What Does Olsun Mean in Turkish? The -sın Ending Behind Everyday Wishes

For readers in a hurry: Olsun means "may it be." It is ol- (to be) plus the ending -sın / -sin / -sun / -sün, the third-person form of the Turkish imperative and the same ending sits inside kolay gelsin, geçmiş olsun, afiyet olsun and hayırlı olsun. Once you can see it, a list of phrases you memorized one by one becomes a single pattern and the same pattern will be waiting for you in a café, where the waiter uses it to bring your tea. Read on for how it works and where it stops working.

Spend an ordinary day in Türkiye with your ears open and the same small ending keeps coming back. A man carrying boxes up the stairs hears kolay gelsin from a neighbor. Someone back from the dentist hears geçmiş olsun. A plate lands on the table with afiyet olsun, and a friend holding the keys to a new flat waits for you to say hayırlı olsun.

A phrasebook lists these as four separate entries, each with its own translation. All four end in a verb carrying the same suffix.

The ending itself

Take a verb stem and add -sIn. Grammar books write it with a capital I because its vowel follows four-way vowel harmony, the same way the accusative ending does:

kal → kalsın (let it stay)

gel → gelsin (let it come)

ol → olsun (let it be)

gör → görsün (let him or her see)

The last vowel of the stem decides the form. After a or ı you get -sın, after e or i -sin, after o or u -sun, and after ö or ü -sün.

Turkish school grammar files this under emir kipi, the imperative, as its third-person form. Gerjan van Schaaik's Oxford Turkish Grammar gives it a chapter of its own under the name indirect imperative. Gel! is addressed to the person in front of you.

Gelsin points past the listener, toward someone or something else: let him come, have her come, may it come.

The form also does everyday work. In a tea garden you can order with İki çay gelsin, literally "let two teas come." A manager can say Ayşe Hanım gelsin and mean "send Ayşe Hanım in." A host can ask Çay gelsin mi?, offering to have tea brought.

When the "someone or something else" is a task, an illness or a meal, the same request becomes a wish. Kolay gelsin wishes that the work in front of someone comes easily. The cultural side of that phrase, and who says it to whom, is in The Quiet Ethics of Turkish: Understanding Kolay Gelsin.

Why olsun turns up everywhere

Olsun is ol-, the stem of olmak (to be, to become), plus the same ending: ol + sun. If olmak still feels slippery, the post on how "to be" works in Turkish covers it. As a wish, olsun means "may it be," and Turkish can place a noun, an adjective or a whole phrase in front of it.

Afiyet olsun – may it be with good health; said over food. (more on afiyet olsun)

Hayırlı olsun – may it be auspicious; for a new home, a new job, a new car.

Geçmiş olsun – may it be in the past; for an illness, an accident, a hard week. Geçmiş is the participle of geçmek, "to pass." (more on geçmiş olsun)

Sıhhatler olsun – may it bring good health; a traditional wish after a haircut or a bath. Yolun açık olsun – may your road be open; before a trip or a new undertaking.

Allah razı olsun – may God be pleased with you; a deep thank-you.

Başın sağ olsun belongs on this list too, with a warning attached. Literally "may your head be sound," it is said only to someone who has lost a person close to them. The grammar is identical to afiyet olsun, and the two sentences belong to completely different days. The usual reply is Dostlar sağ olsun, "may friends be well," which is one more olsun. The customs around the phrase are in Başın Sağ Olsun: What Turkish Holds in a House of Mourning.

Olsun can also stand alone. Said on its own, it keeps its literal sense, "let it be," and works like English "never mind" or "that's fine": someone says Geç kaldım ("I'm late") and the answer is Olsun, otur ("Never mind, sit down").

The same ending on other verbs

Olsun gets most of the attention, but any verb can take the ending:

Günün güzel geçsin. – May your day pass well. (Have a nice day.)

Allah şifa versin. – May God give healing.

Allah göstermesin. – May God not show it. (God forbid.)

Nazar değmesin. – May the evil eye not touch it.

The last two are negative. The negative suffix -mA comes between the stem and the ending: değ + me + sin → değmesin, ol + ma + sın → olmasın. After an apology you may hear Bir daha olmasın, "let it not happen again," usually a mild warning that also ends the subject.

When the wish is addressed to God, the third person is built into the sentence, because Allah is the subject: Allah gives; Allah does not show.

Blessing someone who isn't there

The third-person form also lets you bless someone who is absent. Compare the forms of the same verb:

Sağ ol. – thanks (to one person; literally "be well")

Sağ olun. – thanks (polite or plural)

Sağ olsun. – bless him or her (about someone else)

Sağ olsunlar. – bless them

Komşumuz sağ olsun, kapıyı açtı means "Our neighbor, bless him, opened the door for us." You are thanking a person who is not there to hear it. Sağ olsunlar, çok yardım ettiler does the same for a whole group. In the same way, Annen çabuk iyileşsin wishes a quick recovery to your friend's mother, who is not in the conversation.

Making your own wishes

The pattern is productive, so you can build wishes nobody taught you:

Sınavın iyi geçsin. – May your exam go well.

Yolculuğun rahat geçsin. – May your trip be comfortable.

Her şey gönlünce olsun. – May everything be as you wish.

Hafta sonun güzel geçsin. – Have a nice weekend.

A wish can be grammatically perfect and still sound odd, because the fixed formulas come attached to their situations and a translation will not tell you which situation that is. A 2009 study in the Canadian Journal of Applied Linguistics compared 23 common Turkish good-wish formulas with their French counterparts and found a perfect match for only one of them.

Where the pattern stops

Several everyday Turkish wishes use other structures, and they are easier to remember once you can name them.

Eline sağlık is a noun phrase with no verb at all: el (hand) + -ine + sağlık (health), "health to your hand," said to someone who has cooked or made something. The cook usually answers with afiyet olsun, so the exchange ends on an olsun after all.

Güle güle kullan is a second-person imperative: "use it laughing," said to someone with a new purchase.

İyi şanslar and başarılar are plural nouns, "good lucks" and "successes."

Keşke gelse expresses a different kind of wish, a longing for something that is not happening. It uses the conditional -sa / -se and means "if only he would come."

Then there is the sneeze. Çok yaşa, "live long," is a second-person imperative too, aimed straight at the person who sneezed, and the reply turns it around: Sen de gör, "may you see it too."

Frequently Asked Questions (FAQ)

Q: What does olsun mean in Turkish?

A: Olsun means "may it be" or "let it be." It is ol-, the stem of olmak (to be), plus the third-person imperative ending -sun, and it appears in many everyday wishes such as afiyet olsun and geçmiş olsun. On its own, olsun can also mean "never mind" or "that's fine."

Q: What does -sin mean in Turkish?

A: In forms like gelsin and olsun, -sin is the third-person imperative ending, written -sIn in grammar books because its vowel changes with vowel harmony (-sın, -sin, -sun, -sün). It can mean "let him / her / it…" or, in wishes, "may…".

Q: Why is it olsun and not olsin?

A: The ending follows four-way vowel harmony. The stem ol- has the vowel o, so the suffix becomes -sun.

Q: What is the difference between gelsin and keşke gelse?

A: Gelsin presents his coming as something requested or wished for: let him come, may it come. Keşke gelse uses the conditional and expresses longing about something that is not happening: if only he would come.

Q: Can I invent my own wishes with -sin?

A: Yes. Sınavın iyi geçsin and günün güzel geçsin are natural Turkish. Fixed formulas such as başın sağ olsun belong to specific situations, so learn those together with the moment they are used.
