Aspect: How Turkish Slices Time | Turkish Grammar

Aspect is about the internal shape of an event — whether you view it as ongoing, completed, habitual, sudden, or repeated — as opposed to tense, which locates it in time. English packs much of its aspect into a handful of forms (the progressive be …-ing, the perfect have …-en). Turkish does something subtler: it spreads aspect across the whole grammar. Some of it lives inside the tense suffixes, some in auxiliary verbs, some in special compound verbs, and some in converbs. The single most useful idea on this page is that you cannot map each English aspect to one Turkish "tense" — you have to learn which device carries which shade.

Aspect lives inside the tenses: -(I)yor vs -Ir

The clearest case is the pair every learner meets early: the present continuous -(I)yor and the aorist -Ir. English speakers are taught these as "present progressive" and "simple present," but the real difference between them is aspectual, not temporal. Both can refer to the present, yet they view the event differently.

-(I)yor is imperfective/progressive: the action is in progress, viewed from inside, happening right now or around now.

Şu an kitap okuyorum, sonra ararım.

I'm reading a book right now; I'll call you later.

-Ir (the aorist) is habitual/generic: it states what generally, typically, or characteristically happens — a property of the world, not an event unfolding before you.

Her sabah çay içerim, kahveyi sevmem.

I drink tea every morning; I don't like coffee.

Put them side by side and the aspectual contrast is unmistakable: okuyorum = "I'm in the middle of reading"; okurum = "I read (as a habit / I'm a reader)." Choosing -(I)yor when you mean a habit, or -Ir when you mean right-now, is one of the most common ways learners sound subtly off.

Genelde otobüse binerim ama bugün taksiye biniyorum.

I usually take the bus, but today I'm taking a taxi.

💡

The -(I)yor / -Ir choice is not "now vs later" — it's "in progress vs characteristic." If you can insert “right now,” use -(I)yor; if you can insert “generally / as a rule,” use -Ir. This single test resolves most of the confusion.

Perfect and resultative: -mIş olmak

To say that an event is completed with a result still relevant — the perfect — Turkish uses the compound -mIş olmak ("to have done / to be in the state of having done"). This is a genuine aspectual auxiliary: olmak ("to be/become") carries the tense, while the -mIş participle supplies the completed-event meaning. It is how you say "by then I will have finished," "I had already eaten," and so on.

Sen gelene kadar yemeği bitirmiş olurum.

I'll have finished the meal by the time you arrive.

O konuştuğunda ben çoktan kararımı vermiş olacaktım.

By the time he spoke, I would already have made my decision.

Note that this -mIş is the participle/perfect -mIş, distinct from the evidential narrative -mIş. The auxiliary olmak is what makes it a perfect rather than a hearsay statement: gitmiş alone can mean "apparently he went," but gitmiş ol- unambiguously means "to have gone."

💡

When you reach for an English perfect (“have done,” “had done,” “will have done”), don't try to find a single Turkish tense — build it: the participle -mIş plus olmak, with olmak carrying whatever tense you need. The aspect (completion) and the tense (when) are supplied by two different pieces.

Lexical aspect: the -(y)Iver and -(y)Adur compounds

Turkish also bolts aspect directly onto a verb stem with auxiliary compound verbs, where a converb in -(y)I or -(y)A fuses with a light verb. The most common is -(y)Iver-, which adds a sense of suddenness, ease, or "just doing it quickly."

Şu pencereyi bir açıver, çok sıcak oldu.

Just pop that window open, would you — it's gotten so hot.

Markete kadar gidiverdim, beş dakika sürmedi.

I just nipped over to the shop; it didn't even take five minutes.

A rarer relative, -(y)Adur-, adds continuity ("keep on doing"), and -(y)Akal- ("be left doing / freeze"). These are lexical-aspect flavours fused to the verb rather than separate words — there is no neat English suffix for them, which is exactly why they are worth knowing.

Sen hazırlanadur, ben arabayı çıkarayım.

You keep getting ready; I'll bring the car out.

Backgrounding and iteration: the converbs -ken and -DIkçA

Converbs (adverbial verb forms) carry aspect at the level of clause relations. -ken ("while") sets up a background, ongoing event against which the main event happens — pure imperfective backgrounding. -DIkçA ("as / the more … the more / each time") expresses iteration or proportional repetition.

Eve dönerken yağmur başladı.

It started to rain while I was on my way home.

Onu tanıdıkça daha çok seviyorum.

The more I get to know her, the more I like her.

The formal written register has its own dedicated imperfective, -mAktA, which is a register-marked equivalent of -(I)yor used in news, science and officialese — covered on its own page.

A contrastive set: one stem, many aspects

To feel how the system distributes aspect, take the stem yaz- ("write") and watch the viewpoint change while the dictionary meaning stays put:

Form	Aspect	Meaning
yazıyor	imperfective / progressive	is writing (right now)
yazar	habitual / generic	writes (as a rule); is a writer
yazmış	evidential / resultative	has written (apparently / inferred)
yazıvermiş	sudden + evidential	apparently just dashed it off
yazmaktaydı	formal imperfective (past)	was (in the process of) writing

Mektubu yazıyor; her gün böyle uzun mektuplar yazar.

He's writing the letter; he writes long letters like this every day.

The tense — present, past, future — barely moves across this set; what shifts is how you look at the event. That is aspect, and Turkish hands you a different tool for each angle.

Common mistakes

❌ Her gün spor yapıyorum (alışkanlık kastederken).

Incorrect — using progressive -(I)yor for a stated habit.

✅ Her gün spor yaparım.

I exercise every day. (habitual aorist -Ir)

The reverse — using -Ir when something is in progress right now — is just as wrong: Şu an spor yaparım should be Şu an spor yapıyorum.

❌ Yemeği bitirdim olurum, sen gelince.

Incorrect — perfect needs the -mIş participle plus olmak, not -DI plus olmak.

✅ Sen gelince yemeği bitirmiş olurum.

I'll have finished the meal when you arrive.

❌ Pencereyi açıver yaptım.

Incorrect — -(y)Iver fuses to the stem (açıver-); you don't add a separate yapmak.

✅ Pencereyi açıverdim.

I just popped the window open.

❌ Eve döndüm yağmur başladı.

Incorrect — to express the ongoing background “while,” use the converb -ken, not two plain pasts.

✅ Eve dönerken yağmur başladı.

It started to rain while I was heading home.

Key takeaways

Aspect is distributed across Turkish grammar — inside tenses, in auxiliaries, in compound verbs, and in converbs. Don't expect one English aspect to map to one Turkish form.
The -(I)yor / -Ir contrast is aspectual: progressive (in progress) vs habitual (characteristic). Test with "right now" vs "generally."
-mIş olmak builds the perfect/resultative; the auxiliary olmak distinguishes it from evidential -mIş.
-(y)Iver / -(y)Adur / -(y)Akal fuse lexical aspect (suddenness, continuity, being-stuck) directly onto the stem.
Converbs -ken (backgrounding "while") and -DIkçA (iteration / "the more…") carry aspect at the clause level; -mAktA is the formal-register imperfective.
