Follows linking verbs | Follows action verbs |
| Relationship to Subject | Renames or identifies the subject | Receives the action of the verb |
| Question to Identify | What is the subject? | What did the subject do to something? |
| Example | “She became a lawyer.” | “She studied law.” |
| Function | Completes the meaning of the linking verb | Shows what receives the action |
This distinction is crucial for understanding sentence structure and for correct pronoun usage, which we’ll explore in greater detail.
Predicate Nominatives vs. Predicate Adjectives Subtle but Important Distinctions
While predicate nominatives rename or identify the subject, predicate adjectives describe qualities or attributes of the subject. Both follow linking verbs, but they serve different grammatical functions:
| Predicate Nominative | Predicate Adjective |
|---|---|
| Noun or pronoun | Adjective |
| “Marcus is a teacher.” | “Marcus is dedicated.” |
| Identifies what the subject is | Describes how the subject is |
| “The problem became a crisis.” | “The problem became serious.” |
| “This car is a Mercedes.” | “This car is expensive.” |
Understanding this distinction helps writers choose the appropriate structure to convey their intended meaning. Sometimes, changing between a predicate nominative and a predicate adjective can subtly alter the emphasis of a sentence.
Complex Forms of Predicate Nominative in Grammar
Predicate nominatives can appear in various forms beyond simple nouns, adding richness and precision to our language:
Compound Predicate Nominatives
When multiple nouns or pronouns serve as predicate nominatives in the same sentence, we call this a compound predicate nominative:
- “The three finalists were John, Maria, and Peter.”
- “The main ingredients are flour, sugar, and eggs.”
- “She will be our guide, our translator, and our cultural advisor during the trip.”
Gerunds as Predicate Nominatives
A gerund is a verb form ending in “-ing” that functions as a noun. When used as a predicate nominative, it identifies the subject in terms of an activity:
- “Her passion is painting.”
- “The hardest part was convincing the committee.”
- “Their favorite weekend activity is hiking in the mountains.”
Noun Phrases and Clauses as Predicate Nominatives
Sometimes predicate nominatives consist of entire phrases or clauses:
- “My goal is to finish this project by Friday.” (infinitive phrase)
- “The reality is that we need more time.” (noun clause)
- “His suggestion was that we reconsider our approach.” (noun clause)
The Case Conundrum Pronouns as Predicate Nominative in Grammar
One of the most debated topics regarding predicate nominatives involves the correct case for pronouns. According to traditional grammar rules, since predicate nominatives rename the subject, they should use the nominative (subjective) case:
- “It is I.” (nominative case)
- “The winner was she.” (nominative case)
- However, in modern English, especially in spoken language, the objective case has become widely accepted:
- “It is me.” (objective case)
- “The winner was her.” (objective case)
This table compares the traditional rule with contemporary usage:
| Pronoun Form | Traditional Rule | Contemporary Usage | Level of Formality |
|---|---|---|---|
| First Person Singular | “It is I.” | “It is me.” | Formal vs. Casual |
| Third Person Singular (M) | “The best player was he.” | “The best player was him.” | Formal vs. Casual |
| Third Person Singular (F) | “The leader must be she.” | “The leader must be her.” | Formal vs. Casual |
| First Person Plural | “The responsible ones are we.” | “The responsible ones are us.” | Formal vs. Casual |
Navigating the Case Debate
For modern writers and speakers, here are practical guidelines:
- In formal academic writing: Consider using the traditional nominative case.
- In most everyday writing and speaking: The objective case sounds more natural to most English speakers.
- When in doubt: Restructure the sentence to avoid the issue altogether.
For example, instead of choosing between “It was I who completed the project” and “It was me who completed the project,” you could simply write “I completed the project.”
Common Patterns and Structures with Predicate Nominative in Grammar
Predicate nominatives often appear in recognizable sentence patterns:
| Pattern | Structure | Example |
|---|---|---|
| Identity | Subject + to be + what/who it is | “Water is a compound.” |
| Classification | Subject + forms of “to be” + category | “Tigers are mammals.” |
| Role Definition | Person + becomes/remains + role | “She became the CEO.” |
| Equivalence | This + is + that | “This solution is the answer.” |
| Definition | Term + means/signifies + meaning | “Photosynthesis is the process by which plants make food.” |
Using Predicate Nominative in Grammar Effectively in Writing
Predicate nominatives offer writers versatile tools for creating clear, concise, and impactful sentences. Here are some ways to use them effectively:
For Clear Definitions and Explanations
Predicate nominatives excel at providing precise definitions:
- “A metaphor is a figure of speech that makes an implied comparison.”
- “Mitosis is the process of cell division.”
- “Democracy remains the foundation of our political system.”
For Emphatic Identification
When you want to emphasize identity or classification:
- “She is the expert we need for this project.”
- “This document is proof of our agreement.”
- “You are the reason for our success.”
For Sentence Variety
Alternating between predicate nominatives and other sentence structures creates rhythm and maintains reader interest:
“John teaches at the university. He is a professor of linguistics. His research focuses on ancient languages.”
Common Mistakes with Predicate Nominative in Grammar
Being aware of common errors can help improve writing clarity:
| Mistake | Incorrect Example | Corrected Version |
|---|---|---|
| Confusing with direct objects | “I became a doctor” (correct) vs. “I became” (incomplete) | “I became a doctor.” |
| Using adjectives when nouns are needed | “The problem is solved.” (adjective, not a predicate nominative) | “The problem is a difficult puzzle.” |
| Agreement errors | “The main issue are the costs.” | “The main issue is the costs.” |
| Vague nominatives | “The solution is a thing we discussed.” | “The solution is a comprehensive audit.” |
| Overuse in succession | “He is a teacher. She is a doctor. They are neighbors.” | Vary sentence structure for better flow. |
