Om ni vill, kan vi bjuda moster och faster på te ur samma termos i övermorgon.

Om means if, so Om ni vill means If you want or If you’d like.

It introduces a condition for the main clause:

• Om ni vill = if you want
• kan vi bjuda ... = we can offer/invite ...

So the whole structure is basically:

• If you want, we can ...

This is because of Swedish V2 word order.

In a normal main clause, you would say:

• Vi kan bjuda moster och faster på te.
• We can offer auntie and auntie on dad’s side tea.

But when something else comes first—here, the conditional clause Om ni vill—the finite verb must come before the subject in the main clause:

• Om ni vill, kan vi ...

So:

• first position: Om ni vill
• second position: kan
• then subject: vi

This is a very common Swedish pattern.

Ni is the plural form of you.

So it is used when speaking to:

• more than one person, or
• sometimes one person in a polite/formal way

In modern everyday Swedish, ni most often simply means you all / you guys / you two / you people.

So in this sentence, the most likely meaning is:

• If you all want, we can ...

Here bjuda means something like:

• offer
• treat
• invite (depending on context)

A very common Swedish pattern is:

• bjuda någon på något

which means:

• offer someone something
• treat someone to something

So:

• bjuda moster och faster på te = offer auntie and auntie on dad’s side tea / treat them to tea

Depending on context, it can also sound a bit like:

• invite them for tea

The preposition på is part of the fixed expression bjuda någon på något.

So you should learn it as a whole pattern:

• bjuda någon på kaffe
• bjuda någon på middag
• bjuda någon på glass

It does not translate word-for-word neatly into English, but the meaning is:

• treat someone to
• offer someone

So på is required here because of the verb pattern, not because it literally means on.

Swedish makes a distinction that English usually does not:

• moster = your mother’s sister
• faster = your father’s sister

English uses aunt for both, but Swedish is more specific.

Related family words:

• morbror = mother’s brother
• farbror = father’s brother

So this sentence specifically mentions two different kinds of aunt.

In Swedish, family words are often used without an article and can behave almost like names or titles, especially when the relationship is clear from context.

So:

• bjuda moster och faster can sound natural if everyone knows which moster and faster are meant.

English usually needs something like:

• our aunt and our other aunt
• Auntie and Auntie
• or just names

Swedish can leave this more implicit.

If you wanted to be more explicit, you could say things like:

• vår moster och vår faster
• min moster och min faster

But the shorter version is perfectly possible in context.

Ur means out of or from, especially when something comes out of a container.

So:

• ur samma termos = from the same thermos

Why ur and not från?

• ur is often used when something is taken or poured out of something
• från is more general: from

Because tea is being served from a thermos, ur is very natural here.

Examples:

• dricka ur en kopp = drink from a cup
• hälla kaffe ur en termos = pour coffee from a thermos

With samma (same), Swedish normally uses the noun in its basic form:

• samma dag = the same day
• samma bok = the same book
• samma termos = the same thermos

So samma itself already gives the noun a definite meaning, and you usually do not add the normal definite ending.

That is why:

• samma termos is correct
• termosen would usually not be used here

I övermorgon is the normal modern expression for the day after tomorrow.

So:

• i morgon = tomorrow
• i övermorgon = the day after tomorrow

You may also see or hear övermorgon without i, but i övermorgon is very common and standard.

It works as a time expression in the sentence:

• ... i övermorgon = ... the day after tomorrow

Yes. Swedish is fairly flexible with time expressions.

The given sentence says:

• Om ni vill, kan vi bjuda moster och faster på te ur samma termos i övermorgon.

But you could also say:

• I övermorgon kan vi bjuda moster och faster på te ur samma termos, om ni vill.
• Om ni vill, kan vi i övermorgon bjuda moster och faster på te ur samma termos.

The exact placement changes the emphasis a little, but the basic meaning stays the same.

The comma is natural and helpful here, because Om ni vill is an introductory clause.

So:

• Om ni vill, kan vi ...

In Swedish, commas in this kind of sentence are often a matter of style more than strict necessity in everyday writing. Many people would write it with the comma, especially because it makes the sentence easier to read.

So the comma is a good choice here, even if you may sometimes see similar sentences written without one.

Yes, it can.

Depending on context, bjuda någon på te can suggest:

• offering someone tea
• treating someone to tea
• having them over for tea

So the phrase has a slightly broader range than a single English translation.

In this sentence, because of ur samma termos, it strongly suggests actually serving them tea from that thermos. But the social idea of having them for tea is also still there.
