Forming the present perfect
Two parts of one construction
The present perfect links an earlier action or state with the present. This lesson focuses on forming it correctly: auxiliary have or has plus the past participle, the third verb form, or V3. Both parts are needed: have/has marks the grammatical construction, while the main verb identifies the action or state.
This is not a rule that “the action must be finished”. It can describe a completed result, experience up to now or a state that started earlier and continues now. Its meaning is not restricted to a completed past action.
subject + have/has + V3
- 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.
- 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.
We have cleaned the kitchen.
We have cleaned the kitchen.
Have cleaned reports a completed action, presented here with a currently clean kitchen as its result.
I have known Anna for two years.
I have known Anna for two years.
The acquaintance continues now. Have known is the same present perfect form, although the state has not ended.
Have or has: look at the subject
Use have with I, you, we and they; has with he, she and it. The pattern also applies to nouns: my brother names one person and takes has; my parents names several and takes have. You takes have whether it addresses one person or several.
Changing the subject changes the auxiliary, but not V3. Do not add -s to the participle for he or she.
I/you/we/they have sent • he/she/it has sent
My brother has sent the photo.
My brother has sent the photo.
My brother is singular, so use has; sent remains the participle of send.
My parents have sent the photo.
My parents have sent the photo.
The plural subject requires have, while sent stays unchanged.
V3: not always the same as the past simple
Regular verbs have identical V2 and V3: work — worked — worked; live — lived — lived. Spelling follows the usual rules: add d after final e, while study becomes studied. For irregular verbs, check the third column: go — went — gone; see — saw — seen; write — wrote — written.
Not every irregular verb has three different forms: send — sent — sent, cut — cut — cut. Be has participle been, and have has had. Have had and has had are therefore correct combinations: the first verb is auxiliary and the second carries the main-verb meaning of have.
She has written a shopping list.
She has written a shopping list.
Has requires written rather than wrote.
We have had lunch.
We have had lunch.
Have forms the tense; had is the participle of have in have lunch.
He has cut the bread.
He has cut the bread.
Cut is already the participle; no -ed is needed.
Negatives: not after have/has
To make a negative, place not after have or has. The main verb remains a participle. Do, does and did are not needed to form this negative.
Have not contracts to haven’t; has not to hasn’t. Complete sentences can also use I’ve not or she’s not: I’ve not seen it; she’s not sent the file. Full forms and contractions express the same negative; contractions are common in speech.
subject + have/has + not + V3
- 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.
- 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.
I haven't opened the box.
I haven't opened the box.
Haven’t = have not. Opened does not revert to open.
She has not paid the bill.
She has not paid the bill.
She takes has not, and paid is the participle of pay.
Questions: the auxiliary moves first
In an ordinary yes/no question, put have or has before the subject. The participle stays after the subject. Do not add do or did or change the participle to a base verb.
To ask what or where, place that question word before the construction. Here we practise questions whose subject is already known: What have you bought? Subject questions such as Who has called? have a different structure and are not this set’s target.
Have/Has + subject + V3? • What/Where + have/has + subject + V3?
- 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.
- 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.
Has the bus arrived?
Has the bus arrived?
The bus is singular, so the question begins with Has.
What have you bought?
What have you bought?
What asks about the purchase; you remains subject, and bought is the participle.
Contractions and short answers are different
In a complete statement, I have → I’ve, you have → you’ve, we have → we’ve, they have → they’ve; he has → he’s, she has → she’s, it has → it’s. The apostrophe marks omitted letters. She’s sent the email means She has sent the email. But ’s can also mean is: She’s tired means She is tired. Read the whole sentence, not just the contraction.
In a short answer, repeat have or has, not the whole action: Have you eaten? — Yes, I have. / No, I haven’t. Retain the person asked about: Has Eva called? — Yes, she has. Affirmative I’ve and she’s cannot end such an answer alone. Full Yes, I’ve eaten is correct.
Yes, I/you/we/they have. • Yes, he/she/it has. • No, … haven’t/hasn’t.
She's finished the report.
She's finished the report.
The object the report clarifies the verbal meaning: ’s = has.
Have you checked the address? — Yes, I have.
Have you checked the address? — Yes, I have.
Do not contract have to ’ve in this short confirmation; checked the address is already understood from the question.
Has he replied? — No, he hasn't.
Has he replied? — No, he hasn't.
Negative hasn’t can end a short answer.
From the form to your own statement
Before answering, check who acts, whether you are stating, denying or asking, and which participle is needed. Then read the whole sentence: does it preserve your meaning? Do not interpret auxiliary have as a separate possession verb.
Forming the tense does not replace choosing a tense. I sent the email yesterday is correct past simple for a specific completed time. I’ve sent the email gives another perspective, a summary up to now. A present-perfect formation task requires that construction; another grammatical tense may miss its learning condition without becoming universally incorrect.
I've packed my bag, but I haven't found my keys.
I've packed my bag, but I haven't found my keys.
The two facts have different polarity: a packed bag and missing keys. Both clauses contain an auxiliary and a participle.
We have lived here for three years. We still live here.
We have lived here for three years. We still live here.
Have lived does not mean we have moved away. The second sentence explicitly confirms that residence continues.
Common mistakes
Incorrect:I has seen that film.
Correct:I have seen that film.
I requires have; seen needs no change.
Incorrect:She has wrote a letter.
Correct:She has written a letter.
Wrote is V2; has requires V3 written.
Incorrect:We have not eat lunch.
Correct:We have not eaten lunch.
Not does not remove the participle requirement: eat → eaten.
Incorrect:Does he has paid the bill?
Correct:Has he paid the bill?
The present-perfect question is formed by has before the subject; does is unnecessary.
Incorrect:Yes, I've.
Correct:Yes, I have.
An affirmative short answer ends with full have. I’ve requires a continuation, such as I’ve checked it.
