Combined voice (birleşik çatı) in Turkish (B2)

what is it?

Turkish verbs can carry more than one voice suffix at the same time. When two or more voice suffixes are stacked on a single stem, the result is called a birleşik çatı (combined voice). The suffixes must appear in a strict order: reflexive (-in-/-ın-) or reciprocal (-iş-/-ış-) come first, then causative (-dir-/-tir-), which may itself be doubled, and finally passive (-il-/-ın-). The last suffix in the chain determines the transitivity of the whole verb: a passive ending makes the verb intransitive; a causative ending makes it transitive. Only a passive suffix may be added on top of an already-passive stem.

when to use it

Causative + passive: use this combination when you want to express that someone was made to do something, but you do not name — or do not want to name — the person who gave the order. The passive removes the causer from subject position.
Reciprocal + causative: use this when a subject causes two or more parties to perform a mutual action — for example, making two people meet, talk, or kiss each other.
Double causative: use this when the subject does not cause the action directly but instead causes a second person to cause a third person to act. The second causative suffix is -t- (not a repetition of -dir-), giving forms such as yaptır-t- or yazdır-t-.

formation

The permitted stacking order is shown below. Each arrow means «may be followed by».

STEM → [reflexive | reciprocal] → causative → [causative] → passive

Every bracket above marks an optional slot. The only hard rule is that nothing except a second passive may follow a passive suffix.

The table below shows the three most common combined-voice patterns with a concrete example for each.

pattern	example form	meaning
reciprocal + causative	görüş-tür-	make (them) meet / put in touch
causative + passive	yaptır-ıl-	be made to do
causative + causative (double)	yazdır-t-	have someone make (another) write

The second causative suffix is always -t-, not a second -dir-. yaptırdır- is not a standard Turkish form; the correct double causative is yaptırt-.

examples in context

Bütün öğrencilere resim yaptırıldı.

All the students were made to draw.

yap- + -tır- (causative) + -ıl- (passive). The causer is not named; the passive removes them from subject position.

Baba çocukları öpüştürdü.

The father made the children kiss each other.

öp- + -üş- (reciprocal) + -tür- (causative). The reciprocal establishes the mutual action; the causative adds an external agent.

Onları görüştürdü.

She put them in touch / made them meet.

gör- + -üş- (reciprocal) + -tür- (causative). A compact way to express arranging a meeting between two parties.

Mektubu bana yazdırttı.

He had someone make me write the letter.

yaz- + -dır- (causative) + -t- (second causative). The subject caused an intermediary, who in turn caused me to write.

common pitfalls

Wrong stacking order: placing a causative suffix after a passive, or a reciprocal after a causative, produces an ill-formed verb. The order is fixed: reciprocal/reflexive → causative → passive. A form like *yaptırıldır- (passive then causative) is not grammatical.
Adding a non-passive suffix onto a passive stem: once a passive suffix is present, the only suffix that may follow is a second passive (rare but attested, e.g. sevilindi). Attempting to attach a causative or reciprocal suffix after a passive is not permitted.
Wrong second-causative allomorph: the double causative uses -t- as its second suffix, not a repeated -dir-. Writing *yaptırdır- instead of yaptırt- is a very common error. Always use the short -t- for the second causative slot.
