Vasen ser ut som om den är färdig.

Because vasen is the definite form: the vase.

• en vas = a vase
• vasen = the vase

So the sentence is talking about a specific vase, not just any vase.

Se ut is a very common Swedish particle verb meaning to look, to appear, or to seem.

So:

• Vasen ser ut ... = The vase looks ...

Be careful: se by itself usually means to see, but se ut has a different meaning.

Examples:

• Hon ser trött ut. = She looks tired.
• Det ser bra ut. = It looks good.

Because se ut is a particle verb, and in Swedish these are often written as two words when the verb is conjugated.

So:

• infinitive: se ut
• present tense: ser ut
• past tense: såg ut

Examples:

• att se ut = to look
• den ser ut = it looks
• den såg ut = it looked

This is normal and not something unusual about this sentence.

Som om means as if.

So:

• ser ut som om den är färdig = looks as if it is finished

It introduces a comparison with how something appears, not necessarily what is definitely true.

Compare:

• Han pratar som om han visste allt. = He talks as if he knew everything.
• Det ser ut som om det ska regna. = It looks as if it’s going to rain.

Because Swedish normally needs a subject in that clause, just like English does in as if it is finished.

Here, den refers back to vasen.

• vasen is an en-word
• so the pronoun is den

If the noun were a t-word, you would use det instead.

Examples:

• bordet ... det
• vasen ... den

So:

• Vasen ser ut som om den är färdig.
• Bordet ser ut som om det är nytt.

Because vas is an en-word in Swedish:

• en vas
• therefore: den

Swedish third-person pronouns for things often match the grammatical gender of the noun:

• en-word → den
• ett-word → det

So since it is en vas, you say den är färdig.

Because färdig agrees with the noun it describes.

Here, the word refers to vasen, which is an en-word and singular, so the adjective is:

• färdig

Compare:

• en vas är färdig
• ett arbete är färdigt
• de är färdiga

So the forms are:

• färdig for common gender singular
• färdigt for neuter singular
• färdiga for plural

Here färdig means something like finished, done, or ready.

With an object like a vase, finished is usually the most natural interpretation: the vase appears to be complete.

Depending on context, färdig can mean slightly different things:

• Maten är färdig. = The food is ready.
• Jag är färdig. = I’m finished / I’m done.
• Vasen är färdig. = The vase is finished / completed.

Not necessarily.

Ser ut som om is about appearance, not certainty. It means that based on what the speaker sees, the vase seems finished.

So the speaker is not directly stating a fact like:

• Vasen är färdig. = The vase is finished.

Instead, they are saying:

• Vasen ser ut som om den är färdig. = The vase looks as if it is finished.

That leaves room for uncertainty.

Yes, absolutely. That is a very natural alternative.

• Vasen ser färdig ut. = The vase looks finished.
• Vasen ser ut som om den är färdig. = The vase looks as if it is finished.

The shorter version is often more direct and more everyday.
The longer version can sound a little more explicit or cautious, because it literally says looks as if it is finished.

Both are correct.

Yes. Som om introduces a subordinate clause.

In this sentence, the word order looks normal because there is no adverb in the clause:

• den är färdig

But if you add an adverb like inte, you can see the subordinate-clause pattern more clearly:

• Vasen ser ut som om den inte är färdig.

Notice that inte comes before the verb är in the subordinate clause.

That is a useful Swedish pattern to remember.

Sometimes, especially in spoken or informal Swedish, people may say som att. But som om is the standard and safest choice here.

So for learners, som om is the best version to use:

• Vasen ser ut som om den är färdig.

That is fully correct and natural.
