Kopplet ligger bredvid transportburen.

Because kopplet is the definite singular form of koppel, meaning the leash / the lead.

• ett koppel = a leash
• kopplet = the leash

Swedish usually adds the definite article to the end of the noun instead of using a separate word like the.

Since koppel is an ett-word (neuter noun), its definite singular ending is -et.

For the same reason: transportburen is the definite singular form, meaning the carrier / the pet crate.

• en transportbur = a carrier
• transportburen = the carrier

Here, transportbur is an en-word (common gender noun), so the definite singular ending is -en.

Because they belong to different grammatical genders in Swedish.

• ett koppel → kopplet
• en transportbur → transportburen

Swedish nouns are mainly divided into two genders:

• en-words
• ett-words

The gender affects which article and definite ending the noun gets.

Swedish often uses specific position verbs where English might simply use is.

Here, ligger means lies / is lying and is used for something that is positioned horizontally or simply located in a way Swedish conceptualizes as lying.

So Swedish prefers:

• Kopplet ligger bredvid transportburen.

rather than a more general is construction.

This is very common in Swedish:

• Boken ligger på bordet. = The book is on the table.
• Stolen står vid väggen. = The chair is by the wall.
• Barnet sitter i bilen. = The child is in the car.

English often uses is, but Swedish often chooses ligger, står, or sitter depending on position.

It is the present tense of ligga, which usually means to lie or to be lying.

In this sentence, it describes the leash as being located next to the carrier. It can sound more natural in Swedish than a direct equivalent of is.

So ligger here is both:

• a literal position verb, and
• the natural way to describe where the leash is.

Bredvid means beside, next to, or by the side of.

It is a preposition introducing the location:

• bredvid transportburen = next to the carrier

So the structure is:

• Kopplet = subject
• ligger = verb
• bredvid transportburen = location phrase

Yes. Swedish very often forms compound nouns by joining words together.

Here:

• transport = transport
• bur = cage / crate / carrier

Together, transportbur means something like transport cage, usually a pet carrier or animal crate depending on context.

This is very normal in Swedish. English sometimes writes similar ideas as two words, but Swedish commonly makes them one word.

Yes, but the verb still has to stay in the second position in a main clause because Swedish follows the V2 rule.

The original sentence:

• Kopplet ligger bredvid transportburen.

You could also say:

• Bredvid transportburen ligger kopplet.

That version puts more focus on the location first, but ligger still stays in second position.

Koppel usually refers to a leash / lead, especially for a dog or other pet.

In everyday usage, many learners will most often meet it in pet-related contexts. In British English, lead is often the most natural translation; in American English, leash is usually more natural.

It would be:

• Ett koppel ligger bredvid en transportbur.

That means A leash is lying next to a carrier.

Compare:

• Kopplet ligger bredvid transportburen. = The leash is next to the carrier.
• Ett koppel ligger bredvid en transportbur. = A leash is next to a carrier.

So the original sentence is talking about specific, identifiable things.

A learner should notice that Swedish compounds are usually pronounced as one unit, and the stress often falls strongly near the beginning of the compound.

A rough guide:

• kopplet ≈ KOP-let
• bredvid ≈ bred-VEED
• transportburen ≈ trans-PORT-buu-ren

The exact pronunciation depends on accent and dialect, but the main thing is to treat transportburen as one word, not as separate words.

Sometimes, yes, depending on the exact meaning.

For example:

• intill = right next to / adjacent to
• vid = by / at
• nära = near

But bredvid specifically gives the idea of beside or next to, so it is a very natural choice here if the leash is right next to the carrier.
