Om du har ont i halsen, borde du dricka te.

Om means if in this sentence.

So:

• Om du har ont i halsen = If you have a sore throat / If your throat hurts

A useful thing to remember is:

• om = if / whether
• när = when

So if the situation is conditional, Swedish uses om.

Ha ont is a very common Swedish expression meaning to be in pain or to hurt.

Literally, har ont means have pain, but in natural English we usually translate it as:

• have pain
• be hurting
• have a sore ...
• ... hurts

Examples:

• Jag har ont i huvudet = I have a headache / My head hurts
• Hon har ont i ryggen = Her back hurts
• Vi har ont i magen = We have a stomach ache

So du har ont i halsen is the normal Swedish way to say that your throat hurts.

Ont means pain or painfully, depending on the expression. In ha ont, it is part of a fixed phrase.

You will often see:

• ha ont = to be in pain / to hurt
• det gör ont = it hurts

Compare:

• Jag har ont i foten = My foot hurts
• Det gör ont = It hurts

So in this sentence, ont is not standing alone with a simple one-word English equivalent; it works as part of the expression ha ont.

Because Swedish usually uses the definite form with body parts in expressions like this.

So:

• hals = throat / neck
• halsen = the throat

In Swedish, it is natural to say:

• ont i halsen
• ont i huvudet
• ont i ryggen
• ont i magen

Even though English often says a sore throat, Swedish prefers the structure pain in the throat.

So i halsen is the normal idiomatic form.

It can mean either, depending on context.

• hals can mean neck
• it can also mean throat

In the expression ont i halsen, it normally means throat, so the whole phrase means to have a sore throat.

Context usually makes the meaning clear.

This is because Swedish has V2 word order in main clauses.

When a sentence starts with something other than the subject—here, the subordinate clause Om du har ont i halsen—the finite verb in the main clause comes before the subject.

So the structure is:

• Om du har ont i halsen, borde du dricka te

Not:

• Om du har ont i halsen, du borde dricka te

This is very important in Swedish.

Compare:

• Du borde dricka te = You should drink tea
• I dag borde du dricka te = Today, you should drink tea
• Om du har ont i halsen, borde du dricka te = If you have a sore throat, you should drink tea

After an introductory element, the verb moves into second position.

Borde means should or ought to.

It gives advice or a recommendation, not a strong command.

So:

• Du borde dricka te = You should drink tea

It is weaker than:

• du måste dricka te = you must drink tea

And often more like advice than:

• du ska dricka te = you will / are supposed to drink tea

So borde is a good choice here because the sentence sounds like advice.

Because after a modal verb like borde, Swedish normally uses the infinitive without att.

So:

• du borde dricka te
• jag kan simma
• hon vill gå
• vi måste åka

Not:

• du borde att dricka te

This is similar to English, where we also say:

• you should drink tea

not

• you should to drink tea

Because te here is being used as an uncountable substance, just like tea in English.

So:

• dricka te = drink tea

This is the general idea of tea as a drink, not a tea as one serving.

If you wanted to talk about one tea, in a café situation for example, Swedish could use:

• ett te = a tea

But in advice like this, dricka te is the natural form.

Not always. In modern Swedish, the comma before the main clause is often optional, especially in shorter sentences.

So both of these can be seen:

• Om du har ont i halsen borde du dricka te.
• Om du har ont i halsen, borde du dricka te.

The comma can make the sentence easier to read, but it is not always required.

No. That would not be correct Swedish.

You need the expression ha ont, not vara ont.

Correct:

• Om du har ont i halsen ...

Incorrect:

• Om du är ont i halsen ...

So when talking about pain in Swedish, remember:

• ha ont = the normal expression

You could say it, but it sounds less natural in this context.

Swedish usually does not use possessives like din, min, hans with body parts when it is already obvious whose body part is meant.

So the natural version is:

• du har ont i halsen

rather than:

• du har ont i din hals

This is a common difference from English.

It is neutral, everyday Swedish.

• du is the normal Swedish word for you
• borde sounds like ordinary advice
• the whole sentence sounds natural in conversation, writing, or simple health advice

So this is not especially formal or especially casual—it is just standard Swedish.
