Turkish has a small but expressive family of compound verbs in which a main verb is welded to one of four auxiliaries — vermek, durmak, gelmek, kalmak — through a linking vowel. These are not the noun-plus-light-verb compounds of etmek and olmak; they are lexical aspect markers. Each one colours the action with a nuance — speed, continuity, persistence, or frozenness — that English usually expresses with an adverb or particle: "just," "keep on," "all along," "be left." The most common of them, -(y)Iver, is everyday colloquial speech; the others range from frequent to distinctly literary.
How the welding works
Each compound takes the main verb as a converb and fuses the auxiliary directly onto it, written as a single word. The linking vowel is the buffer -y- plus a harmonising vowel:
- -(y)Iver uses the high vowel converb -(y)I
- ver- (suddenness, ease).
- -(y)Adur, -(y)Agel, -(y)Akal use the low vowel converb -(y)A
- dur- / gel- / kal- (continuation, persistence, frozen state).
Because they fuse, you must read the spelling carefully: gid-iver, yap-ıver, bak-akal, uyu-yakal. The buffer -y- appears only after a vowel-final stem (uyu-y-akal, oku-y-uver). Tense and person then attach to the auxiliary, never to the main verb.
-(y)Iver: suddenness, ease, and "just do it"
This is the tezlik fiili ("quickness verb"). It adds one of two closely related flavours: the action happens suddenly/unexpectedly, or it is done quickly and easily, with no fuss. In the imperative it is the natural way to say "just (do it real quick)."
Sen otur, ben kapıyı açıveririm.
You sit down, I'll just get the door real quick.
Markete kadar gidiver de bir ekmek al.
Just pop over to the shop and grab a loaf of bread.
Çocuk birden bağırınca hepimiz gülüverdik.
When the child suddenly shouted, we all burst out laughing.
The first two carry the "quick and easy, no big deal" reading; the third carries the "all of a sudden" reading. Both come from the same suffix, and context decides which. The vowel harmonises to the stem: aç-ıver, git → gid-iver, gül-üver, ol-uver. In casual speech -(y)Iver is genuinely frequent — softening a request, downplaying an effort, or marking something that just happened.
Merak etme, bu işi bir çırpıda hallediveririz.
Don't worry, we'll sort this out in no time.
-(y)Adur: keep on doing it (continuation)
The sürerlik fiili ("continuation verb") with durmak ("to stand/stay") means keep doing the action — carry on, in the meantime. It often tells one person to keep an activity going while something else is arranged.
Sen yemeği hazırlayadur, ben de masayı kurayım.
You keep getting the food ready, and I'll set the table.
Onlar konuşadursun, biz çoktan yola çıkmıştık bile.
Let them keep talking — we'd long since set off anyway.
The flavour is "continue without stopping, while the rest of the situation moves on." Compare this with the simple progressive -Iyor: hazırlıyorsun just states "you are preparing," whereas hazırlayadur says "carry on preparing, keep at it." This auxiliary is somewhat formal and less common than -(y)Iver; in casual speech people often prefer a converb plus durmak spelled separately, but the fused literary form is what you meet in writing.
-(y)Agel: it has gone on all along (habitual continuity)
With gelmek ("to come"), the converb yields a sense of an action that has continued from the past up to the present — a long-standing, habitual, almost traditional continuity. This one is firmly (literary) and characteristic of formal or elevated prose.
Bu gelenek yüzyıllardır köyde süregelmiştir.
This tradition has gone on in the village for centuries.
Halkın yöneticilerine duyduğu güvensizlik öteden beri olagelmiştir.
The people's distrust of their rulers has existed all along.
The two productive members you will actually meet are süregelmek ("to continue/persist over time") and olagelmek ("to have been the case all along"). Outside these, -(y)Agel is rare and bookish; do not coin new ones. Note that süregelmek is so lexicalised it functions as an ordinary dictionary verb meaning "to persist."
-(y)Akal: left frozen in a state
With kalmak ("to remain/stay"), the converb describes someone left stuck in a state — frozen, caught, unable to move on, usually from shock, surprise, or being overtaken by an event. This is the frozenness auxiliary.
Manzara o kadar güzeldi ki öylece bakakaldık.
The view was so beautiful that we were just left staring.
Haberi duyunca olduğu yerde donakaldı.
When he heard the news, he froze on the spot.
Ders çalışırken masada uyuyakalmışım.
I seem to have fallen asleep at the desk while studying.
The lexicalised members here are very common: bakakalmak ("to be left staring"), donakalmak ("to freeze, be dumbstruck"), şaşakalmak ("to be left astonished"), and especially uyuyakalmak ("to fall asleep / doze off accidentally"). That last one is everyday speech, not literary at all. Notice in the third example that it pairs naturally with the evidential -mIş (uyuyakalmışım), because falling asleep is something you did without realising — you discover it after the fact, which is exactly the evidential's territory.
Why these matter and how productive they are
English leans on adverbs and particles for these meanings: just, real quick, keep on, all along, be left (staring). Turkish folds the same nuances into the verb itself through these auxiliaries, which is why competitors that skip them leave learners over-relying on adverbs and sounding flat. But productivity varies sharply, and an honest account must say so:
- -(y)Iver is broadly productive — you can attach it to most verbs and be understood.
- -(y)Akal survives mainly in a closed set: bakakalmak, donakalmak, şaşakalmak, uyuyakalmak, kalakalmak.
- -(y)Adur is restricted and formal.
- -(y)Agel is essentially frozen into süregelmek and olagelmek.
There is no clean rule for which new verbs accept which auxiliary — outside -(y)Iver, treat them as a learnable list rather than a free pattern. They are all built on a converb, so they sit alongside the converbs in -(y)Ip and -(y)ArAk as part of the same converb-plus-verb machinery.
Common mistakes
Sen otur, ben kapıyı açıver.
Incorrect person — the auxiliary carries the agreement; for 'I'll get it' you need the first-person açıveririm, not the bare stem.
Sen otur, ben kapıyı açıveririm.
You sit down, I'll just get the door.
Masada uyudum kaldım.
Incorrect — 'dozed off' is the fused single verb uyuyakalmak, not two separate words.
Masada uyuyakaldım.
I fell asleep at the desk.
Bu gelenek köyde süregelir hâlâ devam ediyor.
Incorrect — süregelmek already means 'continues over time'; pairing it with a redundant 'still continues' clause is tautological.
Bu gelenek köyde hâlâ süregeliyor.
This tradition still continues in the village.
Manzaraya bakakaldı çok güzeldi.
Incorrect — bakakalmak takes the dative complement and needs a linking subordinator; run-on juxtaposition is ungrammatical here.
Manzara çok güzel olduğu için bakakaldı.
Because the view was so beautiful, he was left staring.
Ben gidiverirsin markete.
Incorrect — the subject and the agreement clash; 'I'll pop over' is gidiveririm, while gidiverirsin is 'you'.
Ben markete gidiveririm.
I'll just pop over to the shop.
Key takeaways
- Four auxiliaries fuse onto a converb to mark lexical aspect: -(y)Iver (suddenness/ease), -(y)Adur (continuation), -(y)Agel (habitual continuity), -(y)Akal (frozen state).
- -(y)Iver is everyday and broadly productive; it softens imperatives beautifully (bakıver = "just have a quick look").
- -(y)Akal is mostly a closed set, but uyuyakalmak ("doze off") is essential colloquial vocabulary.
- -(y)Adur is formal; -(y)Agel is (literary) and effectively limited to süregelmek and olagelmek.
- They are written solid, with a buffer -y- after vowel-final stems, and tense/person attach to the auxiliary, never the main verb.
