Vi skojar under keramikkursen.

Skoja is the infinitive, meaning to joke / to kid around / to fool around.

In the sentence, the verb is conjugated in the present tense, so skoja becomes skojar:

• att skoja = to joke
• vi skojar = we joke / we are joking

A useful thing to remember: in Swedish, the present tense form is the same for all persons:

• jag skojar
• du skojar
• han/hon skojar
• vi skojar

So skojar is the correct finite verb form here.

Because Swedish does not normally use a separate be + -ing form the way English does.

Vi skojar can mean:

• we joke
• we are joking
• we’re joking around

The exact meaning depends on context.

This is very common in Swedish. For example:

• Jag läser. = I read / I am reading
• De jobbar. = They work / They are working

So vi skojar is perfectly normal without any extra word for are.

They are close, but not always identical.

• skoja often means joke around, kid around, or mess around in a light, playful way.
• skämta is often a bit more directly to joke.

In many everyday situations, they overlap a lot. But skoja can feel slightly more informal and playful.

So:

• Vi skojar. = We’re joking around / kidding around
• Vi skämtar. = We’re joking

Both are common, but skojar can sound a little more casual.

Here under means during.

So under keramikkursen means during the pottery course / during pottery class.

This is a common use of under in Swedish:

• under lektionen = during the lesson
• under sommaren = during the summer
• under mötet = during the meeting

So even though under can also mean under/below in other contexts, here it is purely about time.

Yes, you often could, but the nuance changes slightly.

• under keramikkursen focuses on during the time of the class/course
• på keramikkursen focuses more on at/in the class/course

So:

• Vi skojar under keramikkursen = We joke around during the pottery class
• Vi skojar på keramikkursen = We joke around in/at pottery class

In everyday speech, på keramikkursen is often very natural when talking about what happens in a class. Under is a bit more explicitly temporal.

Because Swedish loves compound nouns.

Keramikkursen is built from:

• keramik = ceramics / pottery
• kurs = course / class
• -en = the (definite ending)

So:

• keramikkurs = ceramics course / pottery class
• keramikkursen = the ceramics course / the pottery class

In English, we usually write these as separate words, but Swedish normally combines them into one word.

This is a very important Swedish pattern:

• svenska + lärare → svensklärare
• sommar + lov → sommarlov
• kaffe + kopp → kaffekopp

The ending -en is the definite article attached to the noun.

In English, you put the before the noun:

• the course

In Swedish, you often add the definiteness to the end:

• kurs = course
• kursen = the course

So:

• en keramikkurs = a pottery course
• keramikkursen = the pottery course

In this sentence, Swedish uses the definite form because it is referring to a specific course/class, not just any pottery course.

It can mean either, depending on context.

In Swedish, kurs is a broader word than English course sometimes feels. It can refer to:

• a full course over time
• a class someone attends
• a training course

So keramikkursen could be understood as:

• the pottery course
• the pottery class

The best English choice depends on the situation.

This sentence has standard Swedish main-clause word order:

• Vi = subject
• skojar = verb
• under keramikkursen = time expression

So the basic pattern is:

subject + verb + other information

That gives:

Vi skojar under keramikkursen.

You can also move the time expression to the front:

Under keramikkursen skojar vi.

That is also correct, but then Swedish keeps the verb in second position. This is part of the famous Swedish V2 rule.

So notice:

• Vi skojar under keramikkursen.
• Under keramikkursen skojar vi.

Both are correct, but the second one emphasizes during the pottery class a bit more.

A rough approximation is:

• skojar ≈ SKOY-ar
• keramikkursen ≈ she-ra-MEEK-koor-sen

A few notes:

• In skojar, the sk is a normal hard sk sound because it comes before o.
• In keramik, the k before e is pronounced as a soft sound, which is why an English speaker may hear something like sh.
• Swedish compound words often keep their parts clear in pronunciation, so keramik + kursen is still fairly easy to hear once you know the pieces.

These are only rough English-friendly guides, but they can help you get close.
