Oavsett om det regnar eller är soligt, går jag till jobbet.

Yes. Oavsett om is a very common expression meaning regardless of whether.

It introduces two alternatives:

• det regnar = it is raining
• är soligt = it is sunny

So the pattern is:

oavsett om X eller Y ...
= regardless of whether X or Y ...

You can use it in many similar sentences:

• Oavsett om du kommer tidigt eller sent, är du välkommen.
• Oavsett om det är dyrt eller billigt, måste vi köpa det.

It is best learned as a chunk: oavsett om.

In Swedish, weather expressions often use det as a dummy subject, just like English uses it in it rains.

So:

• det regnar = it is raining
• det snöar = it is snowing
• det blåser = it is windy / it is blowing

The det does not refer to a real thing. It is just required grammatically.

Good question. The full version would be:

Oavsett om det regnar eller det är soligt, går jag till jobbet.

But Swedish often avoids repeating words that are already understood. So the second det is omitted:

... det regnar eller är soligt ...

This is very natural. English does something similar:

• whether it rains or is sunny

So the second part is understood as:

• (det) är soligt

This is because of the Swedish V2 rule: in a main clause, the finite verb usually comes in the second position.

The main clause here is:

• går jag till jobbet

Why is the verb first? Because the sentence begins with another element:

• Oavsett om det regnar eller är soligt = first element
• går = finite verb in second position
• jag = subject after the verb

So Swedish word order is:

[fronted element], [verb], [subject] ...

Compare:

• Jag går till jobbet.
• På måndagar går jag till jobbet.
• Oavsett om det regnar eller är soligt, går jag till jobbet.

This verb-before-subject order is very important in Swedish.

Yes, essentially. Oavsett om det regnar eller är soligt functions like a subordinate clause or subordinate clause phrase that sets the condition/frame for the main clause.

A useful thing to notice is:

• the first part comes before the main clause
• then the main clause follows with V2 word order

So even if you do not analyze it deeply, the practical lesson is:

When this kind of phrase comes first, the main clause often starts with verb + subject:

• ..., går jag ...

In normal writing, the comma is common and helpful here because the opening clause is fairly long:

Oavsett om det regnar eller är soligt, går jag till jobbet.

The comma makes the structure easier to read. In some contexts, Swedish commas can be more flexible than English commas, but in a sentence like this, using the comma is very natural and recommended.

Solig means sunny. Here it appears as soligt because Swedish often uses the -t form when the adjective is used in expressions with det är:

• det är soligt
• det är kallt
• det är varmt

This is the neuter singular form of the adjective.

So:

• solig dag = sunny day
• ett soligt väder = sunny weather
• det är soligt = it is sunny

In weather expressions, this -t form is very common.

Because gå till means go to.

So:

• gå till jobbet = go to work
• gå till skolan = go to school
• gå till affären = go to the store

The preposition till shows movement toward a destination.

Also, jobbet is the definite form of jobb:

• ett jobb = a job
• jobbet = the job

In Swedish, gå till jobbet is the normal idiomatic way to say go to work.

Yes, grammatically you could, but it sounds more formal or less everyday.

Compare:

• gå till jobbet = most common in everyday speech
• gå till arbetet = more formal, more written, or less conversational

So if you are speaking naturally in everyday Swedish, jobbet is usually the better choice.

Yes. A common alternative is:

Vare sig det regnar eller är soligt, går jag till jobbet.

This also means whether it rains or it is sunny / regardless of whether...

The difference is mainly style:

• oavsett om = very common and straightforward
• vare sig ... eller ... = also common, but feels a little more formal or literary to some learners

Both are correct.

Yes, absolutely:

Oavsett om det är regnigt eller soligt, går jag till jobbet.

This version uses two adjectives:

• regnigt = rainy
• soligt = sunny

Your original sentence uses:

• det regnar = it is raining
• är soligt = it is sunny

So the difference is mainly in structure:

• det regnar focuses on the action/weather event
• det är regnigt describes the weather as a condition

Both are natural, though det regnar can feel a little more vivid and immediate.

They are all in the present tense.

• regnar = present tense of regna
• är = present tense of vara
• går = present tense of gå

In this sentence, the present tense expresses a general habit or repeated action, not just something happening right now.

So går jag till jobbet means something like:

• this is what I do
• this is my routine
• this remains true under those weather conditions

This is very similar to how English uses the present simple for habits.

A learner-friendly approximation is:

OH-ah-VSET

A few helpful notes:

• the v is pronounced
• the stress is on the last part: -sett
• the tt gives a short final consonant sound

A rough breakdown:

• oa-
• vsett

But it is best to hear it from native audio, because connected Swedish speech can make it sound smoother than the spelling suggests.

It is completely natural. It sounds like standard, correct Swedish.

It has:

• a very common expression: oavsett om
• natural weather wording: det regnar / är soligt
• correct Swedish main-clause word order: går jag
• an everyday phrase: till jobbet

So this is a very good model sentence for learners.
