Vi ska måla om köket efter lunch.

ska + infinitive is a very common way to talk about a planned future action in Swedish.

• Vi ska måla om köket = We are going to repaint the kitchen
• Vi målar om köket usually sounds more like We are repainting the kitchen or We repaint the kitchen, depending on context

So ska here shows intention or plan.

Also note that after ska, the next verb stays in the infinitive:

• ska måla
• not ska målar

In Swedish, modal verbs like ska, kan, vill, måste, and bör are normally followed directly by the infinitive, without att.

So you get:

• Vi ska måla om köket
• Jag kan simma
• Hon vill gå hem

Not:

• Vi ska att måla om köket

That would be incorrect.

Måla means to paint.
Måla om means to repaint, paint over, or paint again.

So:

• måla köket = paint the kitchen
• måla om köket = repaint the kitchen / paint the kitchen a new color / paint it over

The little word om often gives the sense of again, anew, or over in this expression.

It is the same spelling, but not the same meaning.

Swedish om can mean different things depending on context:

• om = if
• om = about
• om in måla om = part of the verb, meaning something like re-, over, or again

So in this sentence, om is not if and not about. It belongs with måla to form the expression måla om.

Köket is the definite form of kök.

• ett kök = a kitchen
• köket = the kitchen

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

So:

• Vi ska måla om köket = We’re going to repaint the kitchen

If you said måla om kök, that would be ungrammatical here.

Swedish very often uses the definite form for rooms in a house when talking about a specific one that both speaker and listener understand.

So these are very natural:

• städa köket = clean the kitchen
• måla om vardagsrummet = repaint the living room
• möblera sovrummet = arrange the bedroom

Even when English and Swedish are both definite here, learners often notice that Swedish uses definite room names very consistently in these everyday situations.

In Swedish, meal names often appear without the definite ending after prepositions like efter, före, till, and so on.

So these are very common:

• efter lunch = after lunch
• före middag = before dinner
• till frukost = for breakfast

You can say efter lunchen in some contexts, but that sounds more like a specific lunch already identified in the conversation, such as after the lunch we just had.

In this sentence, efter lunch is the normal general expression.

Literally, it means after lunch.

In practice, that often places the action sometime in the afternoon, but the phrase itself is tied to the meal, not to the clock.

So:

• efter lunch = after lunch
• i eftermiddag = this afternoon
• på eftermiddagen = in the afternoon

They can overlap in real life, but they are not identical.

The sentence follows normal Swedish main-clause word order:

Vi | ska | måla om | köket | efter lunch

That is:

1. subject — Vi
2. finite verb — ska
3. infinitive verb phrase — måla om
4. object — köket
5. time expression — efter lunch

A very literal structure would be:

• We | are going to | repaint | the kitchen | after lunch

Yes, particle verbs in Swedish can sometimes split up, and that can confuse learners.

In this sentence, måla om stays together before the object:

• Vi ska måla om köket

But in other structures, the particle can appear later:

• Vi målade köket om
  This can occur, though målade om köket is often more natural in many contexts.

With pronouns, separation is especially common in some verb-particle patterns:

• Vi målade om det = We repainted it

For learners, the safest thing is to learn måla om as a unit meaning repaint, while also noticing that Swedish particle verbs do not always behave exactly like single-word verbs.

Yes. That is also grammatical.

• Vi ska måla om köket efter lunch
• Vi kommer att måla om köket efter lunch

Both can refer to the future, but ska often sounds more like a plan, intention, or arrangement.
kommer att is a more neutral future marker in many cases.

In everyday speech, ska is extremely common for planned actions, so it is very natural here.

Then Swedish uses its normal V2 word order, meaning the finite verb must come in second position:

• Efter lunch ska vi måla om köket.

Not:

• Efter lunch vi ska måla om köket.

This is a very important Swedish rule. If something other than the subject comes first, the finite verb still stays in second position.

Yes, lunch is a normal Swedish word. It is a borrowing, but it is fully established in modern Swedish and very common.

So learners should treat it as an ordinary Swedish noun:

• äta lunch = eat lunch
• efter lunch = after lunch
• på lunchen = during lunch / on the lunch break

A native speaker would usually stress the key content words:

Vi ska måla om köket efter lunch.

The main information-carrying words are typically:

• måla om
• köket
• lunch

Meanwhile vi and ska are usually less strongly stressed unless you are contrasting them with something else.

So if you are reading it aloud, do not stress every word equally. Swedish sounds more natural when the content words stand out more.
