A noun can become a verb about a new state: toz means dust, while tozlanmak means to get dusty. You will build three familiar verbs and then put one into the past tense.
The idea
With this suffix, use -lan after a back vowel (a ı o u) and -len after a front vowel (e i ö ü). The suffix often makes a verb about acquiring a quality or entering a state. It creates the verb stem; it does not mark tense or person. Attach the infinitive after it: toz-lan-mak, kir-len-mek, ev-len-mek. For a finite verb, put the tense ending after the derived stem instead: kir-len-di. The chains here keep -lan/-len together as one word-building unit.
| Last vowel | Suffix | Base | Infinitive |
|---|---|---|---|
| a, ı, o, u | -lan | toz | tozlanmak |
| e, i, ö, ü | -len | kir | kirlenmek |
| e | -len | ev | evlenmek |
Examples
- Raflar iki günde tozlandı.The shelves got dusty in two days.

Watch out
Do not treat the suffix as a freely usable translation of “become”, or interpret every verb literally. Evlenmek means to get married, not to move into a house. Learn kullanmak as to use; its spelling does not supply its meaning. Also distinguish kirlenmek (to get dirty) from kirletmek (to make something dirty).
Try it yourself
Build the infinitive from toz (dust): to get dusty.
Show answer or example answer
tozlanmak
tozlanmak: dust accumulates on the thing concerned. The o in toz selects -lan; the last vowel of the new stem is then a, so the infinitive has -mak, not -mek.
Build the infinitive from kir (dirt): to get dirty.
Show answer or example answer
kirlenmek
kirlenmek: the subject gets dirty. The base kir contains front i, which leads to -len and then -mek. Making another thing dirty would require kirletmek.
Build the established verb from ev (house): to get married. Write the infinitive.
Show answer or example answer
evlenmek
evlenmek: the requested meaning is getting married. Although ev means house, the established verb names marriage. Its front vowel gives -lenmek.
Complete in the simple past: My apron got dirty with paint. Use kirlenmek.
Show answer or example answer
kirlendi
kirlendi: the apron undergoes the change. Remove infinitive -mek from kirlenmek and add -di to kirlen-; the third-person singular needs no further person ending.
