The Turkish you meet in textbooks and the Turkish a twenty-year-old texts a friend are almost two different codes. Casual Turkish compresses words through predictable phonological shortcuts, leans on a productive slang lexicon, and pads almost every utterance with discourse particles. None of this is sloppiness — it is a coherent register with its own rules. You need to understand it to follow films, social media, and real conversation, but it is register-bound: deploying it in formal speech or writing is a serious mistake. This page teaches you to decode it, and warns you where the landmines are.
Systematic contractions
Casual speech reduces unstressed syllables in regular, predictable ways. These are non-standard transcriptions of pronunciation — you will see them in chat and subtitles, never in edited prose. The most common pattern collapses the present-continuous -(I)yorum ending: the final -um drops and -yor becomes -yo, giving -yom.
| Standard form | Colloquial reduction | Meaning |
|---|---|---|
| geliyorum | geliyom | I'm coming |
| gidiyorum | gidiyom | I'm going |
| ne yapıyorsun | napıyon | what are you doing |
| ne yapıyoruz | napıyoz | what are we doing |
| bir şey | bişey | something / anything |
| bir tane | bi tane | one (of them) |
| nasıl | nası | how |
Three reductions do most of the work. First, -(I)yorsun → -(I)yon (the -sun loses its -s and final consonant: yapıyorsun → yapıyon). Second, ne yap- → nap-, so ne yapıyorsun → napıyon in one move. Third, bir → bi before another word, and bir şey → bişey written solid.
Napıyon ya, akşam dışarı çıkıyo muyuz?
What are you up to — are we going out tonight? (napıyon = ne yapıyorsun; çıkıyo = çıkıyor; colloquial)
Bişey diyecektim ama unuttum, valla.
I was going to say something but I forgot, I swear. (bişey = bir şey; colloquial reduction)
Ben de geliyom, beni bekleyin bi dakika.
I'm coming too, wait for me a sec. (geliyom = geliyorum; bi = bir; colloquial)
The grammar underneath is unchanged — these are the same suffixes, just eroded in fast speech. If you mentally re-inflate geliyom → geliyorum, napıyon → ne yapıyorsun, the sentence parses normally.
Slang lexicon — with a caveat
Casual Turkish has a rich slang vocabulary (argo). Some of it is harmless and affectionate; some of it is rough and risky. You should recognize all of it, but be very careful about using it, because the same word can be friendly among close friends and offensive to a stranger.
- lan / ulan — a rough vocative particle tacked onto an address or exclamation, roughly "man / hey". Among close friends it reads as casual emphasis; toward a stranger, an elder, or in any formal setting it is confrontational and rude. Treat it as recognition-only until you have a very good ear for the relationship.
- kanka (also kankam) — "buddy, close friend", from kan kardeşi "blood brother". Warm and very common among young people; still firmly informal.
- acayip — literally "strange", used colloquially as an intensifier "really / insanely / wildly" (≈ çok but punchier).
- baya(ğı) — "quite, pretty, a fair bit", a softer informal intensifier.
Kanka bu dizi acayip iyiymiş, bir bölüm daha izleyelim mi?
Buddy, this series is insanely good — shall we watch one more episode? (kanka ‘buddy’, acayip ‘insanely’ as intensifier; informal)
Bugün hava baya soğuk, montunu al yanına.
It's pretty cold today, take your coat with you. (baya ‘pretty/quite’, informal intensifier)
Ya lan, otobüsü kaçırdık galiba.
Oh man, I think we missed the bus. (lan as rough emphasis; friendly only among close peers — avoid with strangers/elders/in formal settings)
Discourse particles: ya, işte, valla
What truly makes Turkish sound casual is not any single word but the density of discourse particles — small words that carry attitude rather than content. Three dominate everyday speech.
ya is the workhorse: it appeals to the listener, expresses mild frustration or insistence, and softens or intensifies depending on intonation — roughly "come on / you know / oh". işte means "you know, like, that's just how it is", filling pauses and flagging a conclusion. valla(hi) (originally an oath, "by God") has bleached into "honestly / I swear / really".
Hadi ya, bana hiç söylemedin bunu!
Come on — you never told me this! (ya as appeal / mild reproach)
İşte ben de onu diyorum, anlaşamıyoruz.
That's exactly my point — we just can't agree. (işte flags the conclusion)
Valla bilmiyorum, sana yarın haber veririm.
Honestly, I don't know — I'll let you know tomorrow. (valla ‘honestly / I swear’, bleached oath)
Çok yoruldum ya, biraz oturalım işte.
I'm so tired, you know — let's just sit for a bit. (ya + işte stacked, fully casual texture)
These particles cluster. A single sentence can carry ya … işte or open with valla and close with ya. For an English speaker the closest analogy is the way casual English layers "like", "you know", "I mean", and "honestly" — but in Turkish the particles are more grammaticalized and far more frequent, and leaving them out makes friendly speech sound oddly stiff.
A casual line and its standard equivalent
Here is a fully colloquial line paired with its neutral, standard-written counterpart so you can see the whole transformation at once.
Napıyon ya, bişey yiyek mi kanka?
Casual/non-standard: ‘What's up — wanna grab something to eat, buddy?’ (contractions napıyon, bişey; particle ya; slang kanka; informal -ek for -elim)
Ne yapıyorsun, bir şeyler yiyelim mi?
Standard: ‘What are you doing — shall we eat something?’ (same meaning, neutral register)
The standard line is what you would write or say to anyone; the casual line is what you would say to a close friend. Same grammar, completely different register.
Common mistakes
❌ Sayın müdürüm, napıyonuz, bişey sormak istiyodum.
Incorrect — colloquial reductions (napıyonuz, bişey, istiyodum) in a formal address to a manager; jarring register clash.
✅ Sayın müdürüm, nasılsınız, bir şey sormak istiyordum.
Sir/Madam, how are you — I wanted to ask something. (standard forms in a formal setting)
❌ Raporu yarın teslim ediyom.
Incorrect — the contraction -yom belongs to casual speech, never to written/professional Turkish.
✅ Raporu yarın teslim ediyorum.
I'm submitting the report tomorrow. (full -yorum in writing)
❌ Öğretmenine 'lan' diye seslenmek.
Incorrect — addressing a teacher with ‘lan’ is rude; lan is rough peer-only emphasis, not a neutral vocative.
✅ Öğretmenine 'hocam' diye seslenmek.
Calling your teacher ‘hocam’. (the respectful informal-but-polite address)
❌ Napıyon mu burada çalışıyon?
Incorrect — failing to parse the contraction: napıyon already means ‘what are you doing’, so this stacks a question on a question.
✅ Napıyon, burada mı çalışıyon?
What are you up to — do you work here? (napıyon = ne yapıyorsun, parsed correctly)
❌ Resmî e-postaya 'valla bilmiyom kanka' yazmak.
Incorrect — putting ‘valla bilmiyom kanka’ in a formal email; particle + contraction + slang all belong to casual speech only.
✅ Resmî e-postaya 'maalesef bu konuda bilgim yok' yazmak.
Writing ‘unfortunately I have no information on this’ in a formal email. (neutral register)
Key takeaways
- Casual Turkish uses systematic, predictable contractions (geliyom, napıyon, bişey, bi) — non-standard transcriptions that re-expand to ordinary grammar.
- Slang (kanka, acayip, baya) is productive and common but firmly informal; rough items like lan/ulan are friendly only among peers and rude elsewhere.
- Discourse particles (ya, işte, valla) carry attitude, cluster densely, and give casual speech its texture; omitting them makes friendly speech sound stiff.
- Learn this register for comprehension of media, music, and conversation — but keep contractions and slang out of any formal or written context.
