Build an “after doing” phrase from a verb stem. The table gives all eight forms; the word chains isolate the verb form, which you follow with sonra.

The idea

Remove -mek or -mak, then attach the form in the table. Its first vowel follows the stem: a/ı → ı, e/i → i, o/u → u, ö/ü → ü. Use initial t after ç f h k p s ş t, otherwise d. The ending is always -tan or -ten after k, and sonra stays separate. The phrase places one completed action before another; it is not itself a past-tense verb, so it also works in a future plan.

Watch out

Do not carry the softened stem of gidiyorum into gittikten sonra. The suffix begins with a consonant, so git- keeps its t; the suffix adds another. Do not add a personal ending here: geldikten sonra, even when the speaker is “I”.

Try it yourself

  1. gitmek → ___ (sonra)

    Show answer or example answer

    gittikten sonra

    gittikten sonra: the stem is git-. Its final t requires -tikten, and its i selects the front unrounded vowel; both letters t remain.

  2. okumak → ___ (sonra)

    Show answer or example answer

    okuduktan sonra

    okuduktan sonra: removing -mak leaves oku-. The final u calls for -duktan. No buffer y is needed before the consonant d.

  3. görmek → ___ (sonra)

    Show answer or example answer

    gördükten sonra

    gördükten sonra: gör- ends in voiced r, so the suffix starts with d. The rounded front vowel ö selects ü; k stays before -ten.

  4. yapmak → ___ (sonra)

    Show answer or example answer

    yaptıktan sonra

    yaptıktan sonra: yap- ends in voiceless p, which selects initial t. Its a requires dotless ı, giving -tıktan; sonra is a separate word.
