A simple predicate is the main verb of a clause, together with any helping verbs that belong to it. It expresses an action, event, or state without including objects, complements, or ordinary modifiers.
Consider:
The bakery has reopened after several months of renovations.
The simple predicate is has reopened. The helping verb has works with the main verb reopened. The phrase after several months of renovations tells us when the bakery reopened, but it isn’t part of the simple predicate.
A simple predicate may contain one word or several. What matters is which verbs form the main verb phrase of the clause.
Main Verbs and Helping Verbs in Simple Predicates
Some simple predicates consist of a single main verb. Others include helping verbs that express meanings such as possibility, completion, or passive voice.
When the Simple Predicate Is One Word
The old wooden gate creaked in the wind.
The simple predicate is creaked. The phrase in the wind adds information about the event but isn’t included.
A linking verb can also serve as a simple predicate:
The footpath seems unsafe.
Here, seems is the simple predicate. The adjective unsafe describes the footpath through the linking verb, but it isn’t part of the simple predicate.
When Helping Verbs Are Included
Helping verbs, also called auxiliary verbs, work with a main verb.
The repair crew might have overlooked the leak.
The simple predicate is might have overlooked.
Overlooked is the main verb. Might expresses possibility, while have helps form the perfect construction.
Although the simple predicate contains three words, it has only one main verb. Several auxiliaries working with one main verb do not make a compound predicate.
When Have, Be, and Do Are Main Verbs or Helping Verbs
The verbs have, be, and do can function as main verbs or auxiliaries. Their role depends on how they’re used.
| Main-verb use | Auxiliary use |
|---|---|
| Olivia has a spare key. | Olivia has misplaced her key. |
| The upstairs rooms are empty. | The guests are leaving. |
| Marcus did the repairs. | Marcus did finish the repairs. |
In the first column, has, are, and did are main verbs. Each is the simple predicate of its clause.
In the second, has misplaced, are leaving, and did finish contain helping verbs.
The auxiliary did in did finish adds emphasis. It doesn’t describe a second action.
Simple Predicate vs. Complete Predicate
The simple predicate contains the main verb and its helping verbs. The complete predicate includes those verbs and the other elements belonging to the predicate.
The plumber has replaced the damaged pipe under the sink.
- Simple predicate: has replaced
- Complete predicate: has replaced the damaged pipe under the sink
The object the damaged pipe and the phrase under the sink, which describes the pipe, belong to the complete predicate.
The distinction also applies to linking verbs:
The entrance hall felt unusually cold.
Felt is the simple predicate, while felt unusually cold is the complete predicate.
Unusually cold describes the entrance hall. It completes the intended meaning of the linking verb but isn’t included in the simple predicate.
How to Identify the Simple Predicate
The first thing to look for is the main verb of the clause you’re examining. If it has helping verbs, include them.
The difficulty is that other words may appear between those verbs, and a sentence may contain additional verb forms that don’t belong to the main simple predicate.
Helping Verb or Infinitive Clause?
Compare:
The tenants will move before December.
The tenants agreed to move before December.
In the first sentence, will move is the simple predicate. Will is a modal helping verb, and move is the main verb.
In the second sentence, agreed is the simple predicate of the main clause.
To move before December is an infinitive clause completing the meaning of agreed. The verb move belongs to that clause, not to a verb phrase formed with agreed.
Both sentences contain more than one verb form, but only the first has a helping verb working directly with the main verb.
When Other Words Appear Between the Verbs
Consider:
The replacement parts have not yet arrived.
The simple predicate is have arrived.
Not expresses negation, while yet adds information about time. Neither is included in the simple predicate under the usual classroom definition.
The two verbs still work together, even though they aren’t next to each other.
The same principle applies to ordinary adverbs:
The hikers had already reached the shelter.
Had reached is the simple predicate. Already adds time-related meaning but isn’t included.
When a Sentence Contains Several Verb Forms
Consider:
The parcel labelled for Helena might already have been redirected.
There are several words here that look like verbs, but they don’t all belong to the main simple predicate.
The complete subject is the parcel labelled for Helena. Within it, labelled for Helena describes the parcel.
The main clause’s simple predicate is might have been redirected.
It contains the main verb redirected and three helping verbs: might, have, and been.
Already is an adverb placed between the helping verbs. It isn’t part of the simple predicate under the classroom definition used here.
Compare the sentence without the subject modifier and adverb:
The parcel might have been redirected.
The same main verb phrase remains.
This comparison brings together three useful distinctions: a participle can modify the subject, helping verbs can form a longer simple predicate, and an adverb can appear within that verb sequence without becoming part of it.
Simple Predicates in Different Sentence Forms
A simple predicate can appear in statements, questions, commands, and exclamatory clauses.
| Sentence form | Example | Simple predicate |
|---|---|---|
| Statement | The overnight ferry arrived before dawn. | arrived |
| Question | Have the guests arrived yet? | have arrived |
| Command | Please store the boxes upstairs. | store |
| Exclamation | How quickly the weather has changed! | has changed |
In the question, have appears before the subject the guests, while arrived follows it. Both belong to the simple predicate.
In the command, the subject you is understood. Store is the simple predicate, while please adds politeness.
An exclamation isn’t always a complete clause. What a surprise!, for example, has no expressed verb and therefore no simple predicate to identify in the usual way.
Can a Sentence Have More Than One Simple Predicate?
Yes. A sentence can contain multiple main verbs, either coordinated within a compound predicate or belonging to separate clauses.
When Two Main Verbs Share a Subject
The gardener pruned the shrubs and watered the seedlings.
Pruned and watered are coordinated main verbs sharing the subject the gardener.
Together, they form a compound predicate.
In traditional classroom grammar, the individual verbs may also be described as simple predicates within that compound construction.
This is different from might have overlooked, where several verb words form one verb phrase with a single main verb.
When Different Clauses Have Their Own Predicates
When the bell rang, the audience settled into their seats.
This sentence contains two clauses.
In the dependent clause when the bell rang, the subject is the bell and the simple predicate is rang.
In the main clause the audience settled into their seats, the subject is the audience and the simple predicate is settled.
There are two clause-level simple predicates because there are two separate subject–verb relationships.
The number of verbs in a sentence doesn’t tell you everything about its predicates. You also need to know whether those verbs form one verb phrase, share a subject through coordination, or belong to different clauses.
