Kural
Geçmiş hakkında çıkarım
Modals of past deduction, bugün görülen ipuçlarından yola çıkarak geçmişte olmuş bir şey hakkında mantıklı bir sonuç çıkarmayı sağlar. Türkçede “Yerler ıslak, gece yağmur yağmış olmalı” derken yaptığımız şey budur. Yapı: modal + have + fiilin üçüncü hâli. Kesinlik derecesine göre üç seçenek vardır.
Must have
(1) Must have + üçüncü hâl: neredeyse kesin olumlu çıkarım. The pavement is soaking wet; it must have rained in the night. David got the promotion; he must have worked very hard.
Can't have, couldn't have
(2) Can't have ya da couldn't have + üçüncü hâl: neredeyse kesin olumsuz çıkarım, yani geçmişte olmasının imkânsız olduğu. He can't have taken the laptop; he was on holiday all week. You couldn't have seen Sarah in town yesterday; she's in Tokyo.
Might have, may have, could have
(3) Might have, may have ya da could have + üçüncü hâl: geçmişte olmuş olabileceği düşünülen ama kanıtlanamayan ihtimal. Emma didn't answer her phone; she might have been asleep. They could have taken a wrong turn.
Kısaltma ve of hatası
Konuşmada have genellikle 've olarak kısaltılır ve zayıf okunur: must've, might've, can't've. Bu yüzden yazıda sık sık yanlışlıkla of yazılır.

How to read this B1 topic
At B1, grammar links ideas: condition, result, reported meaning, experience, and narrative order.
1. Name the relationship
Ask whether the sentence gives a condition, contrast, cause, report, or result.
If it rains, we will stay home.
2. Separate time from aspect
Finished event, visible result, duration, and background action use different forms.
I had left before she arrived.
3. Test both clauses
In complex sentences, the second half often proves the first half.
I wish I knew.
Modal verbs
Modals are followed by the base verb. They do not take third-person -s.
| Meaning | Present / future | Past or perfect reference | Example |
|---|---|---|---|
| ability | can | could / was able to | She can swim. |
| obligation | must / have to | had to | We must leave. |
| advice | should | should have + participle | You should rest. |
| deduction | must / might / can't | must have / might have / can't have | He must be tired. |
Contrasts that often decide the answer
Event or background
Simple forms move events forward; continuous forms show an action in progress.
I left while she was talking.
Fact or stance
Modals, hedges, and reporting structures show how certain or responsible the speaker sounds.
This may indicate a problem.
Clause or compressed phrase
Advanced writing often compresses full clauses into participle, noun, or prepositional phrases.

İstisnalar
Geçmişte bir şeyin imkânsız olduğunu söylerken must not have değil, can't have ya da couldn't have kullanılır: He can't have said that. Amerikan İngilizcesinde must not have zayıf bir olumsuz tahmin olarak duyulabilir (She must not have seen me, beni görmemiş olmalı), ama imkânsızlık bildirmez. Could have bir başka anlamda, yapılabilecekken yapılmamış bir şeyi de anlatır: I could have won the race, but I fell.
