Er det ikke jordbær i kjølebagen også?

Structurally, it is:

• Er det ...? = Is there / Are there ...?
• ikke = not
• jordbær = strawberries
• i kjølebagen = in the cooler bag
• også = too / also

So the whole sentence works like:

Isn’t there also strawberries in the cooler bag?
More natural English would usually be:

• Aren’t there strawberries in the cooler bag too?
• Isn’t there any strawberries in the cooler bag too?
• or, in more careful English, Aren’t there any strawberries in the cooler bag too?

Norwegian often uses this er det ...? pattern where English uses is there / are there.

Because Norwegian commonly uses det er to mean there is / there are.

Examples:

• Det er melk i kjøleskapet. = There is milk in the fridge.
• Det er jordbær i kjølebagen. = There are strawberries in the cooler bag.

To turn that into a yes/no question, Norwegian inverts the verb and subject:

• Det er jordbær ... → statement
• Er det jordbær ...? → question

So Er det ikke ...? is literally something like Is there not ...?, which in natural English becomes Isn’t there ...? or Aren’t there ...?

That’s because det here is a dummy subject. It does not refer to a specific thing.

In English, we do the same with there:

• There is a book on the table.
• There are strawberries in the bag.

Norwegian uses det in many sentences where English uses there:

• Det er en bok på bordet.
• Det er jordbær i kjølebagen.

So in this sentence, det is not really it. It is just part of the existential pattern det er = there is / there are.

Because in Norwegian yes/no questions, the finite verb comes first, then the subject, and ikke usually comes after the subject.

So:

• Er = verb
• det = subject
• ikke = negation

Pattern:

• Er det ikke ...?

Compare:

• Det er ikke jordbær i kjølebagen. = There aren’t strawberries in the cooler bag.
• Er det ikke jordbær i kjølebagen? = Aren’t there strawberries in the cooler bag?

This is normal Norwegian word order.

Because Norwegian often leaves out the article in this kind of general existential sentence.

• Det er jordbær i kjølebagen. = There are strawberries in the cooler bag.

You could add something like noen in some contexts, but it is often unnecessary.

Also, jordbær is one of those nouns whose indefinite singular and indefinite plural look the same:

• et jordbær = a strawberry
• jordbær = strawberries

So here jordbær is understood as plural or as an uncounted quantity, depending on context. In natural English, we usually translate it as strawberries.

Most likely plural in meaning: strawberries.

The noun behaves like this:

• singular indefinite: et jordbær = a strawberry
• singular definite: jordbæret = the strawberry
• plural indefinite: jordbær = strawberries
• plural definite: jordbærene = the strawberries

So the form jordbær by itself can be either singular indefinite after et, or plural indefinite with no article. In this sentence, it is understood as plural.

Kjølebagen means the cooler bag or the insulated bag.

It is made from:

• kjøle- = cooling / cool
• bag = bag
• -en = the definite ending, so the bag

So:

• en kjølebag = a cooler bag
• kjølebagen = the cooler bag

This is a compound noun, which is very common in Norwegian.

Because i means in, and a cooler bag is treated as something with contents inside it.

• i kjølebagen = in the cooler bag

You would use på if something were physically on top of it:

• på kjølebagen = on the cooler bag

So if the strawberries are inside the bag, i is the natural preposition.

Også means also / too / as well.

In this sentence, it suggests that strawberries are being added to something already mentioned. For example:

• maybe there are sandwiches in the cooler bag, and the speaker is asking whether there are strawberries there too
• or maybe there are strawberries somewhere else, and the speaker is asking whether there are strawberries in the cooler bag as well

So også gives the sense of in addition.

Yes, også can sometimes move, but the position affects what it emphasizes.

Your sentence:

• Er det ikke jordbær i kjølebagen også?

This sounds natural and often emphasizes the idea of too / as well at the end.

Another possible version:

• Er det ikke også jordbær i kjølebagen?

This can sound a bit more like Aren’t there also strawberries in the cooler bag?

The difference is subtle, but placement can shift the emphasis:

• ... også? often sounds a little more conversational and final
• også jordbær ... puts more focus on strawberries as the additional item

Both can be correct depending on context.

It often expects confirmation.

A negative question like Er det ikke ...? frequently suggests that the speaker thinks the answer is probably yes, or that they thought something was true and want to check.

So it can sound like:

• Aren’t there strawberries in the cooler bag too?
• I thought there were strawberries there as well?

This kind of question can express:

• mild surprise
• checking a memory
• expecting agreement
• reminding someone of something

Not naturally.

Even though det often means it, here the construction is existential: det er = there is / there are.

So English should use there, not it:

• Er det jordbær i kjølebagen? = Are there strawberries in the cooler bag?
• not Is it strawberries in the cooler bag?

Using it in English would change the meaning completely.

It could, but it would sound different.

• Finnes det jordbær i kjølebagen også? = Are there / do there exist strawberries in the cooler bag too?

This is more about whether something exists / can be found, and it is less everyday in this context.

For ordinary conversation about what is in a bag, er det is much more natural:

• Er det jordbær i kjølebagen?

So the original sentence is the most idiomatic choice.

The statement version would be:

• Det er ikke jordbær i kjølebagen også.
  But this exact version is a bit awkward because of også and context.

A more natural positive statement would be:

• Det er jordbær i kjølebagen også. = There are strawberries in the cooler bag too.

And the negative statement without also:

• Det er ikke jordbær i kjølebagen. = There aren’t strawberries in the cooler bag.

The question is formed by inversion:

• Det er ... → statement
• Er det ...? → question

The meaning is basically the same, but the placement follows Norwegian word order, not English word order.

English:

• There are not strawberries in the bag.
• Are there not strawberries in the bag?
• more natural: Aren’t there strawberries in the bag?

Norwegian:

• Det er ikke jordbær i kjølebagen.
• Er det ikke jordbær i kjølebagen?

So when learning Norwegian, it is best not to translate word for word. Just remember the pattern:

• statement: Det er ikke ...
• question: Er det ikke ...?

A few common answers would be:

• Jo, det er det. = Yes, there are.
• Ja, det er det. can occur, but with negative questions jo is especially important
• Nei, det er det ikke. = No, there aren’t.

Why jo? Because Norwegian often uses jo to contradict a negative statement or negative question.

So if someone asks:

• Er det ikke jordbær i kjølebagen også?

and the answer is actually yes, there are, then jo is often the best answer.

A few natural translations are:

• Aren’t there strawberries in the cooler bag too?
• Isn’t there any strawberries in the cooler bag too?
• Weren’t there strawberries in the cooler bag too? if the context is about memory and the tense shifts in English

The best translation depends on the context, but Aren’t there strawberries in the cooler bag too? is usually the most straightforward.
