Bu döner çok lezzetli.

In Turkish, the verb to be is often left out in the present tense when making simple statements.

So:

• Bu döner çok lezzetli = This döner is very delicious

Turkish does not need a separate word for is here.

You can think of the structure as:

• Bu döner = this döner
• çok lezzetli = very tasty

In other tenses or forms, Turkish does show this idea more clearly:

• Bu döner çok lezzetliydi = This döner was very delicious
• Bu döner çok lezzetli değil = This döner is not very delicious

So the missing is is completely normal.

Bu usually means this.

So:

• Bu döner = this döner

If you want to say that, Turkish often uses:

• şu = that / this over there / that one
• o = that / it / he / she

Very roughly:

• bu = this (near me)
• şu = that (pointing something out)
• o = that / it (farther away or already known)

In your sentence, bu is the natural choice for this döner.

Here, döner refers to döner kebab or simply döner, the food.

The letter ö is a separate Turkish vowel, not just a decorated o. It is pronounced somewhat like the vowel in German schön or French bleu. English does not have an exact match, so learners usually need practice hearing it.

Also, döner comes from the verb dönmek, meaning to turn / rotate, because the meat turns on a vertical spit.

So in this sentence, döner is just the noun: döner.

Because çok means very here, and in Turkish, words like very come before the adjective they modify.

So:

• çok lezzetli = very tasty

This is similar to English:

• very tasty
• not tasty very

Compare:

• çok güzel = very beautiful / very nice
• çok sıcak = very hot
• çok pahalı = very expensive

So çok lezzetli follows the normal Turkish pattern.

Not always. Çok can mean either very or many/a lot, depending on what it modifies.

In your sentence:

• çok lezzetli = very delicious

Here, çok modifies an adjective (lezzetli), so it means very.

But with nouns, it often means many or a lot of:

• çok insan = many people
• çok para = a lot of money

So the meaning depends on context and grammar.

Lezzetli means tasty, flavorful, or delicious.

It comes from:

• lezzet = taste, flavor
• -li = a suffix meaning with / having

So literally, lezzetli means something like with flavor or having taste.

This -li suffix is very common in Turkish:

• tuz = salt → tuzlu = salty
• şeker = sugar → şekerli = sugary / with sugar
• süt = milk → sütlü = milky / with milk

So lezzetli is a great example of a common Turkish word-building pattern.

There are actually two different patterns in Turkish, and that can confuse English speakers.

1. Attributive adjective: when the adjective comes directly before a noun

   • lezzetli döner = delicious döner

2. Predicate adjective: when the adjective is part of the statement

   • Bu döner çok lezzetli = This döner is very delicious

In your sentence, lezzetli is not directly describing the noun inside a noun phrase. It is the main description in the sentence, like delicious in This döner is delicious.

So:

• lezzetli döner = delicious döner
• Bu döner lezzetli = This döner is delicious

That is why the adjective appears after the noun here.

Yes, it is very natural and standard.

Turkish often uses a flexible word order, but the neutral order here is:

• Bu döner = topic / subject
• çok lezzetli = comment about it

So:

• Bu döner çok lezzetli.

You might also hear variations for emphasis, such as:

• Çok lezzetli bu döner. = This döner is really delicious.
• Lezzetli bu döner. = This döner is tasty.

But for a learner, Bu döner çok lezzetli is the safest and most neutral version.

Turkish does not use articles the way English does.

English requires words like:

• a
• an
• the

Turkish usually does not.

So:

• Bu döner already means this döner
• there is no need for a separate word like the

If Turkish wants to express a/an, it can use:

• bir = one / a

For example:

• Bir döner yedim. = I ate a döner.

But in your sentence, bu already identifies the noun, so no article is needed.

A simple learner-friendly pronunciation guide is:

• Bu ≈ boo
• döner ≈ DUR-ner or DUH-ner with rounded lips on the first vowel
• çok ≈ chok
• lezzetli ≈ lez-zet-lee

A few helpful points:

• ö is a rounded front vowel; English does not have it exactly.
• ç is pronounced like ch in chair.
• zz is pronounced as a strong z sound.
• Turkish stress can vary, but saying it smoothly as
  bu DÖ-ner çok lez-ZET-li
  will usually be understood.

Yes, you can, but the meaning is slightly different.

• Bu döner çok lezzetli = This döner is very tasty / delicious
• Bu döner çok güzel = This döner is very good / nice

Lezzetli is more specific to taste.
Güzel is broader and can mean good, nice, beautiful, or pleasant, depending on context.

For food, Turkish speakers often use both, but lezzetli is more precise if you want to emphasize flavor.

You usually make it negative by using değil.

So:

• Bu döner çok lezzetli değil. = This döner is not very delicious.

Notice that değil comes after the adjective phrase:

• çok lezzetli değil = not very delicious

You can also say:

• Bu döner lezzetli değil. = This döner is not delicious.

So for this kind of sentence, değil is the key negative word.

You can make it a yes/no question with mi:

• Bu döner çok lezzetli mi? = Is this döner very delicious?

A few things to notice:

• mi is the question particle
• it is written separately
• it usually comes after the word or phrase being questioned

Here it follows lezzetli:

• çok lezzetli mi?

You may also hear it with normal conversation intonation, but using mi is the standard grammatical way.
