Kaseye yoğurt koyup dereotu karıştırdım, sonra turpu ince ince dilimledim.

Because -ye is the dative ending here, so kaseye means to the bowl / into the bowl.

• kase = bowl
• kaseye = to/into the bowl

The noun ends in a vowel, so Turkish inserts a buffer y before the case ending:

• kase + -e → kaseye

With koymak (to put), Turkish often uses the dative to show where something is being placed.

Koyup comes from koymak (to put) plus the converb ending -ıp / -ip / -up / -üp.

So koyup means something like:

• having put
• putting ... and then
• put ... and

In natural English, this sentence is simply saying that the speaker first put the yogurt in the bowl and then mixed in the dill.

A very important point: this -up form usually links actions done by the same subject. So here, the same person did both actions.

Because Turkish often links actions with the -ıp / -ip / -up / -üp form instead of using ve.

So:

• koyup karıştırdım = I put it in and mixed it
• more literally: having put [it], I mixed [it]

This is extremely common in Turkish when one person does a sequence of actions.

Here dereotu is an unmarked direct object, which often happens when the object is indefinite, non-specific, or treated like an ingredient.

So:

• dereotu karıştırdım = I mixed in dill
• dereotunu karıştırdım would sound more like I mixed in the dill / that specific dill

In cooking contexts especially, Turkish often leaves ingredient nouns unmarked like this.

Also, dereotu is the normal word for dill.

Because turpu is the accusative form of turp (radish), and that usually means the object is specific or definite.

• turp = radish
• turpu = the radish / that radish

So:

• turp dilimledim = I sliced radish / some radish
• turpu dilimledim = I sliced the radish

This is one of the most important Turkish patterns: a specific direct object usually takes the accusative ending.

This is a common Turkish reduplication pattern. Repeating ince adds emphasis and describes the manner of the action more vividly.

• ince = thin
• ince ince dilimlemek = to slice very thinly / into thin slices

So the repetition makes it sound more natural and expressive, something like:

• thinly
• nice and thin
• into very thin slices

Both verbs contain tense and person endings.

For example:

• karıştırdım

  • karıştır- = mix/stir
  • -dı- = past tense
  • -m = I

• dilimledim

  • dilimle- = slice
  • -di- = past tense
  • -m = I

So both mean I mixed and I sliced.

The exact vowel in the past ending changes by vowel harmony:

• -dı / -di / -du / -dü

Because Turkish often drops subject pronouns when the verb ending already makes the subject clear.

Since -m on the verb already means I, saying ben is usually unnecessary unless you want emphasis or contrast.

So:

• karıştırdım already means I mixed
• dilimledim already means I sliced

Adding ben would be possible, but not required.

Turkish normally puts the verb near the end of the clause, so it often follows a subject–object–verb pattern rather than English subject–verb–object.

In this sentence:

• Kaseye yoğurt koyup dereotu karıştırdım
• literally something like: Into the bowl yogurt putting dill mixed-I

That sounds strange in English, but it is natural in Turkish.

Turkish also tends to place:

• location/direction phrases earlier
• objects before the verb
• the main verb at the end

Sonra means then, after that, or later.

Here it marks the next step in the sequence:

• first: put yogurt in the bowl and mix in dill
• sonra: then
• next: slice the radish thinly

So it helps organize the actions in time, especially in instructions or narration.

Yoğurt is pronounced roughly like yo-urt, with the ğ not sounding like a hard consonant.

In modern Turkish, ğ usually:

• lengthens the preceding vowel, or
• creates a slight glide, or
• is barely pronounced at all

So yoğurt is not pronounced with a strong g sound.

For an English speaker, an approximate pronunciation is:

• YOH-oort or yo-urt

The exact sound depends a bit on accent, but the key point is: ğ is soft and never like the hard g in go.
