You will build causatives from verb pairs that must be learned together. Here “irregular” means that the verb selects a less predictable suffix family; the suffix vowels still follow harmony.

The idea

Learn the pair first: pişmek → pişirmek, çıkmak → çıkarmak. After removing the infinitive, add -ır/-ir/-ur/-ür or -ar/-er as required by that verb. The first family uses four-way vowel harmony, the second two-way harmony. These families are not freely interchangeable. Add tense or an infinitive afterwards: piş + ir + mek. Keep k in çıkarmak and ç in uçurmak. The lexicalized form gidermek means to remove or resolve; its base git- appears as gid- before -er.

Watch out

Do not skip the causative when adding tense: pişti says that something cooked, while pişirdi says someone cooked it. Nor can the last vowel alone tell you to choose -ir rather than -er: learn the verb pair, not just the harmony pattern.

Try it yourself

  1. Form the causative infinitive: to cook the lentils.

    Show answer or example answer

    pişirmek

    pişirmek: the lentils are cooked by someone. Start with piş, add ir, then mek. Without ir, pişmek describes the food cooking.

  2. Use the causative in -ar and the infinitive ending: to take the key out.

    Show answer or example answer

    çıkarmak

    çıkarmak: the requested -ar attaches to çık without changing k. The resulting verb means taking something out; çıkmak describes going or coming out.

  3. Complete in the past, first person singular: I dropped my pen just now.

    Show answer or example answer

    düşürdüm

    düşürdüm: the pen fell because of the speaker’s action. In düş + ür + dü + m, ür makes “fall” into “drop”, dü marks the past and m marks “I”.

  4. Form the infinitive meaning to resolve the problem.

    Show answer or example answer

    gidermek

    gidermek: the object is a problem, so the intended meaning is resolving it. This established verb has d and -er; it is not a general instruction to make someone go.
