1. Two actions, one already completed
Having + past participle forms a perfect participle clause: a non-finite clause referring to an earlier action or experience. With finish, it explicitly shows completion before the main action. However, Having known her for years, I trust her does not mean the acquaintance has ended.
This relationship can often be expressed with a full clause using “after” or causal “because”. In the following examples, the action with having is completed first and the main action happens afterwards; this also depends on the verb’s meaning.
Having + V3, + subject + finite verb
- subject / S —
- The grammatical subject: who or what the clause is about; the verb agrees with it. In The book was written, the book is the subject, although someone else does the action.
- verb / V —
- A word for an action or state, such as work or be. The pattern determines its form.
- V3 / past participle —
- The third verb form: worked, gone, seen. Used after have/has or in the passive, for example; it is not always the same as V2.
Having finished the call, Marta wrote a summary.
Having finished the call, Marta wrote a summary.
Marta finished the call first and then wrote a summary.
Having lost his key, Leo called a neighbour.
Having lost his key, Leo called a neighbour.
Losing the key happened earlier and explains the later call.
2. Form: having and specifically the past participle
Having must be followed by the past participle, or V3. For regular verbs, this is usually an -ed form: finish → finished, check → checked. For irregular verbs, V3 must be learnt separately: write → written, take → taken, see → seen, go → gone.
Having does not change for person or number here. Do not follow it with a base form, Past Simple form or to-infinitive: not having finish, having wrote or having to read when expressing a completed earlier action.
having + finished / checked / written / taken / seen
Having written the address down, Priya found the building.
Having written the address down, Priya found the building.
Written is the past participle of write; wrote does not fit here.
Having seen the notice, we changed our route.
Having seen the notice, we changed our route.
Seen is the V3 form of see; the action was completed before the change of route.
Having checked every page, I sent the document.
Having checked every page, I sent the document.
Checked is the regular -ed form after having.
3. The understood agent must match the subject
An ordinary participle clause does not name its own subject. We understand the action with having to be performed by the subject of the main clause. In Having read the email, Sara replied, Sara performs both actions.
If the main-clause subject could not have performed the first action, the result is a dangling or misrelated participle: a wrongly attached clause. Having finished my shift, the rain started grammatically attributes finishing the shift to “the rain”. When the agents differ, a full clause with after, because or when is safer.
Having read the email, Sara replied at once.
Having read the email, Sara replied at once.
Sara both read the email and replied.
Having completed the course, the students received certificates.
Having completed the course, the students received certificates.
The subject students logically performs both actions.
After the intern had gathered the data, the manager wrote the report.
After the intern had gathered the data, the manager wrote the report.
The agents differ, so a full after-clause is clearer than a clause without its own subject.
4. Context shows time, cause or both
A perfect participle refers to an earlier experience or action but does not specify a conjunction. With completed actions, the relationship may be mainly temporal: saving a file first, then closing the laptop. In another sentence, the earlier event also explains the cause: missing a train and therefore taking a taxi.
Therefore, do not mechanically interpret Having missed the train only as “after missing the train”. A natural paraphrase can use “because” if the following action is a consequence. Do not infer causation where the context supplies only sequence.
Having saved the file, I closed the laptop.
Having saved the file, I closed the laptop.
The sentence primarily orders two completed actions.
Having missed the last train, we booked a hotel room.
Having missed the last train, we booked a hotel room.
Missing the train happened earlier and explains the booking.
Having forgotten her password, Mina asked for help.
Having forgotten her password, Mina asked for help.
The context naturally links the earlier event to the reason for asking.
5. Contrast with simple -ing and a full after-clause
A simple -ing clause often describes a simultaneous, background or closely connected action: Walking home, Jo listened to a podcast. Having + V3 explicitly places completion of the first action earlier: Having walked home, Jo took off her wet coat.
Simple -ing sometimes also permits a sequential reading, so do not label every such version ungrammatical. In this lesson, choose having + V3 when the instructions explicitly ask you to emphasise completion before the next action.
The full construction After Jo had finished the report, she sent it conveys the same basic sequence and can be more natural in conversation or when a separate subject must be named. It is a grammatical alternative, not an error; it simply does not fulfil an exercise that explicitly requires having + V3.
Walking home, Jo listened to a podcast.
Walking home, Jo listened to a podcast.
Walking and listening happen at the same time.
Having walked home, Jo took off her wet coat.
Having walked home, Jo took off her wet coat.
Jo finished the walk home first, then took off her coat.
After Jo had finished the report, she sent it.
After Jo had finished the report, she sent it.
The full after-clause explicitly names the subject and expresses the same sequence of events.
6. Time, position and register
A participle clause has no grammatical tense of its own. The finite verb in the main clause and the context set the time of the whole situation: I sent is past, I can confirm expresses a present ability, and they will apply is future. In every case, having + V3 only places its own action earlier.
The clause often comes first and is separated by a comma. It can also follow the main clause, especially when adding a reason or explanation: I understood the problem, having read the full note.
These concise clauses are especially characteristic of written, academic, journalistic or literary styles. In ordinary conversation, after or because often sounds simpler. Register suitability does not by itself make a grammatical version right or wrong.
Having checked the figures, I can confirm the total.
Having checked the figures, I can confirm the total.
The checking is already finished; can confirm concerns the present.
Having completed the training, they will be ready to apply.
Having completed the training, they will be ready to apply.
Completion of the training precedes future readiness.
I understood the problem, having read the full note.
I understood the problem, having read the full note.
The final clause explains that the reading happened earlier.
7. Negation and using the pattern yourself
When the earlier action did not happen, put not before having: Not having received a reply, Dan checked the spam folder. Having still requires V3 after it.
In your own answer, identify the events and their agent. For a completed action, check that it happened earlier; for a negative, check that it had not happened by the main reference point. Then choose V3 and add the main clause with an explicit subject.
The fixed expression Having said that often introduces a contrast in discourse. Grammatically it contains a perfect participle, but its specific pragmatic meanings are not the target of this lesson. Similarly, passive having been + V3 belongs to a neighbouring rule.
Not having + V3, + subject + finite verb
- subject / S —
- The grammatical subject: who or what the clause is about; the verb agrees with it. In The book was written, the book is the subject, although someone else does the action.
- verb / V —
- A word for an action or state, such as work or be. The pattern determines its form.
- V3 / past participle —
- The third verb form: worked, gone, seen. Used after have/has or in the passive, for example; it is not always the same as V2.
Not having received a reply, Dan checked the spam folder.
Not having received a reply, Dan checked the spam folder.
Not negates the earlier action; received remains V3.
Not having read all the options, I postponed my decision.
Not having read all the options, I postponed my decision.
The same person had not read all the options and therefore postponed the decision.
Having practised the talk twice, I felt more confident.
Having practised the talk twice, I felt more confident.
This personal example combines completed preparation with its later result.
Common mistakes
Incorrect:Having finish the report, he sent it.
Correct:Having finished the report, he sent it.
After having, use the past participle finished, not the base form finish.
Incorrect:Having wrote the address down, Priya found the building.
Correct:Having written the address down, Priya found the building.
The V3 form of write is written; wrote is Past Simple.
Incorrect:Having finished my shift, the bus took me home.
Correct:Having finished my shift, I took the bus home.
The understood agent of the participle clause must match the subject of the main clause: I finished the shift, not the bus.
Incorrect:Not having knew the answer, I checked the guide.
Correct:Not having known the answer, I checked the guide.
Negation does not change the form: having requires V3 known, not Past Simple knew.
