A participle is a verb form that can describe a noun like an adjective or combine with an auxiliary verb to form a verb phrase. A present participle ends in -ing, while a past participle usually ends in -ed for regular verbs or takes an irregular form such as written or gone.
Key Facts at a Glance
- A present participle always ends in -ing, as in running, singing, and being.
- A regular past participle usually ends in -ed, as in walked, cleaned, and decided.
- A participle does not express tense by itself; auxiliary verbs usually carry tense.
- Present participles commonly form progressive constructions, such as is working.
- Past participles commonly form perfect constructions, such as has worked, and passive constructions, such as was repaired.
- A participle can modify a noun, but an -ing word functioning as a noun is a gerund.
What Is a Participle?
A participle is a nonfinite verb form with two major jobs: it can modify a noun, or it can join an auxiliary verb in a larger verb phrase. The word nonfinite means that the participle does not independently show person, number, or complete tense.
In The dog barking outside belongs to Maya, barking describes the dog. In The dog is barking outside, barking combines with is to form the present progressive verb phrase. The same form appears in both sentences, but its grammatical role changes.
Traditional grammar often calls participles verbal adjectives because participles retain some verb properties while modifying nouns. For example, the carefully painted mural contains painted, which describes mural, while carefully modifies the action of painting.
A participle can also retain an object or modifier:
- the student carrying three books
- the report written by the auditor
- the child laughing loudly
- the machine damaged during shipping
The participle remains connected to the verb from which it comes. That connection explains why participial phrases can contain objects, adverbs, and prepositional phrases.
How Do Present and Past Participles Differ?
Present participles use the -ing form, while past participles use the verb’s third principal form. The most reliable distinction is grammatical form and construction, not a simple active-versus-passive rule.
| Feature | Present participle | Past participle |
|---|---|---|
| Basic form | verb + -ing | regular -ed or irregular third form |
| Examples | walking, breaking, seeing | walked, broken, seen |
| Progressive construction | is walking | not used for this function |
| Perfect construction | not used alone | has walked, has broken |
| Passive construction | not normally used alone | was broken, is seen |
| Adjective example | the breaking wave | the broken window |
| Typical viewpoint | action in progress or active relation | completed result, state, or received action |
The common classroom shortcut says that present participles are active and past participles are passive. That shortcut works for pairs such as the child frightening the dog and the child frightened by the dog, but it is not universally accurate.
In a retired teacher, retired describes a person’s state, not necessarily an action currently received. In a fallen leaf, fallen is not passive because the leaf did not receive an action from an outside agent. Conversely, the remaining tickets uses an -ing form to describe a state rather than an action actively performed by the tickets.
What Is the Main Difference in One Sentence?
A present participle usually presents an activity or developing condition with -ing, whereas a past participle usually presents a completed result, state, or verb form used in perfect and passive constructions.
What Is a Present Participle?
A present participle is the -ing form of a verb used as part of a verb phrase or as a modifier. Examples include working, swimming, driving, being, and having.
| Base verb | Present participle | Modifier example | Verb-phrase example |
|---|---|---|---|
| talk | talking | the talking speaker | is talking |
| run | running | the running water | was running |
| make | making | a making process | is making |
| lie | lying | the lying dog | was lying |
| be | being | a being problem | has been being |
As a verb form, the present participle normally needs an auxiliary:
- She is studying.
- They were waiting.
- I have been working.
The auxiliary determines tense and agreement. In She was studying, was carries past tense, while studying identifies the progressive aspect. Calling studying a “present tense verb” is therefore imprecise.
As an adjective, the present participle can appear before a noun, after a linking verb, or inside a longer phrase:
- the glowing screen
- The screen looks glowing is unnatural in many contexts, but The screen is glowing is a verb phrase.
- The screen glowing in the dark attracted attention
The form is identical, but syntactic function determines the analysis.
What Is a Past Participle?
A past participle is the form used with have in perfect constructions and with forms of be in many passive constructions. Past participles also modify nouns, as in a closed door, a written agreement, and a frozen lake.
| Base verb | Past tense | Past participle | Perfect example |
|---|---|---|---|
| walk | walked | walked | has walked |
| write | wrote | written | has written |
| break | broke | broken | has broken |
| choose | chose | chosen | has chosen |
| take | took | taken | has taken |
| see | saw | seen | has seen |
Regular past participles generally end in -ed, but irregular verbs must be learned individually. The forms went and gone illustrate the difference: went is simple past, while gone is the past participle.
Past participles appear in three especially important structures:
- Perfect aspect: She has finished the report.
- Passive voice: The report was finished yesterday.
- Adjectival use: The finished report is on the desk.
A past participle is not automatically passive. She has finished is active because she performs the action. The form finished is a past participle, but the construction is perfect active voice.
How Are Present and Past Participles Formed?
Present participles are formed by adding -ing, with spelling changes for certain verb endings. Past participles use -ed for regular verbs, while irregular forms require memorization or a reliable dictionary.
| Spelling situation | Present participle | Past participle |
|---|---|---|
| Most verbs | work → working | work → worked |
| Final silent e | make → making | love → loved |
| Short stressed CVC verb | run → running | stop → stopped |
| Final ie | lie → lying | lie → lain |
| Final consonant plus y | study → studying | study → studied |
| Irregular verb | go → going | go → gone |
Present-Participle Spelling Rules
For most verbs, add -ing:
- read → reading
- help → helping
- open → opening
Drop a final silent e:
- write → writing
- dance → dancing
- close → closing
Keep the e in some verbs ending in ee, oe, or ye:
- see → seeing
- agree → agreeing
- dye → dyeing
Double the final consonant in many short verbs with a stressed consonant-vowel-consonant pattern:
- run → running
- sit → sitting
- admit → admitting
British and American spelling conventions differ in some cases. British English commonly writes travelling and cancelled, while American English generally writes traveling and canceled.
Past-Participle Formation
Regular verbs usually add -ed:
- clean → cleaned
- jump → jumped
- ask → asked
A verb ending in silent e adds -d:
- bake → baked
- save → saved
- use → used
A consonant plus y changes y to i:
- carry → carried
- study → studied
- try → tried
Irregular verbs do not follow one universal rule. Their past participles include eaten, driven, known, made, spoken, and understood.
Which Form Should You Use?
Choose a present participle when the sentence needs an -ing form for an ongoing verb phrase or an active, developing description. Choose a past participle when the sentence needs the third verb form for a perfect or passive construction, or when the noun has a completed or resulting state.
| Intended meaning | Correct form | Example |
|---|---|---|
| Ongoing action | present participle | The engineers are testing the bridge. |
| Completed action with have | past participle | The engineers have tested the bridge. |
| Received action | past participle | The bridge was tested by engineers. |
| Active noun modifier | present participle | The engineers testing the bridge wore helmets. |
| Resulting state | past participle | The tested bridge opened safely. |
The noun’s relationship to the action helps, but the auxiliary and sentence structure provide stronger evidence. Compare the boiling water, where the water is undergoing a change, with the boiled water, where boiling has already produced a result.
Present Participles as Adjectives
Present participles often describe something that causes an effect or performs an activity:
- an interesting lecture
- a growing business
- a moving target
- a confusing instruction
The adjective interesting describes a lecture that causes interest. The adjective interested describes a person who experiences interest.
Past Participles as Adjectives
Past participles often describe a condition or result:
- a locked gate
- a damaged package
- a trained technician
- a known problem
The adjective may have an implied agent, but the agent is not always present or relevant. A broken cup may have been broken by a person, an animal, or an accident.
Are All -ing Words Present Participles?
No. An -ing word is a present participle when it functions as a verb form or adjective, but it is a gerund when it functions as a noun.
| Sentence | Function of -ing word | Diagnostic |
|---|---|---|
| Running improves fitness. | Gerund | The activity is the subject. |
| The running athlete waved. | Present participle | The word describes athlete. |
| She is running daily. | Present participle | The word follows progressive auxiliary is. |
| I enjoy running. | Gerund | The activity is the object of enjoy. |
| The water is running. | Present participle | The form completes a verb phrase. |
A practical test is to ask whether the -ing form names an activity or describes a noun. In Swimming is difficult, swimming names an activity and functions as a noun. In the swimming child, swimming modifies child and functions as a participle.
The test is useful but not perfect because English categories can overlap in complex noun phrases. Syntactic position remains the best diagnostic.
Why Are Exciting and Excited Different?
-ing adjectives commonly describe the cause of an emotion, while -ed adjectives commonly describe the person or thing experiencing that emotion. Therefore, a film can be exciting, while its audience is excited.
| Cause | Experiencer | Example |
|---|---|---|
| exciting | excited | The exciting match left fans excited. |
| boring | bored | The boring lecture made students bored. |
| tiring | tired | The tiring hike left us tired. |
| confusing | confused | The confusing map confused visitors. |
| frightening | frightened | The frightening noise frightened the child. |
This pattern applies strongly to emotion adjectives derived from participles, but context still matters. A retired worker is not an emotional experiencer, and a talented musician is not literally someone who has been “talented” by an outside agent.
A useful editing question is: “Does the noun cause the reaction, or does the noun experience it?” The answer usually determines -ing or -ed.
What Are Participial Phrases?
A participial phrase contains a participle plus related words that function together as a modifier. The phrase must attach clearly to the noun it describes.
- Carrying a heavy suitcase, Lina climbed the stairs.
- The technician repairing the printer works on the second floor.
- Exhausted after the overnight flight, Marcus went straight to bed.
- The files stored on the external drive were recovered.
An introductory present-participial phrase often corresponds to a full clause:
- Opening the window, Priya cooled the room.
- After Priya opened the window, she cooled the room.
A past-participial phrase often compresses a passive clause:
- Designed by a local architect, the house received an award.
- Because the house was designed by a local architect, it received an award.
The compressed version saves words, but it also removes explicit information about time, cause, and agency. Use a full clause when the relationship could be interpreted in more than one way.
How Do You Fix a Dangling Participial Phrase?
A dangling participle occurs when the introductory phrase appears to modify the wrong noun. Place the actual doer immediately after the comma, or rewrite the sentence with an explicit subject.
- Incorrect: Walking through the park, the statues seemed enormous.
- Correct: Walking through the park, I thought the statues seemed enormous.
- Correct: As I walked through the park, the statues seemed enormous.
The statues cannot perform walking, so the original modifier dangles. Editors should check both logical agency and grammatical attachment, because a phrase can be near a noun yet still assign an impossible action.
| Problem | Faulty sentence | Reliable repair |
|---|---|---|
| Wrong actor | Driving to work, the rain intensified. | Driving to work, I noticed the rain intensify. |
| Ambiguous actor | Covered in paint, Sam moved the chair. | Sam moved the chair, which was covered in paint. |
| Missing subject | After reviewing the data, several errors appeared. | After reviewing the data, the analyst found several errors. |
| Passive ambiguity | Built in 1890, people visit the house. | Built in 1890, the house attracts many visitors. |
What Are Perfect Participles?
A perfect participle uses having + past participle to show that one action happened before the main action. A passive perfect participle uses having been + past participle when the earlier action was received by the subject.
- Having finished the inspection, the engineer signed the form.
- Having forgotten her key, Dana called the landlord.
- Having been warned about the ice, the hikers slowed down.
The perfect participle emphasizes sequence, but it does not automatically specify an exact time interval. Having eaten, he left indicates that eating preceded leaving; it does not say whether he left one minute or two hours later.
Perfect participles are useful in formal writing, reports, and compressed narratives. They can sound stiff when several appear in conversational dialogue, where after, because, or when may produce clearer prose.
How Do Passive and Perfect Constructions Differ?
The auxiliary determines the construction:
| Construction | Formula | Example | Meaning |
|---|---|---|---|
| Progressive | be + present participle | is working | action in progress |
| Perfect | have + past participle | has worked | action completed or relevant |
| Passive | be + past participle | was examined | subject receives action |
| Perfect passive | have + been + past participle | has been examined | completed received action |
| Perfect participle | having + past participle | having examined | earlier active action |
| Passive perfect participle | having been + past participle | having been examined | earlier received action |
Which Irregular Past Participles Matter Most?
The most useful irregular past participles are the forms that frequently follow have, has, had, or passive forms of be. Learners should memorize the base, simple past, and past participle together rather than memorizing the participle in isolation.
| Base | Simple past | Past participle | Example |
|---|---|---|---|
| go | went | gone | has gone |
| do | did | done | has done |
| eat | ate | eaten | has eaten |
| write | wrote | written | has written |
| take | took | taken | has taken |
| give | gave | given | has given |
| speak | spoke | spoken | has spoken |
| drive | drove | driven | has driven |
| see | saw | seen | has seen |
| choose | chose | chosen | has chosen |
A frequent error is using the simple past after have: She has went is incorrect because has requires the past participle gone. The correct sentence is She has gone to the store.
Common Errors With Participles
Using a Past Participle After “Did”
After did, use the base form, not the past participle:
- Incorrect: Did you written the email?
- Correct: Did you write the email?
The auxiliary did already carries past tense. Adding written creates an incorrect combination.
Using the Simple Past After “Have”
After have, has, or had, use the past participle:
- Incorrect: They have ate lunch.
- Correct: They have eaten lunch.
The perfect auxiliary requires the third principal form.
Treating Every Past Participle as Passive
Has repaired is active in The mechanic has repaired the car. The mechanic performs the action, even though repaired is a past participle.
Confusing a Participle With a Finite Verb
A finite verb can operate as the main verb and show tense or agreement:
- She walks to work.
- They walk to work.
A participle normally needs an auxiliary or another grammatical role:
- She is walking to work.
- the woman walking to work
Overcompressing Important Relationships
Participial phrases can hide the subject, time, cause, or condition. Having reviewed the proposal, approval followed is unclear because approval did not review anything. A full clause, After the committee reviewed the proposal, approval followed, identifies the actor and sequence.
How Can You Identify a Participle in a Sentence?
Use a four-step test: locate the verb-derived form, inspect its ending or irregular form, identify whether an auxiliary precedes it, and determine whether it modifies a noun or functions as a noun.
- Find a possible verb form such as running, broken, or written.
- Ask whether it follows be in a progressive or passive construction.
- Ask whether it follows have in a perfect construction.
- If it modifies a noun, identify the noun it describes.
- If an -ing word names an activity, classify it as a gerund.
Consider The documents signed yesterday are valid. Signed is a past participle because it modifies documents and compresses the documents that were signed yesterday.
Consider Signing the documents, the director smiled. Signing is a present participle in an introductory phrase, and the director is the understood subject.
Expert Rules for Clearer Writing
Rule 1: Analyze the auxiliary before analyzing the ending. The distinction between is running, has run, and was run depends heavily on the auxiliary construction, not merely on the word’s appearance.
Rule 2: Do not replace every participial phrase with passive voice. A phrase such as Built in 1920, the theater remains open is efficient, but a full clause is better when the builder, date relationship, or reason matters.
Rule 3: Treat participles as compressed clauses. Expand the phrase mentally. If the expanded clause produces an impossible subject, the original sentence probably contains a dangling modifier.
Rule 4: Teach irregular forms in three-part sets. Learning break, broke, broken prevents the common errors has broke and did broken more efficiently than memorizing broken alone.
Rule 5: Distinguish adjective meaning from verb meaning. In The door is closed, closed may describe a current state. In The door was closed by the guard, the same form participates in a passive verb phrase.
FAQ
Is “-ing” always a present participle?
No. -ing is a present participle when it forms a progressive verb phrase or modifies a noun, as in is running or the running water. It is a gerund when it functions as a noun, as in Running improves health or I enjoy running.
Is a past participle the same as past tense?
No. Simple past and past participle sometimes have the same form, as with walked, but they differ in function. She walked home uses simple past, while She has walked home uses the past participle after has. Irregular verbs make the contrast visible: went versus gone.
Can a present participle be passive?
A present participle itself usually expresses an active or ongoing relationship, but passive progressive constructions use being + past participle, as in The bridge is being repaired. The passive element is being repaired, not repairing.
Can a past participle be active?
Yes. A past participle forms an active perfect construction with have, as in The researcher has published the results. The researcher performs the action. Past participles can also function as adjectives without expressing either active or passive voice clearly.
What is the difference between “I am bored” and “I am boring”?
I am bored means that I experience boredom. I am boring means that I cause boredom or behave in an uninteresting way. The -ed form commonly describes the experiencer, while the -ing form commonly describes the cause.
Should formal writing avoid participial phrases?
No. Participial phrases are useful when the relationship is short, logical, and unambiguous. Formal writers should avoid them when they conceal the actor, create a dangling modifier, compress several uncertain time relationships, or make a technical sentence harder to interpret.
The Bottom Line
A participle is a verb form that can modify a noun or combine with an auxiliary verb. The present participle always ends in -ing and commonly appears in progressive constructions, while the past participle uses regular -ed or an irregular third form and commonly appears in perfect, passive, and result-state constructions.
The most accurate answer to whats a participle present participle vs past participles is not simply “active versus passive.” Form, auxiliary, syntactic function, and the noun’s relationship to the action all matter. Use -ing for progressive or activity-related meanings, use the correct past participle after have and in passive structures, and check every introductory phrase for a clear grammatical subject.
