Kartongen står på golvet i förrådet.

Because -en makes the noun definite.

• en kartong = a box / a carton
• kartongen = the box / the carton

Kartong is an en-word, so its singular definite form is kartongen.

Swedish often uses special verbs for how something is positioned, where English just says is.

Here, står literally means stands, and it is used for things that are thought of as being upright or resting on their base. A box on the floor is often described this way in Swedish.

So:

• Kartongen står på golvet = idiomatic Swedish
• Kartongen är på golvet = understandable, but less specific and often less natural

Sometimes, yes, but it changes the image.

• står suggests the box is upright
• ligger suggests it is lying down, perhaps on its side

So the choice depends on how the object is positioned, not just where it is.

Because på means on, and a box is normally on the floor’s surface.

• på golvet = on the floor
• i golvet = in the floor

So i golvet would suggest something is inside the floor or embedded in it, which is not what is meant here.

Because i means in / inside, and a förråd is treated as an enclosed space.

So:

• på golvet = on the floor
• i förrådet = in the storage room

Together, they describe location more precisely: the box is on the floor, and that floor is inside the storage room.

Here, förrådet means the storage room, the storeroom, or the storage space.

The base word is:

• ett förråd = a storage room / a store of supplies

The definite form is:

• förrådet = the storage room

Depending on context, förråd can also mean supplies or stock, but in this sentence it clearly refers to a place.

Because Swedish nouns belong to two main groups:

• en-words
• ett-words

Their definite singular endings are usually:

• en-word → -en
• ett-word → -et

In this sentence:

• en kartong → kartongen
• ett golv → golvet
• ett förråd → förrådet

So the ending depends on whether the noun is an en noun or an ett noun.

Swedish marks definiteness directly on the noun. In this sentence, all three nouns are specific:

• kartongen = the box
• golvet = the floor
• förrådet = the storage room

English uses the separate word the, but Swedish usually adds the definite ending to the noun instead.

The structure is:

• Kartongen = subject
• står = verb
• på golvet = place
• i förrådet = more specific place

So the sentence follows a normal main-clause pattern:

Subject + verb + place

Swedish main clauses usually keep the finite verb in second position.

Yes, but then you must still keep the verb in second position.

For example:

• I förrådet står kartongen på golvet.

That is possible because Swedish follows the V2 rule in main clauses: the finite verb comes second, even if you begin with a time or place phrase.

A rough guide is: fur-ROH-det, but that is only approximate.

A few points:

• ö does not exist in English; it is somewhat like the vowel in British bird, but without an r
• å is a different vowel, roughly like the vowel in law
• the stress is on the second part: förrÅdet

So the stressed part is rå.

It can be, but it depends on the type of box.

• kartong often suggests a cardboard box or carton
• låda is a more general word for box, drawer, or container

So kartongen is perfectly natural if you mean a cardboard box/carton. If you mean a generic box, lådan might be another possibility in a different context.

No. In Swedish, the definite meaning is already built into the nouns:

• kartongen
• golvet
• förrådet

So Swedish does not need a separate word like English the here. The endings carry that meaning.
