Kayısı reçeli bitince, annem marketten yenisini alacak.

Bitince comes from the verb bitmek, which means to end, to be finished, or to run out.

The ending -ince means when, once, or after in a time-clause sense.

So:

• bitmek = to end / to run out
• bitince = when it runs out / once it is finished

In this sentence, Kayısı reçeli bitince means When the apricot jam runs out.

Because bitmek is an intransitive verb. It describes something ending by itself or being used up.

Here, the jam is the thing that runs out:

• Reçel bitti = The jam ran out / The jam is finished

If you wanted to say that someone finished something, Turkish often uses the transitive verb bitirmek:

• Reçeli bitirdim = I finished the jam

So in this sentence, bitince is correct because the apricot jam is the thing that becomes finished.

Because kayısı reçeli is a very common Turkish noun compound structure.

Turkish often forms expressions like X jam, X soup, X juice, X door, etc. by putting two nouns together, and the second noun usually takes a compound ending.

So:

• kayısı = apricot
• reçel = jam
• kayısı reçeli = apricot jam

That -i on reçeli is part of the compound structure. Similar examples:

• elma suyu = apple juice
• tavuk çorbası = chicken soup
• araba kapısı = car door

So kayısı reçeli is the normal way to say apricot jam.

Because it is not the direct object of the main verb alacak. It belongs to the time clause:

• Kayısı reçeli bitince = when the apricot jam runs out

Inside that clause, kayısı reçeli is the thing that runs out, so it acts like the subject of bitince, not a direct object.

That is why it does not become kayısı reçelini here.

Because annem is:

• anne = mother
• -m = my

So:

• anne = mother
• annem = my mother

Turkish often attaches possessive endings directly to the noun instead of using a separate word like my.

Examples:

• ev = house

• evim = my house

• kardeş = sibling
• kardeşim = my sibling

So annem marketten yenisini alacak means my mother will buy a new one from the store.

Marketten is:

• market = market / grocery store / small supermarket
• -ten = from

So marketten literally means from the store.

In Turkish, when talking about buying something, the place you buy it from is often marked with the ablative ending -den / -dan / -ten / -tan.

So:

• marketten almak = to buy from the store

That is why the sentence says annem marketten yenisini alacak.

Yenisini means the new one or, in natural English here, a new one.

It is based on yeni, meaning new, but Turkish often turns adjectives into pronoun-like words meaning the ... one.

Here is the breakdown:

• yeni = new
• yenisi = the new one / its new one
• yenisini = the new one as a direct object

The final -ni marks it as the object of alacak:

• alacak = will buy
• yenisini alacak = will buy the new one / will buy a new one

This pattern is very common in Turkish:

• kırmızısını istiyorum = I want the red one
• büyüğünü aldım = I bought the big one
• eskisini attı = He threw away the old one

So yenisini is a very natural Turkish way to say a new one when the noun is already understood.

In Turkish, the accusative often shows that the object is specific or already understood.

Here, everyone knows what one means: a new jar of apricot jam, or a replacement for the old one. So Turkish treats it as a specific understood object:

• yenisini alacak = she will buy the new one / she will buy a replacement one

If you said yeni bir tane alacak, that would sound more like she will buy a new one in a less specific way.

So the accusative in yenisini is very natural here because it refers to a clearly understood replacement item.

Because Turkish normally puts the main verb at the end of the clause or sentence.

So the structure is roughly:

• Kayısı reçeli bitince = when the apricot jam runs out
• annem = my mother
• marketten = from the store
• yenisini = a new one
• alacak = will buy

This verb-final order is very typical in Turkish.

Alacak is the future tense of almak, meaning to buy.

• almak = to buy / to take
• alacak = he/she will buy

It is used because the buying will happen later, after the jam runs out.

So the whole sentence describes a future plan or expected future action:

• When the apricot jam runs out, my mother will buy a new one from the store.

It can often be translated in all three ways, depending on context.

In this sentence:

• when the apricot jam runs out
• once the apricot jam runs out
• after the apricot jam runs out

All are close in meaning.

The basic idea is that one action happens at the time of or following another action. Here, the jam runs out first, and then the mother buys more.
