Pırasa yemeği soğumasın diye sofraya hemen oturalım.

Here diye introduces a purpose clause. In this sentence, soğumasın diye means so that it doesn’t get cold or so it won’t get cold.

This is a very common pattern in Turkish:

• Verb + diye = so that ...
• especially with a negative form like olmasın diye, geç kalmayalım diye, unutmasın diye

So the sentence is organized as:

• Pırasa yemeği soğumasın diye = so that the leek dish doesn’t get cold
• sofraya hemen oturalım = let’s sit down at the table right away

Soğumasın comes from soğumak meaning to get cold / to cool down.

It breaks down like this:

• soğu- = verb stem
• -ma- = negation
• -sın = a 3rd person singular wish/command form

So soğumasın literally means something like let it not get cold.

In English, that literal meaning sounds odd by itself, but with diye it becomes a natural purpose expression:

• soğumasın diye = so that it doesn’t get cold

This kind of form is very normal in Turkish.

Yes. Pırasa yemeği soğumaması için sofraya hemen oturalım is also grammatical and means essentially the same thing.

The difference is mostly stylistic:

• soğumasın diye sounds very natural and everyday
• soğumaması için is also common, but can sound a little more formal or more structurally explicit

So a learner should understand both patterns:

• Verb-negative-imperative + diye
• Verb-nominalized negative + için

Both can express so that ... not ...

In this sentence, soğumak means to get cold or to cool down by itself.

It is an intransitive verb: the thing itself changes state.

• Yemek soğudu = the food got cold

If you mean to cool something actively, Turkish usually uses soğutmak:

• Yemeği soğuttum = I cooled the food

So here the dish is not being cooled by someone; it is simply becoming cold.

Oturalım comes from oturmak meaning to sit or to sit down.

The ending -alım here gives a let’s ... meaning:

• oturalım = let’s sit down
• gidelim = let’s go
• başlayalım = let’s begin

This form is often called the 1st person plural imperative or hortative/optative form.

So sofraya hemen oturalım means let’s sit down at the table right away.

Sofraya oturmak is the natural expression for to sit down at the table.

The ending -a / -e is the dative. Here it suggests movement toward or taking one’s place at the table.

Compare:

• sofraya oturmak = to sit down at the table
• sofrada olmak = to be at the table

So sofraya fits well because the speaker is suggesting an action: let’s go take our places at the table now.

Also, sofraya oturmak is a very common Turkish collocation, so it is best learned as a set phrase.

Here sofra means more than just the physical table. It often refers to the meal setting, dining table, or table prepared for eating.

So sofraya oturmak is not just physically sitting near furniture. It often implies sitting down to eat.

That is why sofra can sound a little more meal-centered than masa.

• masa = table as an object
• sofra = the eating table / meal setting

Pırasa yemeği is a noun compound.

It consists of:

• pırasa = leek
• yemek = food / dish / meal
• yemeği = yemek with the compound ending

Together, pırasa yemeği means a leek dish, leek stew, or the leek dish, depending on context.

This is a very common Turkish pattern for food names:

• sebze çorbası = vegetable soup
• tavuk yemeği = chicken dish
• elma suyu = apple juice

So this is not saying the leek’s food. It is simply naming a type of dish.

No. In pırasa yemeği, the -i is not the accusative.

It is part of the noun compound structure. In these compounds, the second noun usually takes a form often called the 3rd person possessive suffix, even though the meaning is not true possession in English.

So:

• pırasa yemeği = leek dish
• not an object marked by accusative

This matters because a learner might think yemeği is a direct object, but it is not. In this sentence, the whole phrase pırasa yemeği is the thing that might get cold.

Turkish does not have a definite article like English the.

So whether we translate pırasa yemeği as:

• the leek dish
• the leek stew
• leek dish

depends on context.

In this sentence, the food is presumably already on the table or known to both speakers, so English naturally uses the. Turkish does not need a separate word for that.

Not completely. Turkish word order is flexible, although some orders sound more neutral than others.

The given sentence is very natural:

• Pırasa yemeği soğumasın diye sofraya hemen oturalım

You could also hear:

• Pırasa yemeği soğumasın diye hemen sofraya oturalım

Both are fine. The difference is mainly emphasis.

In general:

• the main verb often comes at the end
• the purpose clause with diye often comes before the main clause
• words like hemen can move around a bit

So the order is flexible, but not random.

Turkish often leaves subject pronouns out because the verb ending already shows the person.

Here oturalım already means let’s sit down, so we is built into the verb.

That is why biz is unnecessary.

You could add biz for emphasis, but it would not usually be needed:

• Biz sofraya hemen oturalım

In normal speech, Turkish prefers the shorter version unless there is a special reason to stress the subject.

Hemen means immediately, right away, or at once.

In this sentence, it adds urgency:

• the food may get cold
• so the speaker suggests sitting down without delay

So hemen helps connect the purpose and the action very naturally. Without it, the sentence would still make sense, but it would sound a little less urgent.
