A participle is a form of a verb used to build verb phrases or describe nouns and pronouns. English has two basic participle forms: the present participle, usually ending in -ing, and the past participle, which may have a regular -ed ending or an irregular form.
Consider these sentences:
- The mechanic is examining the engine.
- The damaged engine needs replacement parts.
- The mechanic has examined the engine.
Examining is a present participle used with is. Damaged is a past participle describing the engine, while examined is a past participle used with has.
The same verb can appear in different grammatical constructions. Its form is one part of the explanation; the surrounding words tell us what it is doing.
Types of Participles in English
English has two basic participle forms: present and past. Grammar lessons also discuss perfect participles, which are constructions formed using having and a past participle.
| Type | Form | Examples |
|---|---|---|
| Present participle | Verb + -ing | preparing, running |
| Past participle | Regular or irregular form | prepared, written |
| Perfect participial construction | having + past participle | having prepared |
| Perfect passive construction | having been + past participle | having been selected |
Perfect participial constructions combine existing participle forms rather than introducing a third simple verb form.
Present Participles
A present participle is the -ing form of a verb.
| Base verb | Present participle |
|---|---|
| investigate | investigating |
| organize | organizing |
| begin | beginning |
| lie | lying |
| travel | traveling / travelling |
Some verbs require spelling changes. Begin doubles its final consonant, lie changes ie to y, and organize drops its final e before adding -ing.
Traveling is standard in American English, while travelling is standard in British English.
Present participles can form part of a verb phrase or describe nouns.
The research team is investigating the unusual readings.
Here, investigating forms part of a progressive verb phrase.
Compare:
The investigating officers requested another interview.
In this sentence, investigating modifies officers.
The form is unchanged, but its function is different.
Past Participles
A past participle is a verb form used in perfect constructions, passive constructions, and certain modifiers.
Regular verbs usually form their past participles with -ed. Irregular verbs follow different patterns.
| Base verb | Simple past | Past participle |
|---|---|---|
| finish | finished | finished |
| write | wrote | written |
| take | took | taken |
| choose | chose | chosen |
| build | built | built |
| go | went | gone |
| run | ran | run |
Some irregular verbs have distinct simple-past and past-participle forms, such as wrote and written. Others, such as built, use the same form for both.
For a wider comparison of regular and irregular verb forms, see English verb forms (V1, V2, V3, V4, and V5).
Present and Past Participles Do Not Indicate Tense
The names present participle and past participle can be misleading.
A present participle does not necessarily describe something happening now. Similarly, a past participle does not automatically refer to an event that happened in the past.
Consider the verb test.
| Sentence | Time reference | Participle |
|---|---|---|
| The engineers are testing the prototype. | Present | testing |
| The engineers were testing the prototype. | Past | testing |
| The engineers will be testing the prototype tomorrow. | Future | testing |
The participle testing stays the same.
The auxiliary verbs and the larger construction establish the time reference.
Past participles work similarly:
The team has completed the inspection.
The team had completed the inspection before noon.
The team will have completed the inspection by Friday.
Completed remains a past participle in all three sentences.
Participles are non-finite verb forms. They do not independently mark tense or agree with a subject in the way a finite verb does.
How Participles Work in Verb Phrases
Participles appear in three important English verb constructions: progressive forms, perfect forms, and passive voice.
Progressive Verb Forms
Progressive constructions use a form of be followed by a present participle.
Structure: be + present participle
The volunteers were sorting donations throughout the afternoon.
Sorting is the present participle. The auxiliary were helps place the activity in the past.
Progressive constructions commonly present an action as ongoing or in progress at a particular time.
Perfect Verb Forms
Perfect constructions use a form of have followed by a past participle.
Structure: have + past participle
The publisher had received the manuscript before the deadline.
Received is the past participle.
The complete verb phrase had received places the receipt of the manuscript before another past point.
Passive Voice
Passive constructions commonly use a form of be followed by a past participle.
Structure: be + past participle
The final proposal was approved by the board.
The proposal receives the action, while the board performs it.
Passive constructions can also use get in some contexts:
The files got deleted during the update.
This is more conversational than a corresponding passive construction with be.
A verb phrase can also contain more than one participle:
The historic theatre is being restored.
Being is a present participle, while restored is a past participle. Together with is, they form a present progressive passive construction.
Participles Used as Adjectives and Modifiers
Participles can describe people, objects, and situations much like ordinary adjectives.
Consider:
The flickering lights made the corridor difficult to navigate.
Flickering describes the lights.
Now compare:
The abandoned warehouse was converted into an art gallery.
Abandoned describes the warehouse.
Both words come from verbs, but here they modify nouns rather than forming the main verb phrase.
-ing and -ed Adjectives
Many pairs of participial adjectives describe different sides of an experience.
Compare:
The documentary was fascinating.
The audience was fascinated.
Fascinating describes something that produces interest. Fascinated describes the audience’s response.
Other pairs work similarly.
| -ing adjective | -ed adjective |
|---|---|
| confusing instructions | confused applicants |
| disappointing results | disappointed supporters |
| exhausting work | exhausted employees |
| alarming news | alarmed residents |
The difference is not present versus past.
Both forms can describe a present situation:
The announcement is surprising.
The staff are surprised.
The intended meaning determines which form is appropriate.
Past Participles Are Not Always Passive
Past participles often have passive meanings, especially when derived from transitive verbs.
For example:
The stolen bicycle was recovered near the station.
Stolen describes a bicycle that someone stole.
But not every past participle has a passive meaning.
Compare:
The fallen leaves covered the garden path.
Fallen describes leaves that have fallen. It does not mean someone performed the action of falling on them.
The verb fall is intransitive here, and the participle describes the resulting condition.
Past Participle or Adjective?
Some participle forms can appear in constructions describing either an event or a state.
Compare:
The door was closed by the caretaker at six.
The door remained closed throughout the afternoon.
The first sentence describes a passive event: the caretaker closed the door.
In the second, closed describes the door’s condition.
The difference is not merely whether the participle follows a form of be. The surrounding construction and context help establish whether the sentence describes an action or a state.
Participles vs. Gerunds and Simple Past Verbs
Different grammatical forms sometimes look identical. The -ing ending and regular -ed ending are especially likely to cause confusion.
Gerund vs. Present Participle
In traditional grammar, a gerund is an -ing form used in a noun-like role. A present participle can help form a verb phrase or introduce a modifying construction.
Compare three uses of reviewing.
| Sentence | Function |
|---|---|
| Reviewing the proposals took three hours. | Gerund phrase functioning as the subject |
| The committee is reviewing the proposals. | Present participle in a progressive verb phrase |
| The committee reviewing the proposals will meet tomorrow. | Present participle introducing a modifier of committee |
The word reviewing is spelled identically in all three sentences.
In the first, reviewing the proposals names an activity and functions as the subject.
In the second, is reviewing forms a progressive verb phrase.
In the third, reviewing the proposals identifies which committee will meet.
Some modern grammars analyze gerunds and present participles together as gerund-participles. The traditional distinction remains useful when explaining their different grammatical functions.
Simple Past vs. Past Participle
A similar confusion occurs with verbs whose simple past and past participle forms are identical.
Compare:
The editor checked the references yesterday.
The editor has checked the references.
In the first sentence, checked is a finite simple-past verb.
In the second, it is a past participle used with has.
The difference is easier to see with some irregular verbs:
The children drank the juice.
The children have drunk the juice.
Drank is the simple past form. Drunk is the past participle.
The grammatical construction, not just the spelling, tells you which form is being used.
Participial Phrases and Clauses
A participle can introduce a group of words that adds information about a noun, an action, or the circumstances of a sentence.
These constructions are commonly called participial phrases or participle clauses, depending on the grammatical framework and the structure involved.
Participial Phrases That Modify Nouns
Consider:
The documents stored in the basement were badly damaged.
Stored in the basement identifies the documents being discussed.
Now compare:
The documents, stored in the basement for decades, were finally digitized.
Here, the phrase adds extra information about documents already identifiable from the context.
The commas mark the information as supplementary rather than essential for identifying the documents.
Reduced Relative Clauses
Some participial phrases can replace longer relative clauses.
Compare:
The researcher who is presenting the findings will answer questions afterward.
The researcher presenting the findings will answer questions afterward.
The second sentence omits who is.
A past participle can be used similarly:
The equipment that was installed last month has already been inspected.
The equipment installed last month has already been inspected.
These shorter versions preserve the intended meaning.
However, not every relative clause can be reduced this way without changing its meaning or making the sentence unnatural.
Participial Clauses That Express Circumstances
Participial clauses can explain what was happening, why something happened, or what resulted from an event.
Consider:
Standing beside the platform, Elena noticed a crack in the station wall.
The participial clause describes what Elena was doing when she noticed the crack.
Now compare:
Recognizing the error, the accountant corrected the figures.
Recognizing the error explains why the accountant made the correction.
An -ing clause can also express a result:
The pipe burst, flooding the storage room.
The flooding resulted from the pipe bursting.
The context establishes whether the added clause describes a simultaneous activity, a reason, or a consequence.
Perfect Participial Clauses and the Order of Events
A perfect participial construction usually contains having followed by a past participle. It commonly makes an earlier completed action or experience explicit.
Compare:
Checking the figures, Rina noticed a missing entry.
The noticing happened while Rina was checking the figures.
Now consider:
Having checked the figures, Rina sent the report to her supervisor.
The checking was completed before she sent the report.
Active and Passive Perfect Clauses
An active perfect participial clause uses:
having + past participle
Having completed the restoration, the team reopened the museum.
The team completed the restoration before reopening the museum.
A passive perfect participial clause uses:
having been + past participle
Having been warned about the storm, the hikers changed their route.
The hikers received the warning before changing their route.
In introductory participial clauses like these, the understood subject normally needs to match the subject of the main clause.
For example, the hikers are the people who received the warning and changed their route.
Is a Perfect Participle Always Necessary?
No. An ordinary -ing clause can sometimes describe events that happen in a natural sequence.
Opening the envelope, Marcus discovered a handwritten note.
The opening logically comes before the discovery.
There is no need to use having opened unless the completed earlier action needs particular emphasis.
Sometimes a full clause is more natural:
After Marcus examined the records, he contacted the supplier.
Participial clauses are useful when they connect events clearly, not simply because they make a sentence shorter.
Dangling and Misplaced Participles
Participial phrases need a clear connection to the person or thing they describe.
If that connection is missing or the phrase appears beside the wrong noun, the sentence may suggest something unintended.
Dangling Participles
Consider:
Walking into the conference room, the presentation had already started.
The opening phrase makes it appear that the presentation was walking into the room.
The intended person is missing.
A clearer version is:
Walking into the conference room, I realized that the presentation had already started.
Now I is clearly the person entering the room.
Another natural correction is:
When I walked into the conference room, the presentation had already started.
Both versions identify who was walking.
Misplaced Participial Phrases
Suppose a journalist is wearing a blue jacket while interviewing a scientist.
This sentence gives the wrong impression:
The journalist interviewed the scientist wearing a blue jacket.
The phrase wearing a blue jacket most naturally describes the scientist.
If the journalist was wearing the jacket, a clearer version is:
Wearing a blue jacket, the journalist interviewed the scientist.
The original sentence would be correct if the scientist were wearing the jacket. The problem is that it does not express the writer’s intended meaning.
When a Full Clause Is Clearer
Consider:
Reviewing the contract, several errors became obvious.
The sentence makes several errors appear to be doing the reviewing.
A clearer version is:
While the lawyer reviewed the contract, several errors became obvious.
The full clause identifies the person performing the action.
A shorter sentence is not necessarily better if its modifier creates confusion.
How to Identify Participles in a Sentence
The same verb can appear in several grammatical constructions. Comparing those uses makes it easier to recognize what a participle is doing.
One Verb, Different Grammatical Functions
Consider the verb write.
| Sentence | Form | Function |
|---|---|---|
| Maya wrote the report yesterday. | wrote | Finite simple-past verb |
| Maya is writing the report. | writing | Present participle in a progressive construction |
| Writing the report took two days. | writing | Gerund phrase functioning as the subject |
| The analyst writing the report called Maya. | writing | Present participle modifying analyst |
| Maya has written the report. | written | Past participle in a perfect construction |
| The report was written overnight. | written | Past participle in a passive construction |
| Having written the report, Maya took a break. | having written | Perfect participial construction |
The -ing form appears in three different functions. The past participle written also appears in more than one construction.
Now consider a sentence containing several participles:
Having received the revised plans, the architect is preparing a proposal for the damaged building.
Having received is a perfect participial construction showing that the plans were received before the main action. Preparing belongs to the progressive verb phrase is preparing. Damaged describes the building.
The auxiliary is establishes the main clause’s present-time reference, while damaged does not specify when the damage happened.
The most reliable way to identify a participle is to read it in the full sentence. Its form tells you what kind of verb form it is, but its grammatical function and surrounding words determine how it is being used.
