Jeg henter ny salve på apoteket, hvis forbindingen bliver våd.

Because Danish often uses the present tense for future meaning when the context already makes the future clear.

Here, the condition hvis forbindingen bliver våd shows that this is something the speaker will do if that happens, so Jeg henter ... is perfectly natural.

• Jeg henter ny salve ... = I’ll get new ointment ...
• Danish does not need a separate future form here.

You could also say Jeg vil hente ..., but that can sound a bit more like emphasis on intention or willingness. The plain present is very common and natural.

Henter comes from at hente, which usually means to fetch, to pick up, or to go and get.

In this sentence, it suggests that the speaker will go to the pharmacy and get the ointment. Depending on context, that could mean:

• buying it
• picking it up
• collecting it

So hente is often more physical and practical than just a vague get.

Because salve can be treated like a mass noun here, similar to ointment in English.

So Jeg henter ny salve means something like:

• I’ll get new ointment
• I’ll get some fresh ointment

If you said en ny salve, that would make it sound more like one new ointment product/tube/container. Without en, the focus is more on the substance itself.

Because salve is a common-gender singular indefinite noun.

In Danish, adjectives before nouns change depending on gender and definiteness. Here:

• en ny salve / ny salve = common gender singular indefinite
• if it were neuter, you would often add -t, for example et nyt ...

So ny is the correct form with salve.

På apoteket is the normal idiomatic way to say at the pharmacy.

In Danish, på is often used with places like shops, institutions, and workplaces when talking about being there as a destination or location in a general sense.

• på apoteket = at the pharmacy
• i apoteket = in the pharmacy, physically inside it

So in this sentence, på apoteket is the natural everyday choice.

Apoteket is the definite form: the pharmacy.

Danish often uses the definite form when the place is understood from the situation, even if it has not been mentioned earlier. In English we also often say the pharmacy in the same way.

• et apotek = a pharmacy
• apoteket = the pharmacy

Here it sounds like a normal, known type of place the speaker would go to.

It is the definite article attached to the noun.

• forbinding = bandage / dressing
• forbindingen = the bandage / the dressing

Unlike English, Danish usually adds the definite article to the end of the noun instead of putting a separate word like the in front.

Because bliver våd means gets wet or becomes wet, while er våd means is wet.

That is an important difference:

• Hvis forbindingen bliver våd = If the dressing gets wet
• Hvis forbindingen er våd = If the dressing is wet

The original sentence focuses on the dressing becoming wet.

Because it agrees with forbindingen, which is singular common gender.

In predicative position (after verbs like er or bliver), Danish adjectives still show agreement:

• common singular: våd
• neuter singular: vådt
• plural: våde

So:

• forbindingen bliver våd = correct
• if the subject were neuter, it would be vådt

Because hvis introduces a subordinate clause, and subordinate clauses in Danish normally have subject before verb.

So:

• hvis forbindingen bliver våd = correct subordinate clause order

This is different from main-clause word order, where Danish often follows the V2 rule.

Then the main clause has inversion:

• Hvis forbindingen bliver våd, henter jeg ny salve på apoteket.

Notice that it is henter jeg, not jeg henter, because when something other than the subject comes first in a Danish main clause, the finite verb usually comes before the subject.

Because hvis forbindingen bliver våd is a subordinate clause, and Danish normally separates subordinate clauses with a comma.

So the comma helps mark the structure:

• main clause: Jeg henter ny salve på apoteket
• subordinate clause: hvis forbindingen bliver våd

This is very standard in written Danish.
