Leveransen kom sent, så nu vill hon göra en retur.

Leveransen is the definite form, meaning the delivery rather than a delivery.

• en leverans = a delivery
• leveransen = the delivery

In Swedish, the definite article is often added to the end of the noun:

• en bok = a book
• boken = the book

So Leveransen kom sent means The delivery arrived late.

Kom is the past tense of komma, which usually means to come. In contexts like deliveries, orders, buses, trains, and messages, Swedish often uses komma where English might use arrive.

• komma = to come
• kom = came

So Leveransen kom sent literally means The delivery came late, but in natural English that is often The delivery arrived late.

Because sent is the form used here as an adverb.

Compare:

• sen = late, in the common form used with nouns of en gender
  
  • en sen leverans = a late delivery
• sent = late, used as an adverb or with ett-words
  
  • Den kom sent = It came late
  • ett sent tåg = a late train

In this sentence, sent describes how the delivery came, so it works like an adverb: came late.

Here så means so or therefore.

It connects the two clauses:

• Leveransen kom sent = one situation
• så nu vill hon göra en retur = the result or consequence

So the meaning is: the delivery was late, so now she wants to make a return.

The comma separates two main clauses:

• Leveransen kom sent
• så nu vill hon göra en retur

In Swedish, a comma before så is common when it links two full clauses, especially when the sentence is a bit longer or when the writer wants the pause to be clear. In informal writing, commas can be somewhat flexible, but this comma is completely natural.

This is because Swedish follows the V2 rule in main clauses: the finite verb usually comes in the second position.

In nu vill hon göra en retur:

1. nu = first position
2. vill = second position
3. hon = subject after the verb

So:

• Nu vill hon göra en retur. = correct
• Nu hon vill göra en retur. = incorrect

This is very common in Swedish:

• I dag arbetar jag. = Today I am working.
• Nu vill hon... = Now she wants...

No. Swedish vill means want, not future will.

• jag vill = I want
• hon vill = she wants

So hon vill göra en retur means she wants to make a return.

This is a very common point for English speakers because vill looks similar to will, but the meanings are different.

Göra en retur means make a return or do a return, especially in shopping contexts.

• göra = do / make
• en retur = a return

It is understandable and natural in customer-service or retail language. Depending on context, Swedish speakers might also say:

• returnera varan = return the item
• skicka tillbaka den = send it back
• göra en retur = make a return

So this phrase is practical, especially for online shopping or store returns.

Retur is an en-word in Swedish, so it takes en in the indefinite singular:

• en retur = a return
• returen = the return

This is just something you have to learn with the noun. Swedish nouns are either en-words or ett-words.

Yes. A very natural alternative would be:

• ...så nu vill hon returnera den. = ...so now she wants to return it.

That version is often a bit more direct. The original sentence uses the noun phrase göra en retur, which sounds like the action as a store process. Both are fine, but the nuance is slightly different:

• göra en retur = make/process a return
• returnera den = return it

Yes, Swedish normally requires an explicit subject in a sentence, just like English.

So you need hon here:

• nu vill hon göra en retur

You generally cannot just leave it out. Swedish does not usually drop subject pronouns the way some other languages do.

It can mean either, depending on context, but most often leveransen refers to the delivery as an event or shipment in a shopping/logistics context.

For example, it could mean:

• the order arriving
• the shipment/delivery from the seller
• the delivery process connected to the purchase

In this sentence, it most likely refers to the delivery of her order.

Yes, that is grammatically possible, but it changes the emphasis.

• så nu vill hon göra en retur puts focus on now
• så vill hon nu göra en retur is also correct, but sounds a bit more marked or formal

The original sentence is the most natural everyday phrasing.

The original sentence is already natural, but everyday spoken Swedish might also use alternatives such as:

• Leveransen kom sent, så nu vill hon returnera den.
• Leveransen var sen, så nu vill hon skicka tillbaka den.

These all express roughly the same idea, but with slightly different wording:

• kom sent = arrived late
• var sen = was late
• göra en retur = make a return
• skicka tillbaka den = send it back
