📊 Conditional Tiplerine Genel Bakış
| Tip | If-clause | Main Clause | Anlam |
|---|---|---|---|
| Zero | If + Present Simple | Present Simple | Genel gerçekler, bilimsel yasalar |
| First | If + Present Simple | will + V1 | Gerçekçi gelecek koşul |
| Second | If + Past Simple | would + V1 | Hayali / gerçek dışı şimdiki durum |
| Third | If + Past Perfect | would have + V3 | Geçmişe dair pişmanlık / gerçek dışı |
| Mixed | If + Past Perfect | would + V1 | Geçmişteki durum → şimdiki sonuç |
🟢 Zero Conditional
Her zaman doğru olan gerçekler, bilimsel yasalar ve genel alışkanlıklar için kullanılır. Her iki cümlede de Present Simple kullanılır. "If" yerine "when" kullanılabilir.
Present Simple , Present Simple
🔵 First Conditional
Gerçekleşmesi mümkün olan gelecek koşullar için kullanılır. If-clause'da Present Simple, ana cümlede will + V1 kullanılır.
Present Simple , will + V1
⚠️ If-clause'da will kullanılmaz
If-clause içinde "will" kesinlikle olmaz.
✗ If it will rain, we will stay inside.
✓ If it rains, we will stay inside.
can, may, might, should da First Conditional ana cümlesinde kullanılabilir. "If you study hard, you may pass" geçerli.🟡 Second Conditional
Şu anda gerçek olmayan ya da gerçekleşmesi pek mümkün görünmeyen durumları ifade eder. If-clause'da Past Simple, ana cümlede would + V1 kullanılır.
Past Simple , would + V1
⚠️ "Were" her özneyle kullanılır
Formal ve akademik yazıda (YDS metinlerinde) tüm öznelerle were kullanılır — "was" değil.
✗ If she was taller, she would play basketball.
✓ If she were taller, she would play basketball.
⚠️ Would'dan sonra V1 kullanılır — V3 değil
- ✗ If he studied, he would passed.
- ✓ If he studied, he would pass.
🔴 Third Conditional
Geçmişte gerçekleşmemiş durumları ve pişmanlıkları ifade eder. If-clause'da Past Perfect, ana cümlede would have + V3 kullanılır. YDS'nin en çok tuzak kurduğu conditional tipidir.
Past Perfect (had + V3) , would have + V3
⚠️ "Would have + V3" yapısını karıştırma
- ✗ If he had studied, he would have pass.
- ✗ If he had studied, he would passed.
- ✓ If he had studied, he would have passed.
could have + V3 veya might have + V3 da kullanılabilir. "If the funding had been approved, the project could have been completed on time." — YDS'de anlam yakınlığı sorularında bu değişim sorulur.🟦 Mixed Conditional
Geçmişte olan (ya da olmayan) bir durumun şimdiki sonucunu ifade eder. YDS'de en zor ve en çok çıkan conditional tipidir. If-clause'da Past Perfect, ana cümlede would + V1 kullanılır.
Past Perfect (had + V3) , would + V1
| Tip | If-clause | Main Clause | Zaman ilişkisi |
|---|---|---|---|
| Third | had + V3 | would have + V3 | Geçmiş koşul → geçmiş sonuç |
| Mixed | had + V3 | would + V1 | Geçmiş koşul → şimdiki sonuç |
🔗 Unless, Provided That ve Diğer Conditional Bağlaçları
YDS anlam yakınlığı sorularında "if" yerine başka bağlaçlar kullanılarak aynı anlam ifade edilir. Bu dönüşümleri bilmek kritik.
Unless = If ... not
⚠️ Unless + olumsuz fiil YANLIŞ
- ✗ Unless he doesn't study, he will fail.
- ✓ Unless he studies, he will fail.
- ✓ If he doesn't study, he will fail.
Diğer Conditional Bağlaçları
| Bağlaç | Anlam | Örnek |
|---|---|---|
provided (that) | ...koşuluyla, ancak ... ise | Provided that all tests pass, the drug will be approved. |
as long as | ...olduğu sürece | As long as demand exists, prices will remain high. |
on condition that | ...şartıyla | She agreed on condition that her name was kept private. |
supposing (that) | diyelim ki, farz et ki | Supposing the results were negative, what would you do? |
in case | ...ihtimaline karşı (önlem) | Take an umbrella in case it rains. (= ihtimale karşı) |
even if | ...olsa bile | Even if it rains, the match will continue. |
🔄 Inverted Conditionals (If'siz Koşul Cümleleri)
Akademik YDS metinlerinde "if" kullanılmadan koşul cümlesi kurulabilir. Bu yapılar anlam yakınlığı sorularında çıkar — "if" ile olan versiyona dönüştürmen gerekir.
| Normal | Inverted (If'siz) |
|---|---|
| If I were you, I would reconsider. | Were I you, I would reconsider. |
| If he had known the truth, he would have acted differently. | Had he known the truth, he would have acted differently. |
| If it should rain, the event will be postponed. | Should it rain, the event will be postponed. |

🎯 YDS'de Conditional Soruları Nasıl Çözülür?
Adım 1: Zaman çerçevesini belirle
Cümledeki zaman zarflarına bak: "now / today / currently" → Mixed veya Second. "at that time / then / yesterday" → Third. "tomorrow / next year / in the future" → First.
Adım 2: Gerçek mi, hayal mi?
Durum gerçekleşmiş ya da gerçekleşebilir görünüyorsa → Zero veya First. Gerçek dışı, hayal ya da pişmanlık ise → Second, Third veya Mixed.
Adım 3: If-clause ve main clause'un uyumunu kontrol et
Adım 4: Anlam yakınlığı sorularında bağlaç dönüşümüne dikkat et
"Unless" → "if not", "provided that" → "if", "as long as" → "if" dönüşümlerini ezberle. Inverted yapılarda ("Had she known..." = "If she had known...") anlamın değişmediğini hatırla.
V1 (base form) gelir. "Would passed / would went" gibi yazımlar kesinlikle yanlış. Seçeneklerde bu hatayı gördüğünde hemen elendirebilirsin.
