På marknaden säljer de gurka och paprika för trettio kronor kilot.

Because Swedish follows the V2 rule in main clauses: the finite verb normally comes in the second position.

So when På marknaden is placed first for emphasis or as the topic, the verb säljer must come next, and the subject de comes after it:

• De säljer gurka ... = normal subject-first order
• På marknaden säljer de gurka ... = place first, so verb still stays second

This is very common in Swedish and is one of the first big word-order patterns learners notice.

Here de means something like they, but not necessarily a specific named group. It often refers more generally to the people selling things there, or people at the market.

In English, we often use:

• they
• people
• you (in a general sense)
• or a passive structure such as cucumbers and peppers are sold...

So de here is a very natural way to refer to unnamed sellers.

In normal spoken Swedish, de is usually pronounced dom.

So although it is written de, you will often hear something close to:

• dom säljer

This is true in most everyday speech. In writing, Swedish traditionally distinguishes:

• de = subject form
• dem = object form

But in speech, both are very often pronounced dom.

Swedish uses på with many places and events where English might use at rather than in. So på marknaden means at the market.

Compare:

• på jobbet = at work
• på festen = at the party
• på restaurangen = at the restaurant

Using i marknaden would usually sound wrong here, because the idea is not being physically inside something enclosed, but being at the market as a place/event.

Marknaden is the definite form, meaning the market.

Swedish often uses the definite form when talking about a known or contextually understood place:

• på marknaden = at the market
• på stationen = at the station
• på banken = at the bank

If you said på en marknad, that would mean at a market or at some market, not a specific or understood one.

This is a very common pattern with food and goods in Swedish. Bare singular nouns can be used to mean a type of product rather than one single item.

So:

• säljer gurka och paprika means they sell cucumber and bell pepper as goods/produce
• it does not focus on one cucumber and one pepper

If you said:

• säljer en gurka och en paprika

that would sound like they are selling one cucumber and one pepper.

Swedish often treats food words this way in shopping, cooking, and market contexts.

Yes, but it changes the nuance.

• gurka och paprika = cucumber and bell pepper as products/types of produce
• gurkor och paprikor = cucumbers and peppers as individual items

Both can be correct, but the singular bare form is very natural when talking about what a shop or market stall sells in general.

Here it almost certainly means the vegetable: bell pepper / sweet pepper.

The context makes that clear:

• it appears with gurka
• it is sold för trettio kronor kilot

That sounds like fresh produce, not powdered spice.

Swedish paprika can refer to the vegetable, and in some contexts also paprika spice, so context matters.

Because after numbers greater than one, Swedish normally uses the plural form of the noun.

So:

• en krona = one krona
• trettio kronor = thirty kronor

This is just ordinary number agreement.

Kilot literally means the kilo. It is the definite form of kilo.

In price expressions, Swedish often uses this definite form idiomatically to mean per kilo:

• trettio kronor kilot = thirty kronor per kilo

This is a very common market/shop expression. It sounds natural in everyday Swedish.

Yes. That is also correct.

• för trettio kronor kilot = more idiomatic, everyday, market-style
• för trettio kronor per kilo = also correct, a bit more explicit

Both mean the same thing.

In this sentence, för means for in the sense of at the price of.

So:

• säljer ... för trettio kronor kilot = sell ... for thirty kronor a kilo

This is a very common use of för with prices in Swedish.

Säljer is the present tense of sälja, which means to sell.

So:

• sälja = infinitive, to sell
• säljer = present, sell / are selling

In Swedish, the present tense is often used where English might say either:

• sell
• are selling

depending on context.
