You're staring at a sentence diagram in seventh grade English. The teacher draws a line down the middle. Subject on the left. Now, predicate on the right. You nod along. Then you get home and realize — you still can't explain what a predicate actually is, let alone give a clean example of a predicate without guessing.
Turns out, most people can't. Even writers who use them perfectly every day.
What Is a Predicate
The predicate is the part of a sentence that tells you what the subject does* or is. That's the short version. In practice, the subject names who or what the sentence is about. The predicate delivers the rest — the action, the state, the description, the whole point of the sentence existing.
Every complete sentence has one. No exceptions.
The Two Pieces You Actually Need to Know
Grammarians split predicates into two flavors: simple predicate and complete predicate.
The simple predicate is just the verb (or verb phrase). Nothing else. And in "The dog barked," the simple predicate is barked*. In "She has been waiting," it's has been waiting*.
The complete predicate? In real terms, that's the verb plus* everything that hangs on it — objects, modifiers, prepositional phrases, the works. In "The dog barked at the mailman," the complete predicate is barked at the mailman*.
Same verb. Different scope. Both are predicates. Both count.
A Quick Example of a Predicate in the Wild
Take this sentence: My neighbor's cat knocked over the vase.*
Subject: My neighbor's cat*
Simple predicate: knocked*
Complete predicate: knocked over the vase*
That's it. That's an example of a predicate doing its job.
Why It Matters / Why People Care
You might wonder — why does anyone outside a linguistics department care about this?
Because predicates are where meaning lives.
The subject sets the stage. The predicate is the play. If you can't identify the predicate, you can't reliably:
- Fix run-on sentences
- Spot fragments
- Vary your sentence structure
- Understand why a sentence feels "off" even when the grammar checks out
I've edited hundreds of articles where the writer had solid vocabulary but shaky predicate control. They'd stack three predicates onto one subject without realizing it. Or they'd bury the main verb under so many modifiers the reader forgot the subject by the time they reached it.
That's not a style issue. That's a predicate issue.
Real-World Consequences
In legal writing, a misplaced predicate can change liability. In technical docs, it can make a procedure unreadable. In fiction, it can kill pacing.
Here's a sentence from a real government form I once rewrote:
The applicant must submit the completed application along with all required documentation to the designated office prior to the deadline.*
The predicate is must submit the completed application along with all required documentation to the designated office prior to the deadline*. Technically correct. Practically a wall of text.
Break the predicate. Shorten it. Submit the completed application and required documents to the designated office before the deadline.
Same meaning. Half the cognitive load.
How It Works (or How to Do It)
Predicates aren't one-size-fits-all. Even so, they shift shape depending on the verb type, the sentence structure, and what you're trying to communicate. Let's walk through the main categories — each with a clear example of a predicate in action.
Action Predicates (Transitive and Intransitive)
Most predicates are built around action verbs. The distinction that matters: does the action transfer to an object?
Transitive — the verb takes a direct object.
She threw the ball.*
Predicate: threw the ball*
Simple predicate: threw*
Intransitive — no object needed.
He slept.*
Predicate: slept*
That's the whole thing.
Some verbs swing both ways. Run is intransitive in "She runs every morning" but transitive in "She runs a marathon" (meaning: she organizes/manages it). The predicate shifts accordingly.
Linking Predicates (State-of-Being)
These don't show action. They connect the subject to a complement — a noun, pronoun, or adjective that renames or describes it.
Common linking verbs: be, seem, become, appear, feel, look, smell, sound, taste, grow, turn, stay, remain.*
-
The soup tastes salty.*
Predicate: tastes salty*
Simple predicate: tastes*
Salty* is a subject complement (predicate adjective). -
He became a doctor.*
Predicate: became a doctor*
A doctor* is a subject complement (predicate nominative).
Here's where people trip up: they want to use an adverb after a linking verb. Consider this: he feels badly. * No. He feels bad.* The predicate adjective modifies the subject, not the verb.
Compound Predicates
One subject. Two or more verbs. That's a compound predicate.
-
The engine sputtered and died.*
Compound simple predicate: sputtered and died* -
She opened the door, walked in, and sat down.*
Three verbs. One subject. One compound predicate.
This is a powerful tool for pacing. He walked out. Plus, three short sentences. * One compound predicate. On top of that, or combine them: He walked out, lit a cigarette, and watched the smoke rise. On top of that, * Three simple predicates. He lit a cigarette. He watched the smoke rise.Hemingway used it constantly. Different rhythm.
This part deserves a bit more attention than it usually gets.
Predicates in Different Sentence Types
The predicate doesn't change its nature — but its position and punctuation do.

Declarative: The meeting starts at noon.* (Predicate follows subject)
Interrogative: Does the meeting start at noon?* (Auxiliary verb does* fronts the predicate; main verb start* stays put)
Imperative: Start the meeting.* (Subject you is implied. Predicate is the whole sentence.)
Exclamatory: What a meeting that was!* (Predicate: was — hiding inside a wh-cleft structure)
Predicates with Modifiers and Complements
This is where predicates get long — and where writers lose control.
- The committee reluctantly approved the revised budget after hours of debate.*
Complete predicate: reluctantly approved the revised budget after hours of debate*
Simple predicate: approved*
Every word after approved* modifies or completes it. Consider this: adverb (reluctantly*). Think about it: direct object (the revised budget*). Prepositional phrase (after hours of debate*). All part of the predicate.
You can stack these. Sometimes that's deliberate. But each addition makes the sentence heavier. Often it's accidental.
Predicate Nominatives vs. Predicate Adjectives
Worth a closer look, because this distinction shows up on standardized tests and in style guides.
Predicate nominative — a noun or pronoun that renames the subject.
- The winner is she.* (Formal)
- The winner is her.* (Common, accepted in informal use)
- My brother became a pilot.*
Predicate adjective — an adjective that describes the subject.
- The room feels cold.*
- She looks tired.*
- The music grew louder.*
Both follow linking verbs. Both are subject
Both follow linking verbs. Think about it: both are subject to the same rules of agreement and usage, but they function differently in a sentence. In real terms, a predicate nominative renames or identifies the subject, while a predicate adjective describes it. Understanding this distinction helps you choose the right word and avoid the kind of slip‑up that makes editors raise an eyebrow.
How to tell which you need
-
Ask “What noun or pronoun is being identified?”
Example:* The CEO proved to be him.*
Here him renames the subject the CEO, so it’s a predicate nominative. If you replaced it with an adjective, the sentence would lose meaning: The CEO proved to be * (no adjective fits). -
Ask “What quality or state is being described?”
Example:* The presentation felt boring.*
Boring supplies a descriptive quality, making it a predicate adjective. Substituting a noun would change the sentence’s intent: The presentation felt boringness (awkward) versus The presentation felt boring* (natural).
Case agreement matters
-
Predicate nominative should match the subject in case. In formal writing, the subject’s case is preferred, even if it looks “wrong” to the ear.
Correct (formal):* She is the president.*
Acceptable (informal):* She is president.* -
Predicate adjective never changes case because adjectives are invariant.
Common pitfalls
-
Confusing with direct objects: A verb can take both a direct object and a predicate nominative or adjective, but the placement of the word determines its role.
Misread:* They elected John as chair.*
Here John is the direct object of elected*, while chair is a predicate nominative (identifying the object). If you wrote They elected John as chairperson,* chairperson still renames John, not the subject. -
Using the wrong case after “to be”: Many writers write It is her.* because they hear the informal version daily. In a formal essay, keep the nominative: It is she.*
Quick test for writers
- Remove the linking verb (be, seem*, appear*, feel*, etc.) and see what remains.
- If a noun or pronoun stands alone, it’s likely a predicate nominative.
- If an adjective remains, it’s a predicate adjective.
Example:* The weather turned cold.In practice, * → Remove turned*: The weather cold. * The adjective cold describes the subject, confirming a predicate adjective.
When to bend the rules
Style guides differ on informal usage. In dialogue, creative writing, or everyday communication, the objective case after a linking verb is widely accepted. She seems friendly.* (adjective) – fine. Day to day, he called them the winners. * (predicate nominative) – fine. The key is consistency: if you opt for colloquialism, keep it throughout the piece.
Bottom line
Predicate nominatives and predicate adjectives are two sides of the same coin—both follow linking verbs and modify the subject, but one renames it, the other describes it. Mastering the distinction sharpens your prose, prevents awkward constructions, and prepares you for the grammar questions that appear on standardized tests and in professional editing sessions. Keep the test in mind, vary your sentence structures, and let the right word do the work it was meant to do.
