You will build verb forms meaning “whenever” or “as something happens”. Start with the bare verb stem; a passive or ability suffix can already be attached to it.
The idea
Choose the first vowel from the last vowel of the stem: a/ı → ı, e/i → i, o/u → u, ö/ü → ü. The ending finishes in -ça after a back vowel and -çe after a front vowel. It starts with t after ç f h k p s ş t and d elsewhere. Add the whole ending directly, even after a vowel: oku + dukça. It links repeated events or accompanying change; the main verb supplies tense. No person ending is inserted into this converb.
| Last vowel | After a vowel or voiced consonant | Example | After a voiceless consonant | Example |
|---|---|---|---|---|
| a, ı | -dıkça | yazdıkça | -tıkça | baktıkça |
| e, i | -dikçe | geldikçe | -tikçe | gittikçe |
| o, u | -dukça | okudukça | -tukça | konuştukça |
| ö, ü | -dükçe | gördükçe | -tükçe | düştükçe |
Examples
- Fotoğrafa baktıkça gülümsüyorum.I smile whenever I look at the photograph.
- Çorba soğudukça tadı değişiyor.As the soup cools, its taste changes.
- Bu yolu yürüdükçe rahatlıyorum.The more I walk this route, the more relaxed I feel.
- Bu öykü okundukça farklı yorumlar ortaya çıkıyor.As this story is read, different interpretations emerge.
- Düşünceler yazıldıkça netleşiyor.Thoughts become clearer as they are written down.
- Okuyabildikçe yeni şeyler öğreniyorum.Whenever I can read, I learn new things.

No Turkish device voice is available. You can still read the text.
Watch out
Do not turn the k into ğ or insert a possessive ending as in other forms built with -dik. Here k stays before ç: gördükçe. In gittikçe, the stem’s t also stays because the suffix starts with a consonant.
Try it yourself
Write the form meaning “whenever one sees”, from görmek.
Show answer or example answer
gördükçe
gördükçe: gör- ends in voiced r, and rounded front ö selects ü. Seeing supplies the recurring occasion, rather than a past-tense statement.
Add the lesson’s suffix to the stem of gitmek; write the whole word.
Show answer or example answer
gittikçe
gittikçe: git- ends in voiceless t, so another t begins the suffix. Both are written. Depending on context, this word can also mean “increasingly”.
Complete: The more we talk, the fewer problems there are. Use konuşmak.
Show answer or example answer
konuştukça
konuştukça: ş requires initial t, and the last vowel u requires u. The subject biz is already explicit; no “we” ending belongs inside this form.
Build “whenever one can read”; write the whole word, keeping the ability suffix.
Show answer or example answer
okuyabildikçe
okuyabildikçe: the suffix follows okuyabil-, whose last vowel is i, so it is -dikçe. Choosing by the original u in oku- would overlook the intervening ability suffix.

Build one form after a vowel, one after a voiceless consonant and one after an ability suffix. Use each in a sentence and say whether it describes repetition or gradual change.
