If daha is "more," en is "most." The superlative in Turkish is almost embarrassingly simple at first: put the single, invariant word en in front of any adjective and you have the superlative — en büyük "biggest," en güzel "most beautiful." There is no -est, no irregular forms, nothing to harmonize. The only part that takes real learning is how to say "the [most X] of the Ys" — and for that Turkish reaches for the izafet possessive construction. This page covers both.
en + adjective = the superlative
Place en immediately before the adjective. en is a separate word and invariant — it never changes, never attaches, never harmonizes. The adjective stays in its plain form.
- büyük "big" → en büyük "the biggest"
- iyi "good" → en iyi "the best"
- pahalı "expensive" → en pahalı "the most expensive"
Bu, gördüğüm en güzel film.
This is the most beautiful film I've ever seen.
Sınıftaki en iyi öğrenci o.
He's the best student in the class.
Bu mağazadaki en pahalı ceket hangisi?
Which is the most expensive jacket in this shop?
Just like with daha, there is no choice to make between an ending and a word, and no irregular superlatives to memorize. iyi "good" simply becomes en iyi "best" — Turkish has no equivalent of the English jump from "good" to "best." One pattern, every adjective.
en directly before the noun's adjective
When the superlative describes a noun, en still sits right before the adjective, and the adjective right before the noun, exactly in the normal adjective slot: en güzel film "the most beautiful film," en yüksek dağ "the highest mountain."
Everest, dünyanın en yüksek dağı.
Everest is the world's highest mountain.
O, hayatımın en güzel günüydü.
That was the most beautiful day of my life.
Note in dünyanın en yüksek dağı "the world's highest mountain" that en yüksek "highest" modifies dağ "mountain," and the whole thing is wrapped in a possessive ("the world's …"). That possessive wrapping is the key to the next, more advanced pattern.
"The most X of the Ys": the izafet partitive
To say "the [smartest / tallest / hardest-working] of the [students / players / cities]," Turkish does not use a word for "of." It builds a possessive izafet: the group goes in the genitive (-(n)In), and the superlative adjective takes the third-person possessive ending -(s)I, turning the adjective into a noun-like head meaning "the X one of them."
The template is: [Group]-GENITIVE + en + Adjective-(s)I — literally "the group's most-X-one."
- öğrenciler "students" → öğrenci*lerin en çalışkanı* "the hardest-working of the students"
- sınıf "class" → sınıf*ın en uzunu* "the tallest in the class"
Bu çocuk, ailenin en çalışkanı.
This kid is the hardest-working in the family.
Öğrencilerin en başarılısı bu yıl mezun oluyor.
The most successful of the students is graduating this year.
Ali, sınıfın en uzunu, her zaman arkada otururdu.
Ali, the tallest in the class, always used to sit at the back.
Look closely at sınıfın en uzunu: sınıf takes the genitive -ın ("the class's"), and uzun "tall" takes the possessive -u ("its tall one") with the buffer -s- appearing only after vowels. So uzun + u = uzunu, but çalışkan + ı = çalışkanı, and a vowel-final adjective like iyi would take the buffer: en iyisi "the best of them." The adjective, by taking the possessive ending, becomes the head of the phrase — it now means "the X one," a thing, not just a description.
"One of the most X": en + adjective + -lardan biri
A related everyday pattern is "one of the most X," which combines the superlative with an ablative partitive. You make the superlative adjective plural and possessive, put it in the ablative, and add biri "one": en … -larından biri.
İstanbul, dünyanın en kalabalık şehirlerinden biri.
Istanbul is one of the most crowded cities in the world.
Bu, gördüğüm en güzel manzaralardan biriydi.
That was one of the most beautiful views I'd ever seen.
You can absorb this as a fixed frame for now: en [adjective] [noun]-lerinden biri = "one of the most [adjective] [noun]s." It appears constantly in writing and speech about places, films, and people.
Common mistakes
❌ Bu en büyüğest.
Incorrect — there is no -est ending; the superlative is just en + adjective: en büyük.
✅ Bu en büyük.
This is the biggest.
❌ Bu en daha güzel.
Incorrect — don't stack en and daha. en = 'most', daha = 'more'; choose one. For superlative use en alone.
✅ Bu en güzel.
This is the most beautiful.
❌ Sınıfın en uzun.
Incorrect — when the adjective is the head ('the tallest of the class'), it must take the possessive -(s)I: sınıfın en uzunu.
✅ Sınıfın en uzunu.
The tallest in the class.
❌ Öğrenciler en çalışkanı.
Incorrect — the group must take the genitive: öğrencilerin.
✅ Öğrencilerin en çalışkanı.
The hardest-working of the students.
❌ Dünyada en yüksek dağ.
Incorrect for 'the world's highest mountain' — use the genitive izafet: dünyanın en yüksek dağı.
✅ Dünyanın en yüksek dağı.
The world's highest mountain.
The two reflexes to retrain are adding -est (there isn't one — just en) and stacking en daha (you never combine "most" and "more"). The genuinely new skill is the izafet partitive: genitive on the group, possessive -(s)I on the superlative head.
Key takeaways
- The superlative is en + adjective — one invariant word, no -est, no irregulars: en iyi, en pahalı, en yüksek.
- en sits in the normal adjective slot before the noun: en güzel film, en yüksek dağ.
- "The most X of the Ys" is an izafet partitive: Ys-GENITIVE + en + Adjective-(s)I, e.g. öğrencilerin en çalışkanı, sınıfın en uzunu.
- "One of the most X" is en [adj] [noun]-lerinden biri: dünyanın en kalabalık şehirlerinden biri.
- Never stack en and daha — see the daha vs en guide for keeping the comparative and superlative apart.

- Comparatives with daha and AblativeA1 — To compare, put daha 'more' before the adjective and mark the thing you compare against with the ablative -DAn — there is no separate word for 'than' and no -er ending.
- Definite Izafet: Ali'nin EviA2 — The definite izafet builds 'X's Y' with two markers at once — genitive on the owner, 3rd-person possessive on the owned — and both ends must agree or the phrase breaks.
- Adjectives: No AgreementA1 — Turkish attributive adjectives go before the noun and never agree — in number, gender, or case. All the inflection lives on the noun, so güzel is identical in güzel ev, güzel evler, and güzel evde.
