To talk about beginnings and endings in Turkish you need three verbs and two grammar facts that English never prepares you for. başlamak (to start) does not take a direct object — it takes the dative case, and getting this wrong is one of the most common case errors learners make. bitirmek (to finish, transitive) and bitmek (to end, intransitive) are a paired set: one needs a doer with an object, the other describes something ending on its own. Master these and you can frame almost any activity from its first moment to its last.
başlamak — start, but with the dative
The stem is başla- (vowel-final). The headline rule: başlamak governs the dative case -A (-e / -a), never the accusative. Where English says “start the project”, Turkish says “start to the project” — you start toward an activity. This is unintuitive for English and even for Spanish speakers, so it deserves real attention.
| Form | başlamak |
|---|---|
| present continuous (o) | başlıyor |
| aorist (o) | başlar |
| past (o) | başladı |
| future (o) | başlayacak |
| negative continuous (o) | başlamıyor |
| question (o) | başlıyor mu? |
With a noun, that noun goes into the dative: işe başladım (I started work), okula başladı (he started school), yeni bir projeye başlıyoruz (we're starting a new project). The dative ending harmonises and inserts a buffer -y- after vowel-final nouns: proje → projeye, iş → işe.
Bugün yeni işe başladım, çok heyecanlıyım.
I started my new job today, I'm very excited.
Küçük oğlum bu yıl okula başlıyor.
My little son is starting school this year.
Pazartesi günü yeni bir projeye başlayacağım.
On Monday I'll start a new project.
To say start doing something, you put the verb into the dative verbal noun -mAyA (the -mAk infinitive in the dative): okumaya başladım (I started reading), yağmur yağmaya başladı (it started to rain). This -mAyA başlamak pattern is everywhere and is the natural Turkish way to express “began to…”.
Sınav yaklaşınca herkes ciddi ciddi çalışmaya başladı.
As the exam got closer, everyone seriously started studying.
Hava kararmaya başladı, artık eve dönsek iyi olur.
It's starting to get dark, we'd better head home now.
bitirmek — finish (transitive, takes the accusative)
The stem is bitir- (consonant-final). bitirmek is the transitive verb: someone finishes something, so it needs a doer and a direct object, and that object takes the accusative when definite: ödevi bitirdim (I finished the homework), kitabı bitirdi (she finished the book).
| Form | bitirmek |
|---|---|
| present continuous (o) | bitiriyor |
| aorist (o) | bitirir |
| past (o) | bitirdi |
| future (o) | bitirecek |
| negative continuous (o) | bitirmiyor |
| question (o) | bitiriyor mu? |
Raporu bu akşam bitiririm, merak etme.
I'll finish the report this evening, don't worry.
Yemeğini bitirmeden masadan kalkma.
Don't get up from the table before you finish your food.
bitirmek also means to graduate from a school — liseyi bitirdim (I finished/graduated high school) — and even to exhaust a supply: şekeri bitirmişiz (we've used up all the sugar).
Üniversiteyi geçen yıl bitirdim, şimdi iş arıyorum.
I graduated from university last year, now I'm looking for work.
bitmek — end, run out (intransitive, no object)
The stem is bit- (consonant-final). bitmek is the intransitive twin: something ends, runs out, or is over by itself, with no doer mentioned. The subject is the thing that ends — iş bitti (the work is done), film bitti (the film is over), benzin bitti (the petrol ran out). It takes no object at all.
| Form | bitmek |
|---|---|
| present continuous (o) | bitiyor |
| aorist (o) | biter |
| past (o) | bitti |
| future (o) | bitecek |
| negative continuous (o) | bitmiyor |
| question (o) | bitti mi? |
Toplantı daha yeni bitti, çıkıyorum.
The meeting just ended, I'm leaving now.
Sütümüz bitmiş, markete uğramam lazım.
We're out of milk, I need to stop by the shop.
The link between the two is causative morphology: bitirmek is literally bitmek + the causative -İr — to cause to end = to finish. This is the same machinery that builds many transitive verbs in Turkish from intransitive roots, and recognising the pattern (bit- → bitir-) helps you predict pairs like piş- / pişir- (to cook). The choice between the pair is purely about whether there's a doer acting on an object: doer + object → bitirmek; no doer, the thing ends on its own → bitmek.
Pilim bitmek üzere, birazdan kapanır.
My battery's about to die, it'll shut off any moment.
Sonunda tezimi bitirdim ve tez bitince büyük bir rahatlama hissettim.
I finally finished my thesis, and when the thesis was done I felt enormous relief.
That last sentence shows both verbs side by side: I finished the thesis (bitirdim, transitive), and the thesis being done (bitince, from intransitive bitmek).
Common mistakes
❌ Bugün işi başladım.
Wrong case — başlamak takes the dative, so it must be işe, not işi.
✅ Bugün işe başladım.
I started work today.
❌ Yeni projeyi başlıyoruz.
Wrong case again — başlamak demands the dative projeye.
✅ Yeni projeye başlıyoruz.
We're starting a new project.
❌ Okumaya bitirdim.
Wrong — bitirmek takes a noun object in the accusative, not -mAyA; use the verbal noun -mAyI: okumayı bitirdim.
✅ Okumayı bitirdim.
I finished reading.
❌ Filmi bitti, eve gidelim.
Wrong verb/marking — the film ends by itself, so use intransitive bitmek with the film as plain subject: film bitti.
✅ Film bitti, eve gidelim.
The film's over, let's go home.
❌ İşimi bitti, çıkabilirim.
Wrong — if you mean 'my work is done' use bitmek (işim bitti); bitirmek would need 'işimi bitirdim' (I finished my work).
✅ İşim bitti, çıkabilirim.
My work is done, I can leave.
Key takeaways
- başlamak takes the dative: işe başladım, okula başladı, projeye başlıyoruz — never the accusative.
- To say start doing, use -mAyA başlamak: okumaya başladım, yağmaya başladı.
- bitirmek is transitive (accusative object): ödevi bitirdim; it also means to graduate from and to use up.
- bitmek is intransitive (no object): iş bitti, benzin bitti.
- bitirmek = bitmek + causative -İr — the doer-versus-no-doer test tells you which to pick.
