Initiativet ska utvärderas imorgon.

Because initiativet is the definite form: the initiative.

The basic noun is ett initiativ = an initiative.
Since it is an ett-word (a neuter noun), the definite ending is -et:

• ett initiativ = an initiative
• initiativet = the initiative

In Swedish, the is often added as an ending instead of being a separate word.

You have to learn the noun together with its gender: ett initiativ.

Swedish nouns are usually either:

• en-words
• ett-words

Initiativ happens to be an ett-word, so:

• ett initiativ
• initiativet

Unfortunately, there is not always a reliable rule you can guess from, so it is best to memorize nouns with en or ett from the beginning.

Here ska means something like will, is going to, or is scheduled to.

So Initiativet ska utvärderas imorgon means that the evaluation is expected or planned to happen tomorrow.

A useful point: ska can sometimes mean must / should in other contexts, but here it is most naturally understood as a planned future event.

Because ska is a modal verb, and modal verbs in Swedish are followed by the infinitive without att.

So you get:

• ska utvärdera = will evaluate
• ska utvärderas = will be evaluated

This is similar to English, where we say will evaluate, not will to evaluate.

The -s makes the verb passive.

• utvärdera = to evaluate
• utvärderas = to be evaluated

So:

• Någon ska utvärdera initiativet imorgon = Someone will evaluate the initiative tomorrow
• Initiativet ska utvärderas imorgon = The initiative will be evaluated tomorrow

This -s passive is very common in Swedish.

In this sentence, utvärderas is best understood as a passive infinitive after ska.

That is why the structure is:

• ska
  • utvärderas

Even though -s forms can sometimes look like present tense passive in other contexts, after ska the meaning is clearly will be evaluated.

Yes, it is a passive sentence.

The focus is on the initiative, not on who does the evaluation.

Passive:

• Initiativet ska utvärderas imorgon.

Possible active version:

• Någon ska utvärdera initiativet imorgon. = Someone will evaluate the initiative tomorrow.
• Gruppen ska utvärdera initiativet imorgon. = The group will evaluate the initiative tomorrow.

Swedish often uses the passive when the doer is unknown, unimportant, or simply not mentioned.

Yes. Imorgon can be moved, and the sentence is still correct.

For example:

• Initiativet ska utvärderas imorgon.
• Imorgon ska initiativet utvärderas.

Both are natural. The second version puts more emphasis on tomorrow.

A very important Swedish rule shows up here: the finite verb usually stays in second position in main clauses. That is why:

• Imorgon ska initiativet utvärderas

and not:

• Imorgon initiativet ska utvärderas

Yes. Both spellings exist:

• imorgon
• i morgon

They mean the same thing: tomorrow.

In modern everyday Swedish, imorgon as one word is very common.

Yes, that is also correct.

• Initiativet ska utvärderas imorgon
• Initiativet kommer att utvärderas imorgon

Both can mean The initiative will be evaluated tomorrow, but there is a small nuance:

• ska often sounds like a plan, schedule, or arrangement
• kommer att is often a more neutral future statement or prediction

In this sentence, ska works very well because it sounds like the evaluation is planned.

Because Swedish usually puts the definite article at the end of the noun.

So instead of a separate word like English the, Swedish often uses an ending:

• ett initiativ = an initiative
• initiativet = the initiative

This is one of the biggest differences between English and Swedish noun grammar.
