Expressing the Subjunctive | Turkish Grammar

Speakers of Romance languages spend years drilling the subjunctive; English keeps faint traces of it ("I suggest that he go," "if I were you," "lest it be lost"). When such learners come to Turkish they instinctively hunt for "the Turkish subjunctive" — and find nothing, because Turkish has no dedicated subjunctive mood at all. Instead, the work the subjunctive does in other languages — expressing wishes, suggestions, hypotheticals, purposes, and things that are wanted rather than real — is split across three separate devices: the optative -(y)A, the conditional -sA, and -mA nominalizations. Once you know which device covers which slice of "irrealis," the whole apparent gap closes.

Why there is no one-to-one form

The English subjunctive bundles together meanings Turkish keeps apart. "That he go" (a wished-for action), "were I to go" (a hypothetical), "so that he might go" (a purpose) — English shoehorns all three into one bare verb form. Turkish, being agglutinative and explicit, gives each its own marker. The lesson is to stop translating the form and start translating the meaning: identify whether you mean a wish, a condition, or an embedded want/suggestion, then pick the matching tool.

Önemli olan gelmen, gerisi önemli değil.

What matters is that you come; the rest doesn't matter.

Here English uses a subjunctive-flavoured "that you come"; Turkish uses the -mA verbal noun with a possessive — gel- + -me- + -n = gelmen, literally "your coming." The wished-for action becomes a noun.

The optative -(y)A: wishes, "let," and "may"

The optative suffix -(y)A expresses a wish or a softly proposed action — "let me," "let's," "may he," "let him." Its first-person forms are everyday (gideyim "let me go," gidelim "let's go"), while the third person (gide / commonly gitsin with the imperative) carries "may he / let him."

Hadi artık gidelim, geç oluyor.

Come on, let's go now; it's getting late.

Allah yardımcın olsun, işin kolay olsun.

May God help you; may your task be easy.

The third-person optative most often surfaces as the -sIn imperative ("let him/her/it…") and pairs with diye to express purpose — "so that," "lest." This is how Turkish renders the English subjunctive of purpose and the archaic "lest."

Korkmasın diye elini sıkıca tuttum.

I held her hand tightly so that she wouldn't be afraid. (lit. saying “let her not fear”)

Çocuklar duymasın diye fısıldadılar.

They whispered so the children wouldn't hear. (lest the children hear)

💡

When English says “so that he might…,” “in order that…,” or the old-fashioned “lest…,” reach for the third-person optative/imperative -sIn plus diye: gelsin diye, unutmasın diye. This single pattern covers a whole family of English subjunctive-of-purpose sentences.

The conditional -sA: hypotheticals and "were I to"

The English subjunctive of unreality — "if I were," "were I to go," "if only" — maps onto the Turkish conditional -sA. For an open future condition it pairs with eğer; for a counterfactual or wish it stacks with the past to make -sAydI ("if … had"), and standing alone it expresses "if only / I wish."

Gitse iyi olur, burada kalmasının anlamı yok.

It would be good if he went; there's no point in his staying here.

Keşke biraz daha sabırlı olsam.

If only I were a bit more patient.

Yerinde olsam, o işi kabul etmezdim.

If I were in your place, I wouldn't take that job.

Note olsam ("were I") doing precisely the work of the English subjunctive "were I." Turkish does not have a special "were" — the conditional suffix carries the whole counterfactual load.

The -mA nominalization: "that he leave," suggestions and wants

This is the device English speakers most often miss. When English uses a subjunctive complement after verbs of wanting, suggesting, requesting, ordering, or preventing — "I want that he come," "I suggest that he leave," "I insist that she be here" — Turkish turns the inner verb into a -mA verbal noun, adds the subject's possessive, and puts it in the case the main verb requires (usually accusative -(s)I(n)I).

Gitmesini istiyorum, burada işi kalmadı.

I want him to leave; he has nothing left to do here.

Erken gelmemizi öneriyor, trafik yüzünden.

He suggests that we come early, because of the traffic.

Doktor, bol su içmesini tavsiye etti.

The doctor advised her to drink plenty of water.

Dissect gitmesini: git- (go) + -me- (verbal noun) + -si- (3sg possessive "his going") + -ni (accusative). The whole subordinate clause "that he leave" becomes one accusative noun, "his leaving," handed to istiyorum. There is no word for "that," no separate subjunctive verb — the nominalizer does everything. English's "I suggest that he leave" is, structurally, Turkish's "I suggest his leaving."

Öğretmen, herkesin sessiz olmasını istedi.

The teacher wanted everyone to be quiet. (insisted that everyone be quiet)

💡

Whenever an English subjunctive sits after want / suggest / advise / insist / prevent (“that he go,” “that she be”), don't look for a verb form — nominalize it: -mA + possessive + the case the main verb needs. “I suggest that he leave” becomes gitmesini öneriyorum, literally “I suggest his leaving.”

Choosing the right tool

English subjunctive meaning	Turkish device	Example
wish / "let" / "may"	optative -(y)A, -sIn	gidelim; iyi olsun
purpose / "so that" / "lest"	-sIn + diye	korkmasın diye
hypothetical / "were I to" / "if only"	conditional -sA(ydI)	gitse; keşke olsam
"that he leave" after want/suggest	-mA + possessive (+ case)	gitmesini istiyorum

Common mistakes

❌ Gitmek istiyorum onu.

Incorrect — using the bare infinitive when the subject of going differs from the wanter; you need a -mA nominalization.

✅ Gitmesini istiyorum.

I want him to leave. (different subjects → -mAsInI)

When the two subjects are the same ("I want to go"), the plain infinitive is right: Gitmek istiyorum. The -mA nominalization is required only when the subjects differ.

❌ Öneriyorum ki o gitsin (ki-cümlesiyle çeviri zorlaması).

Stylistically marked — calquing English “that” with ki; Turkish prefers the -mA nominalization.

✅ Gitmesini öneriyorum.

I suggest that he leave.

❌ Eğer ben sen olurum, kabul etmem.

Incorrect — a counterfactual needs the conditional -sA, not the aorist olurum.

✅ Yerinde olsam, kabul etmezdim.

If I were you, I wouldn't accept.

❌ Duymalar diye fısıldadılar.

Incorrect — purpose “so that they not hear” uses the third-person -sIn imperative plus diye.

✅ Duymasınlar diye fısıldadılar.

They whispered so that they wouldn't hear.

Key takeaways

Turkish has no dedicated subjunctive. Irrealis is split across three devices; translate the meaning, not the English form.
Optative -(y)A / -sIn = wishes, "let," "may"; with diye it builds purpose and "lest."
Conditional -sA(ydI) = hypotheticals, "were I to," "if only," counterfactuals.
-mA + possessive (+ case) = the complement subjunctive ("that he leave / be / go") after want, suggest, advise, insist, prevent.
Use the plain infinitive only when subjects match (gitmek istiyorum); switch to -mAsInI the moment the subjects differ (gitmesini istiyorum). And resist calquing "that" with ki.
