Det andra däcket ser också dåligt ut, så verkstaden ska titta på båda i morgon.

This is because Swedish often uses double definiteness when a definite noun has an adjective before it:

• det = the definite article for a singular ett-word
• andra = the adjective
• däcket = däck
  • the definite ending -et

So det andra däcket literally has both a separate definite marker and a definite noun ending.

Also, däck is an ett-word, so the definite singular form is däcket.

It can mean either, depending on context.

• andra can mean second
• andra can also mean other

In this sentence, because the end says båda (both), a learner will often understand det andra däcket as the other tire. But grammatically, andra itself can express either idea.

Because däck is a neuter noun, and the adjective agrees with it.

Here are the forms:

• dålig = common gender singular
• dåligt = neuter singular
• dåliga = plural and definite contexts

Since däcket is singular neuter, Swedish uses dåligt:

• däcket ser dåligt ut

Compare:

• bilen ser dålig ut = the car looks bad
• däcket ser dåligt ut = the tire looks bad

This is the particle verb se ut, which means look or appear.

So:

• ser ut = looks / appears

In Swedish main clauses, the verb and its particle are often split up:

• Däcket ser dåligt ut

The basic form is:

• se ut

So you can think of the sentence structure as:

• däcket
  • ser
    • dåligt
      • ut
• the tire + looks + bad + out

Even though ut is separated, it still belongs to the verb se ut.

Because in a normal Swedish main clause, the finite verb usually comes early, and adverbs like också often come after it.

So the pattern here is:

• Det andra däcket = subject
• ser = finite verb
• också = also
• dåligt ut = complement / rest of the verb phrase

That gives:

• Det andra däcket ser också dåligt ut

This is the natural word order in Swedish.

Because it refers to a specific workshop/garage, not just any workshop.

• en verkstad = a workshop / a garage
• verkstaden = the workshop / the garage

In context, this means the repair shop or the garage that will check the tires.

In car-related contexts, verkstad often means a repair shop rather than a general workshop.

Here ska is used to talk about the future, especially something planned or expected.

So:

• verkstaden ska titta på båda i morgon
  = the garage will / is going to look at both tomorrow

It does not necessarily mean a strong obligation here. It is more like a planned future action.

Titta på literally means look at.

In this sentence, because the subject is a repair shop, it probably means something a little more practical, like:

• inspect
• check
• take a look at

The på is part of the normal expression:

• titta på något = look at something

So:

• titta på båda = look at both of them / inspect both

Without på, titta usually would not take the object in the same way.

Båda means both.

Here it refers to the two tires being discussed. Since the noun is already clear from context, Swedish does not need to repeat it.

So:

• titta på båda = look at both of them

If Swedish wanted to repeat the noun, it could say:

• titta på båda däcken = look at both tires

Because så here is a coordinating conjunction meaning so.

It joins two main clauses:

1. Det andra däcket ser också dåligt ut
2. så verkstaden ska titta på båda i morgon

After this kind of så, Swedish keeps normal main-clause word order:

• subject + finite verb

So:

• verkstaden ska ...

not:

• ska verkstaden ...

You would get inversion only if something else were moved to the front of that clause, for example:

• I morgon ska verkstaden titta på båda

Yes, you may also see imorgon.

Both spellings occur, and i morgon is a very common traditional spelling. For learners, it is good to recognize both:

• i morgon
• imorgon

They mean the same thing: tomorrow.
