Gafflarna ligger kvar i diskmaskinen, men knivarna är redan rena.

Because -na is the definite plural ending here. It means the.

• gafflar = forks
• gafflarna = the forks
• knivar = knives
• knivarna = the knives

In Swedish, the definite article is often attached to the end of the noun instead of being a separate word like the in English.

Swedish usually puts definiteness on the noun itself as a suffix.

So instead of saying something like the forks, Swedish says gafflarna.

The same pattern appears in:

• diskmaskinen = the dishwasher
• gafflarna = the forks
• knivarna = the knives

This is very normal in Swedish and one of the first big differences English speakers notice.

Ligga kvar means something like remain, still be left, or more literally be lying there still.

In this sentence, Gafflarna ligger kvar i diskmaskinen suggests that the forks are still in the dishwasher and have not been taken out yet.

The verb ligga is often used for things that are physically positioned somewhere, especially objects resting somewhere.

Swedish often prefers a position verb where English would simply use be.

Here:

• ligger kvar gives a physical sense: the forks are still lying in the dishwasher.
• är kvar would also be possible in many contexts, but it is a little less vivid about physical position.

So ligger sounds natural because forks are objects resting somewhere.

Kvar means left, still there, or remaining.

It often appears in sentences where something has not moved, disappeared, or been dealt with yet.

Examples:

• Jag är kvar hemma. = I am still at home.
• Det finns kaffe kvar. = There is coffee left.
• Gafflarna ligger kvar i diskmaskinen. = The forks are still left in the dishwasher.

So kvar adds the idea that the forks have not been removed yet.

Because Swedish usually uses the definite form when talking about a specific, known object in the situation.

• diskmaskin = dishwasher
• diskmaskinen = the dishwasher

In a normal home situation, both speaker and listener know which dishwasher is meant, so i diskmaskinen is the natural choice.

Because rena agrees with the plural noun knivarna.

Swedish adjectives change form depending on number and definiteness. Here, knivarna is plural definite, so the adjective takes the plural/definite form rena.

Compare:

• en ren kniv = a clean knife
• kniven är ren = the knife is clean
• rena knivar = clean knives
• knivarna är rena = the knives are clean

So rena matches knivarna.

Because redan is an adverb, and in this kind of sentence it naturally comes after the verb är and before the adjective.

So:

• knivarna är redan rena

This is a very common Swedish pattern: subject + verb + adverb + complement

Other examples:

• Hon är redan trött. = She is already tired.
• Maten är redan kall. = The food is already cold.

Men means but and connects two clauses that contrast with each other.

The contrast here is:

• the forks are still in the dishwasher
• the knives are already clean

So the sentence sets up a difference between the two groups of items.

Structurally:

• Gafflarna ligger kvar i diskmaskinen
• men knivarna är redan rena

This is a very typical way to build contrast in Swedish.

The singular forms are:

• en gaffel = a fork
• gaffeln = the fork
• en kniv = a knife
• kniven = the knife

Their plural forms are:

• gafflar = forks
• gafflarna = the forks
• knivar = knives
• knivarna = the knives

A learner often needs to memorize both singular and plural patterns, because Swedish plural formation is not always fully predictable.

Yes, that would be understandable and often natural.

But there is a slight nuance:

• är kvar = are still there / remain
• ligger kvar = are still lying there

So ligger kvar sounds a bit more concrete and physical, which fits well for utensils in a dishwasher.

Both can work, but ligger kvar is especially natural for objects resting somewhere.

Because men does not automatically force inversion. After men, Swedish normally keeps ordinary main-clause word order unless another element has been moved to the front.

So this is normal:

• men knivarna är redan rena

If you started with another element, then the verb would come earlier because of Swedish V2 word order:

• men redan är knivarna rena — possible in a special style, but not the most natural everyday version here
• men nu är knivarna rena = but now the knives are clean

In the original sentence, the straightforward word order is the most natural.

Yes: both parts follow normal Swedish main-clause order.

Clause 1:

• Gafflarna = subject
• ligger = verb
• kvar i diskmaskinen = rest of the clause

Clause 2:

• knivarna = subject
• är = verb
• redan rena = rest of the clause

This is a basic Swedish pattern: the finite verb comes early in the clause, usually in the second position in main clauses. The sentence is therefore a good example of ordinary, natural Swedish word order.
