Build conditional forms in two positions: after an aorist form, as in gelirse, and directly after a verb stem, as in gelsem. This page focuses on those two patterns.
The idea
Use -se after e, i, ö, ü and -sa after a, ı, o, u, looking at the last vowel before the suffix. The consonant s stays the same. In gel-ir-se, the aorist remains before the conditional: “if he or she comes”. In gel-se-m, the suffix follows the stem and -m marks “I”: “if I were to come”. The bare-stem pattern can express a hypothesis or a wish, depending on context. A vowel-final stem takes it directly: bekle-se, oku-sa.
| Last vowel | Suffix | Base | Conditional form |
|---|---|---|---|
| e, i, ö, ü | -se | gel | gelse |
| a, ı, o, u | -sa | bak | baksa |
| i | -se | gelir | gelirse |
| a | -sa | yağar | yağarsa |
| e | -se | bekle | beklese |
| u | -sa | oku | okusa |
| i | -se | git | gitse |
Examples
- Yağmur yağarsa pencereyi kapatırım.If it rains, I will close the window.
- Erken gelirsen birlikte yemek yaparız.If you come early, we will cook together.
- Bu kitabı okursan konuyu anlarsın.If you read this book, you will understand the topic.
- gelirseif he or she comesgelir-ir / -ar / -er: the aorist (gelir, yapar)se-se / -sa: the conditional suffix
- yağarsaif it rainsyağar-ir / -ar / -er: the aorist (gelir, yapar)sa-se / -sa: the conditional suffix

Watch out
Do not remove the aorist merely because English uses “if”: gelirse and gelse are not freely interchangeable. Nor does git- become gid- before -se: write gitse, because the suffix begins with a consonant.
Try it yourself
Add the conditional to gelir: if he or she comes. Write the whole word.
Show answer or example answer
gelirse
gelirse: the supplied base gelir already contains the aorist. Keep its r; the last vowel i selects -se. No person ending is added for he or she.
Add the conditional to yağar: if it rains. Write the whole word.
Show answer or example answer
yağarsa
yağarsa: start with yağar, whose last vowel is a. Adding -sa makes the rain a condition; the ğ in the stem stays.
Use the bare stem gel- with the conditional and “I”: if I were to come.
Show answer or example answer
gelsem
gelsem: the prompt asks for the bare-stem hypothesis with “I”. Join gel, se and m; adding -ir would instead produce gelirsem.
Use the bare stem git- with the conditional, third person singular: if he or she were to go.
Show answer or example answer
gitse
gitse: the following s is a consonant, so the final t of git stays. Its vowel i calls for -se, with no extra person ending here.
