Kan du ställa upp och hjälpa oss imorgon?

Because this is a yes/no question. In Swedish, yes/no questions usually begin with the finite verb first, then the subject:

• Du kan hjälpa oss. = You can help us.
• Kan du hjälpa oss? = Can you help us?

So Kan du ... ? is the normal question pattern.

Here ställa upp means something like pitch in, show up for someone, or be willing to help out.

It is a very common Swedish expression, and its meaning is not the same as the literal meanings of ställa and upp taken separately. So it is best to learn ställa upp as one unit.

In this sentence, it adds a sense of being willing to come through and help.

Because kan is a modal verb. After modal verbs in Swedish, the next verb is normally in the infinitive without att.

For example:

• Jag kan komma. = I can come.
• Hon vill hjälpa. = She wants to help.

So kan du ställa upp och hjälpa oss is completely normal.

Because kan applies to both of them. The structure is basically:

Kan du [ställa upp] och [hjälpa oss] imorgon?

So the sentence means that the person is being asked whether they can do both parts of the action: be willing to step in and help us.

This is very natural in Swedish. English does the same thing: Can you come and help us tomorrow?

Because oss is the object form of we.

Compare:

• vi = we
• oss = us

Since hjälpa takes a direct object, Swedish uses oss:

• hjälpa oss = help us

Just like English says help us, not help we.

Yes. In Swedish, hjälpa usually takes a direct object:

• hjälpa mig = help me
• hjälpa henne = help her
• hjälpa oss = help us

So Swedish does not need an extra word like to or with in this basic structure.

Yes. Both imorgon and i morgon are used.

• imorgon is very common in modern writing.
• i morgon is also correct.

Both mean tomorrow. A learner should recognize both spellings.

Yes. Swedish time expressions are fairly movable.

For example, you could also say:

• Kan du ställa upp och hjälpa oss imorgon?
• Kan du imorgon ställa upp och hjälpa oss?

The version with imorgon at the end sounds very natural and neutral here.

It sounds normal and polite enough in everyday Swedish, especially if you know the person.

Swedish often sounds more direct than English because it does not always add words like please. If you want to make it softer, you could add:

• snälla
• möjligen
• a softer tone of voice

For example:

• Kan du snälla ställa upp och hjälpa oss imorgon?

But the original sentence is already perfectly natural.

Yes, you could just say Kan du hjälpa oss imorgon?

Adding ställa upp gives a slightly different nuance. It suggests:

• Can you be available for us?
• Can you step in?
• Can you do us a favor and help out?

So ställa upp adds a sense of support, willingness, or coming through when needed.

Yes, it is a particle verb, and the particle upp can separate from the verb in some sentence patterns.

For example:

• infinitive: ställa upp
• present tense statement: Du ställer upp.
• question: Ställer du upp?

So in the sentence Kan du ställa upp ... ?, the words stay together because ställa upp is in the infinitive after kan.
