Predicates Meaning
A predicate completes the story of a subject, meaning it completes a sentence.
Predicate: the portion of the sentence that completes the action(s) of a subject. It is any verb, any helping verbs, and any phrases that accomplish this.
The following is an example of a simple sentence with a subject (purple) and predicate (pink).
The robot sings.
Here, “sings” is a single verb. It still qualifies as the predicate of the sentence, though, because it completes the action of the subject.
Because a predicate is defined by its relationship to a subject, it will always be part of a complete sentence.
In the above example, “sings” is an example of a simple predicate. A simple predicate is one of three overarching kinds of predicates.
Fig. 1 - Everything that our robot does is the predicate of its sentence.
Simple Predicates
Unsurprisingly, a simple predicate has few frills attached.
Simple predicate: the main verb and its auxiliary verbs
Main verb: any verb accomplished by the subject
Auxiliary verb: any necessary part of a verb besides the main verb
Understanding the main verb is simple enough. In the following examples, the main verb is highlighted in pink.
The cougar sprints through the field.
The panther waits on a rock.
The tiger leaped toward me.
However, not all verbs are so barren. Take the future continuous tense, which includes the words “will + be.”
I will be flying today.
In this sentence, “flying” is the main verb, of course. However, it can’t stand on its own.
I … flying today.
Doesn’t make any sense, right? This is because, in the future continuous tense, “flying” is part of a compound verb. A compound verb is a verb requiring more than one word. The parts of a compound verb that aren’t the main verb are auxiliary verbs (in green).
I will be flying today.
So, to identify a simple predicate, you simply identify the main verb and any necessary part of that particular verb tense. Sometimes, this will be one word, and sometimes this will be as many as four words, such as the future perfect continuous tense, which not confusingly at all combines “will + have + been” with a present participle (purple).
In thirty minutes, I will have been doing the laundry for an hour!
A simple predicate may fail to complete a sentence (without help): Although a predicate definitively completes a sentence, it might only be part of that task. This is true if the main verb requires an object. Take this example:
The man coaxes
This example contains a subject and a main verb, meaning it contains a subject and a simple predicate, but it’s not a complete sentence because “to coax” is a transitive verb requiring an object (added in purple).
The man coaxes his buddy to give him the money.
A simple predicate does complete a sentence. You won’t find a simple predicate without a complete sentence; however, you can identify it separately for the sake of grammatical study. More will be said on this in the discussion of complete predicates.
The simple predicate is a good place to start with understanding predicates, as it helps you see some verbs require extra words to work. However, there is more to the story: the compound predicate and the complete predicate.
Three Types of Predicates
There are three types of predicates in all, although they are not mutually exclusive: the simple predicate, the compound predicate, and the complete predicate. Each is merely a way of classifying all or part of a sentence’s predicate.
Complete Predicate
A complete predicate is, for all intents and purposes, the predicate. A complete predicate completes the action(s) of a subject. It is any verb, any helping verbs, and any phrases that accomplish this. The complete predicate is highlighted here in pink.
Janette had been running for ages.
In this sentence, the complete predicate (and the predicate) contains the main verb “running,” the auxiliary verbs “had been,” and the prepositional phrase “for ages.”
Here are some more examples, with the predicate (and complete predicate) highlighted in pink:
The microphone flew from Daltrey’s hand.
Pete’s guitar broke as it smashed into the stage.
The Ox continued to play unfazed.
Moon the Loon laughed madly.
In each highlighted instance, the complete predicate is also the predicate. So, what gives? Why are the predicate and complete predicate the same?
Fig. 2 - How can the same thing said about a guitar be classified as two distinct things?
Here's the answer.
The complete predicate is merely a way of describing a predicate in contrast to the simple predicate. A simple predicate contains the most vital parts of a predicate, while you can say the complete predicate contains all parts of a predicate. This distinction exists as a result of grammatical study, as the simple predicate is more fundamental to the existence of a predicate than any larger construction, so it’s worth identifying on its own.
Consider this. You know that a simple predicate might not function without an object or whatnot. However, a complete predicate never functions without a simple predicate. Take a look again at our examples of complete predicates. Do you notice something? They all have simple predicates within them (highlighted purple).
The microphone flew from Daltrey’s hand.
Pete’s guitar broke as it smashed into the stage.
The Ox continued to play unfazed.
Moon the Loon laughed madly.
When studying anything, you want to break things down to a fundamental level to understand them. Thus a grammarian can identify a predicate, a simple predicate, a complete predicate, and even say when they’re all the same. In the following example, the pink highlighted verb is a simple predicate, a complete predicate, and, well, the predicate!
The band plays.
There is one final classification to consider in the realm of predicates, the compound predicate.
Compound Predicate
A compound predicate contains more than one main verb accomplished by the subject. Here’s what that looks like using only simple predicates.
Abele swims and sprints.
Here, “and” is a coordinating conjunction linking two main verbs within the predicate. Yes, a predicate can contain two or more main verbs! Here’s a compound predicate that contains more than simple predicates.
Abele swims in the lake, sprints overland, and hikes through the hills.
Like the simple predicate, a compound predicate is always a complete predicate. The compound predicate is worth distinguishing because it multiplies the vital main verb — a procedure with its own grammatical rules. Compounds are a vital part of English grammar, from compound subjects to compound predicates. You will find the use of coordinating conjunctions in all compound constructions.
Subjects and Predicates
When identifying subjects and predicates, there are three things to identify in actuality: the subject(s), the predicate(s), and the clauses and phrases that aren’t either one!
Above, it’s been stated that a predicate completes a sentence. This is true in simple sentences, which contain only an independent clause. However, more precisely, a predicate is what completes an independent clause, which can be combined with dependent clauses and phrases to create compound, complex, and compound-complex sentences.
Sentence Type | Construction | Example |
Simple | Independent clause | Jack ran toward me. |
Compound | 2+ independent clauses | Jack ran toward me and bit me. |
Complex | Independent clause + dependent clause(s) or phrase(s) | Angry with me, Jack ran toward me. |
Compound-complex | 2+ independent clauses + dependent clause(s) or phrase(s) | Angry with me, Jack ran toward me and bit me. |
Everywhere you read “independent clause” above contains a subject + predicate, which defines an independent clause. However, complex sentences contain things that aren’t independent clauses, including dependent clauses and types of phrases.
An independent clause (subject + predicate) is the core of any complete sentence, but it can contain more than that, which is the “third thing” you need to identify: clauses and phrases that aren’t the independent clause.
This is easier than it sounds. Look for the comma! If something is set aside by a comma, isn't part of a compound construction, and can’t stand on its own as a complete sentence (in other words, it can’t be an independent clause), then it is a dependent clause or some kind of phrase, meaning it contains no predicate. Predicates only exist in independent clauses!
Take this example again.
Angry with me, Jack ran toward me.
Here, “angry with me” is an adjective phrase. It cannot stand on its own, so it’s not the subject or predicate of the sentence. “Jack” is the subject because “angry with me” modifies it and because Jack accomplishes the main verb “ran.”
Here are some examples with a subject (purple), a predicate (pink), and clauses or phrases that aren’t either (green).
As the man stopped, his eyes rolled back in his head.
The folks, which were once kind, no longer paid us any mind.
The train, all shrouded in fog, stopped, although my heart continued to race.
Predicate Adjectives
A predicate adjective is an adjective that receives the action of the main verb. In other words, it’s the adjectival object of the main verb. Here’s a simple example:
The child is happy.
Here, “is” is the main verb, while “happy” is the predicate adjective. Here’s another predicate adjective (in pink).
Do we know kindness?
Here, “know” is the main verb, while “kindness” is the predicate adjective, being the object of “know.”
Predicates - Key Takeaways
- A predicate completes the action(s) of a subject. It is any verb, any helping verbs, and any phrases that accomplish this.

Frequently Asked Questions about Predicates
What are predicates?
A predicate completes the action(s) of a subject. It is any verb, any helping verbs, and any phrases that accomplish this.
What is an example of a predicate?
In the following sentence, the bolded portion is the predicate, as it completes the action of the subject: "Pete’s guitar broke as it smashed into the stage."
What is an example of a simple predicate?
A simple predicate is the main verb and its auxiliary verbs. In the following sentence, the bolded portion is a simple predicate: "The band continues to play."
What is the difference between a predicate and a verb?
A predicate contains the main verb of an independent clause. However, verbs can exist in many forms in clauses and phrases that don't contain predicates, such as dependent clauses.
How do you find the predicate?
Break the sentence down into three areas: the subject(s), the predicate(s), and the clauses and phrases that aren’t either one! Remember, a predicate completes the action(s) of a subject. It is any verb, any helping verbs, and any phrases that accomplish this. In the sentence, "As the man stopped, his eyes rolled back in his head," the predicate is "eyes rolled back in his head."
