Om du går åt fel håll, kommer du inte till stationen.

Om means if when it introduces a condition.

So:

• Om du går åt fel håll = If you go in the wrong direction
• om introduces the situation or condition
• the rest of the sentence tells you the result of that condition

In Swedish, om is the normal word for if in sentences like this.

Går is the present tense of gå, which means to go / to walk.

Because the subject is du = you, Swedish uses the present-tense verb form:

• jag går = I go / I am going
• du går = you go / you are going

Unlike English, Swedish does not change the verb for different persons in the present tense. So jag går, du går, vi går, de går all use går.

In this sentence, åt is part of the expression gå åt ... håll, which means go in a ... direction.

So:

• gå åt rätt håll = go in the right direction
• gå åt fel håll = go in the wrong direction

You should think of åt here less as a word to translate by itself and more as part of a fixed pattern.

Fel håll is a common idiomatic expression meaning the wrong direction.

Swedish often leaves out the article in set phrases like this. So even though English says the wrong direction, Swedish naturally says:

• åt fel håll

not usually something heavier or more explicit.

Also, håll here means direction, not just side in a literal sense.

Yes, fel riktning is possible and also means wrong direction.

But there is a small difference in feel:

• åt fel håll is very common and idiomatic in everyday speech
• i fel riktning sounds a bit more formal or abstract

So in this sentence, går åt fel håll sounds very natural.

This is because Swedish uses verb-second word order in main clauses.

The sentence begins with a subordinate clause:

• Om du går åt fel håll

After that comes the main clause. In a Swedish main clause, the finite verb usually has to come in the second position. So you get:

• kommer du inte till stationen

not:

• du kommer inte till stationen

That would be possible only if the sentence started directly with the main clause:

• Du kommer inte till stationen om du går åt fel håll.

Both full sentences are correct, but the word order changes depending on what comes first.

In Swedish main clauses, inte usually comes after the finite verb.

So:

• kommer du inte till stationen

This is normal Swedish word order.

Compare:

• Du kommer inte till stationen.
• Han går inte dit.

But in subordinate clauses, inte usually comes before the finite verb. For example:

• ... om du inte går rätt

So learners often have to pay attention to the difference between:

• main clause word order
• subordinate clause word order

No. Here kommer is the ordinary verb komma = to come / to get / to arrive.

So:

• kommer du inte till stationen means you do not get to the station or you do not arrive at the station

It is not the future construction kommer att.

For example:

• Du kommer att gå dit = You will go there

That is different from:

• Du kommer dit = You get there / You arrive there

So in your sentence, kommer is a full verb meaning something like reach / get to / arrive at.

Till means to, especially when talking about movement toward a place.

So:

• komma till stationen = get to the station / arrive at the station

This is the normal preposition with destinations.

Examples:

• gå till skolan = go to school
• åka till Stockholm = travel to Stockholm
• komma till stationen = get to the station

Stationen is the definite form, meaning the station.

Swedish usually puts definiteness on the noun itself:

• en station = a station
• stationen = the station

Since the English meaning is the station, Swedish uses stationen.

Literally, gå often means walk, but in many contexts it can also be understood more generally as go.

In this sentence, it suggests moving on foot or moving in a direction, but the important idea is the direction you are taking.

So Om du går åt fel håll can be understood as:

• If you walk in the wrong direction
• If you go in the wrong direction

The exact English translation depends on context.

Yes. A very common alternative is:

• Du kommer inte till stationen om du går åt fel håll.

This means the same thing.

The difference is mostly about emphasis:

• Om du går åt fel håll, kommer du inte till stationen.
  starts with the condition
• Du kommer inte till stationen om du går åt fel håll.
  starts with the result

Both are natural.

The comma separates the conditional clause from the main clause:

• Om du går åt fel håll, = subordinate clause
• kommer du inte till stationen. = main clause

In Swedish, commas in short sentences like this are sometimes optional depending on style, but many writers use one here because it makes the structure clearer.

So the comma helps readability, even though the grammar works either way.

The sentence has two parts:

1. Om du går åt fel håll
   = conditional subordinate clause
   = If you go in the wrong direction

2. kommer du inte till stationen
   = main clause
   = you do not get to the station

A useful pattern to remember is:

• Om + clause, verb + subject + inte + rest

So this sentence is a good example of both:

• an om-clause
• Swedish verb-second word order in the main clause
