Present Perfect: Experience & Results

have/has + past participle with ever / never / just / already / yet.

We make the present perfect with the helping verb have or has plus the past participle of the main verb (I/you/we/they have, but he/she/it has): I have seen, she has gone. We use it to talk about life experiences without saying exactly when (Have you ever been to London?), and about recent actions whose result we can see now (I have lost my keys, so I can't open the door). The adverbs ever and never go before the past participle to talk about experience: 'Have you ever eaten sushi?' and 'I have never eaten sushi.' We use just for something that happened a very short time ago (She has just left) and already for something finished sooner than expected, both placed between have/has and the participle (I have already finished). The word yet is used in questions and negatives and goes at the end of the sentence: 'Have you finished yet?' and 'I haven't finished yet.' Remember that the past participle of regular verbs ends in -ed (work → worked), but many common verbs are irregular and must be learned (go → gone, see → seen, eat → eaten). For example: 'I have already done my homework, so I am free now.'

Key terms

Present PerfectA tense made with have/has + past participle. It talks about life experiences without saying exactly when (Have you ever been to London?) and about recent actions whose result we can see now (I have lost my keys, so I can't open the door).
past participle (V3)The third form of the verb, used after have/has. Regular verbs add -ed (work → worked, play → played); many common verbs are irregular and must be learned (go → gone, see → seen, eat → eaten, do → done, write → written).
have / hasThe helping verb of the present perfect. Use 'have' with I/you/we/they and 'has' with he/she/it: I have seen, she has gone.
ever / neverAdverbs of experience placed before the past participle. 'ever' is used in questions (Have you ever eaten sushi?); 'never' gives a negative meaning in positive sentences (I have never eaten sushi).
already / justAdverbs placed between have/has and the participle. 'already' means finished sooner than expected (I have already finished); 'just' means something happened a very short time ago (She has just left).
yetUsed only in questions and negatives, placed at the end of the sentence: 'Have you finished yet?' and 'I haven't finished yet.'

Forming a present perfect sentence
  1. 1Choose have or has: Subject 'She' is he/she/it, so use 'has'. (Use 'have' with I/you/we/they.)
  2. 2Add the past participle: The verb 'see' is irregular, so its participle is 'seen', not 'seed' or 'saw'.
  3. 3Put it together: She + has + seen this film → 'She has seen this film.'
Placing already and yet correctly
  1. 1Positive sentence with already: 'already' goes between have/has and the participle: 'I have already done my homework.'
  2. 2Negative or question with yet: 'yet' goes at the end and is used only in negatives and questions: 'I haven't done my homework yet.' / 'Have you done your homework yet?'
  3. 3Check the swap: Do not use 'already' at the end of a negative or 'yet' in a positive statement: say 'I have already finished' but 'I haven't finished yet.'
🚫Common mistake

Use 'has' only with he/she/it. With I/you/we/they always use 'have': say 'They have eaten', not 'They has eaten'.

🚫Common mistake

After have/has use the past participle (V3), not the past simple (V2): 'He has written a letter' (not 'wrote'), 'Have you ever been there?' (not 'went').

⚠️Caution

Use 'yet' (at the end) in negatives and questions, and 'already' (before the participle) in positive sentences. Don't swap them: 'I haven't finished yet', but 'I have already finished'.

🚫Common mistake

Don't add -ed to irregular verbs: the participles are 'lost', 'taken', 'heard', 'read', 'done' — never 'losed', 'taked', 'heared', 'readed'.

Rules

  1. 1Form: have/has + past participle. Use 'have' with I/you/we/they and 'has' with he/she/it (I have seen, she has gone).
  2. 2ever and never come before the past participle and talk about experience: 'Have you ever been there?', 'I have never been there.'
  3. 3just (a moment ago) and already (sooner than expected) go between have/has and the participle: 'She has just arrived.', 'I have already eaten.'
  4. 4yet goes at the end and is used only in questions and negatives: 'Have you finished yet?', 'I haven't finished yet.'
  5. 5Past participles: regular verbs add -ed (play → played); learn irregular ones (go → gone, see → seen, do → done, eat → eaten, write → written).
