Conditional Mood in Turkish

In Brief

Turkish usually marks an “if” clause with -se/-sa, following vowel harmony: Gelirsen sevinirim means “If you come, I’ll be happy.” The suffix can follow a verb stem or a tense form, while ise and its attached forms -(y)se/-(y)sa add “if” to nouns, adjectives, and other predicates: Hazırsan başlayalım (“If you’re ready, let’s begin”).

Overview

The Turkish conditional, called koşul kipi, lets one situation depend on another. In Vaktin varsa kahve içelim (“If you have time, let’s have coffee”), having time is the condition and drinking coffee is the proposed result. At B1, this pattern is essential for plans, warnings, offers, choices, and polite suggestions.

English normally puts the separate word if before a clause. Turkish often puts the same idea directly onto the predicate (the part that says what happens or what something is): gel-ir-se-n literally builds “come + aorist + if + you.” The word eğer also means “if,” but it is optional because the suffix already marks the condition.

The form of the result clause is not fixed. It can state a likely result, give an instruction, make a suggestion, or describe what would happen in an imagined situation. This article begins with productive B1 patterns, then separates more complex unreal and past conditions into the advanced section.

How It Works

Choosing between -se and -sa

The suffix follows two-way vowel harmony: its vowel matches the last vowel before it.

Last vowel	Conditional suffix	Example	Meaning
e, i, ö, ü	-se	gelirse	if he/she comes
a, ı, o, u	-sa	bakarsa	if he/she looks

The consonant remains s; it does not change to z or another consonant.

Personal endings

When -se/-sa is attached directly to a verb stem, personal endings show who the subject is. Here is the full pattern with gelmek (“to come”):

Person	Form	English
ben	gelsem	if I came / if I were to come
sen	gelsen	if you came
o	gelse	if he/she/it came
biz	gelsek	if we came
siz	gelseniz	if you came (plural or polite)
onlar	gelseler	if they came

Turkish frequently omits subject pronouns because these endings already identify the subject: Gelsen konuşuruz is naturally “If you come, we’ll talk.”

The direct stem + conditional pattern often presents a situation as imagined, tentative, wished for, or proposed. For an open, realistic future condition, Turkish very commonly puts -se/-sa after the aorist (the general-present form):

Build	Result	Typical meaning
gel- + -ir + -se + -n	gelirsen	if you come / if you do come
iste- + -r + -se + -n	istersen	if you want
ol- + -ur + -sa	olursa	if it happens / if there is
çalış- + -maz + -sa + -n	çalışmazsan	if you do not work

This dependence on the aorist is why knowing Turkish Aorist (General Present) first is useful.

Conditions with tense forms

The conditional can follow other tense or aspect forms (forms that locate or shape an action in time). Common combinations include:

Pattern	Example	Usual idea
aorist + conditional	gelirse	if he/she comes
progressive + conditional	geliyorsa	if he/she is coming
definite past + conditional	geldiyse	if he/she came / if it is true that they came
reported past + conditional	gelmişse	if he/she has apparently come / if they have come
future + conditional	gelecekse	if he/she is going to come

When the preceding form ends in a vowel, a buffer y appears: geldi-y-se, hasta-y-sa. Treat the whole sequence as one word in standard writing.

Negative conditions

Negation comes before the conditional marker:

• gelirsen — if you come
• gelmezsen — if you do not come
• geliyorsan — if you are coming
• gelmiyorsan — if you are not coming
• gelsen — if you came / if you were to come
• gelmesen — if you did not come; also “how about not coming?” in an appropriate context

Notice the important contrast between -mez/-maz in an aorist condition and -me/-ma before a direct conditional form.

Nouns, adjectives, and locations: ise and -(y)se/-(y)sa

A Turkish sentence does not need a word meaning “be” in the present tense: Hazırsın means “You are ready.” To make this conditional, use ise or its attached form. A buffer y is used after a vowel.

Plain statement	Conditional	English
Hazırsın.	Hazırsan...	If you are ready...
Öğrencisin.	Öğrenciysen...	If you are a student...
Evde.	Evdeyse...	If he/she is at home...
Sorun değil.	Sorun değilse...	If it is not a problem...
Bu senin.	Bu seninse...	If this is yours...

The separate form can carry contrastive emphasis: Hava güzel ise yürüyelim. The attached form is very common and neutral: Hava güzelse yürüyelim. In careful writing, attached conditional forms are written as part of the preceding word.

The result clause

A conditional clause can combine with several kinds of result:

Function	Condition	Result	Whole meaning
likely consequence	Gelirsen	sevinirim.	If you come, I’ll be happy.
suggestion	İstersen	gidelim.	If you want, let’s go.
instruction	Bitirirsen	bana gönder.	If you finish it, send it to me.
permission/option	Yorgunsan	dinlenebilirsin.	If you’re tired, you can rest.
hypothetical result	Param olsa	alırdım.	If I had money, I would buy it.

Unlike the traditional English rule that often discourages will inside an if-clause, Turkish chooses a form according to meaning rather than copying English tense patterns word for word. Learn the Turkish condition and result as a pair.

Examples in Context

Turkish	English	Note
Gelirsen sevinirim.	If you come, I’ll be happy.	Open, realistic condition
İstersen gidelim.	If you want, let’s go.	Gentle suggestion
Vaktin varsa beni ara.	If you have time, call me.	Condition + instruction
Yağmur yağarsa evde kalacağız.	If it rains, we’ll stay home.	Future consequence
Erken çıkmazsak otobüsü kaçırırız.	If we don’t leave early, we’ll miss the bus.	Negative condition
Hazırsanız toplantıya başlayalım.	If you’re ready, let’s start the meeting.	Polite or plural “you”
Kafede yer yoksa başka bir yere gideriz.	If there’s no room at the café, we’ll go somewhere else.	Noun predicate + yoksa
Ali evdeyse ona da haber ver.	If Ali is at home, let him know too.	Location predicate
Bu akşam çalışıyorsan seni rahatsız etmeyeyim.	If you’re working this evening, I won’t disturb you.	Progressive condition
Paket geldiyse masanın üstüne bırak.	If the package arrived, leave it on the table.	Past fact to be checked
Yarın gelecekse bugün hazırlık yapalım.	If he/she is going to come tomorrow, let’s prepare today.	Future plan as condition
Öğrenciysen indirim alabilirsin.	If you’re a student, you can get a discount.	Noun predicate
Ben olsam bu teklifi kabul etmezdim.	If I were you, I wouldn’t accept this offer.	Advice through a hypothetical
Param olsa alırdım.	If I had money, I would buy it.	Present unreal condition

The condition can come second without changing the basic relationship: Beni ara, vaktin varsa. A comma is especially useful when the condition comes first and the clauses are long, though punctuation varies in short sentences.

Common Mistakes

Adding eğer but forgetting the suffix

• Wrong: Eğer vaktin var, beni ara.
• Right: Eğer vaktin varsa beni ara.
• Also right: Vaktin varsa beni ara.
• Why: Eğer can highlight the condition, but it does not normally replace the conditional marking on the predicate.

Using the wrong harmony vowel

• Wrong: Gelirsan beni ara.
• Right: Gelirsen beni ara.
• Why: The last vowel in gelir- is i, so the front-vowel form -se is required.

Leaving out the personal ending

• Wrong: Sen gelir-se sevinirim.
• Right: Sen gelirsen sevinirim.
• Why: The conditional predicate still agrees with its subject. For sen, add -n after -se/-sa.

Copying English tense choices directly

• Wrong strategy: choosing every Turkish form by matching “if + present” or “would” mechanically.
• Right: Gelirsen konuşuruz for a real possibility; Gelsen konuşurduk for a more remote imagined one.
• Why: Turkish builds these contrasts through its own tense and conditional combinations. The English translation may hide distinctions that Turkish makes explicitly.

Putting negation after the conditional

• Wrong: gelirseme or gelirsen değil
• Right: gelmezsen (“if you don’t come”) or, with a different nuance, gelmesen
• Why: The negative marker belongs before the conditional suffix.

Separating an attached form incorrectly

• Wrong: hazır san; öğrenci ysen
• Right: hazırsan; öğrenciysen
• Why: The attached conditional and its buffer consonant are written with the word they follow.

Usage Notes

Eğer is optional. Use it to announce or emphasize a condition, especially when the sentence is long or when alternatives are being contrasted. In everyday speech, the suffix alone is often enough: Müsaitsen konuşalım.

İstersen is a conversational softener. Literally “if you want,” it makes suggestions less forceful: İstersen sonra konuşuruz (“We can talk later if you like”). Mümkünse (“if possible”) and sakıncası yoksa (“if you don’t mind”) similarly soften requests.

Yoksa has two common jobs. As a conditional form of yok, it can mean “if there isn’t/aren’t”: Ekmek yoksa alalım. As a separate connector, it can mean “or else” or introduce an alternative question: Acele et, yoksa geç kalacağız (“Hurry, or else we’ll be late”). Context distinguishes them.

Clause order is flexible. The condition usually comes first when it sets the scene, but speakers may add it afterward as a qualification: Yarın buluşalım, uygunsan (“Let’s meet tomorrow, if that works for you”). Turkish word order is flexible, but keeping the condition and its predicate together makes the sentence easier to follow.

Beyond the Basics: Unreal, Past, and Elliptical Conditions

A direct stem + -se/-sa form can move beyond a neutral future condition. With an aorist result in the past form -dı/-di, it commonly creates a present hypothetical:

• Daha çok zamanım olsa Türkçe çalışırdım. — If I had more time, I would study Turkish.
• Senin yerinde olsam müdürle konuşurdum. — If I were in your position, I would talk to the manager.

Here, olsa does not say that the condition is true. The result çalışırdım/konuşurdum describes what would happen in that imagined situation. This is the foundation for more complex conditionals.

For conditions contrary to a past fact, Turkish uses forms such as -seydi/-saydı:

• Daha erken çıksaydık treni kaçırmazdık. — If we had left earlier, we would not have missed the train.
• Bana söyleseydin yardım ederdim. — If you had told me, I would have helped.

These forms combine the conditional with past marking and belong to the next stage of study. More elaborate result forms are also possible: Çalışsaydın kazanmış olurdun (“If you had worked, you would have won”). Study their time relationships systematically under Complex Conditionals.

Conditional forms also appear without a fully stated result. The listener supplies it from context:

• Biraz beklesen? — What if you waited a little? / Could you wait a little?
• Keşke burada olsa. — If only he/she were here.
• Ya gelmezse? — What if he/she doesn’t come?

These are not all ordinary “if X, then Y” sentences. Intonation and words such as keşke (“if only”) or ya (“what if”) turn the conditional into a suggestion, wish, worry, or tentative request. Wishes deserve separate attention because their meaning depends strongly on time and context.

Finally, ise can mark contrast rather than a literal condition, especially after a topic: Ayşe çay içti, Mehmet ise kahve içti (“Ayşe drank tea, whereas Mehmet drank coffee”). In this use, translating it as “if” would be wrong. Recognizing this contrastive ise prevents confusion in formal writing and narratives.

Practice Tips

1. Build four versions of one situation. Start with gelmek: gelirsen, gelmezsen, geliyorsan, geldiysen. Say what each condition means and add a natural result clause.
2. Practise predicate types, not just verbs. Make conditions from an adjective (yorgunsan), a noun (öğrenciysen), and a location (evdeysen). This makes -(y)se/-(y)sa automatic.
3. Listen for complete pairs. When you hear istersen, varsa, olursa, or değilse, note both the condition and what follows. Then retell the sentence with and without eğer.

• Prerequisite: Aorist (General Present) — supplies forms such as gelir, ister, and olur before the conditional suffix.
• Next step: Wishes and Desires — develops uses with keşke and wish meanings such as gelseydi.
