Jeg drikker kaffe i haven, selv når vejret er koldt.

Drikke is the infinitive, equivalent to to drink.

In the sentence, you need the present tense, so Danish uses drikker:

• at drikke = to drink
• jeg drikker = I drink / I am drinking

A useful thing to know is that Danish verbs do not change for different persons:

• jeg drikker
• du drikker
• han drikker
• vi drikker

The form stays the same.

It can mean either one, depending on context.

Danish often uses the simple present where English might use either:

• I drink
• I am drinking

In this particular sentence, because of selv når vejret er koldt, it sounds most naturally like a habit or a general fact:

• I drink coffee in the garden, even when the weather is cold.

So here, jeg drikker is best understood as something the speaker regularly does.

Because kaffe is being used as a mass noun, like coffee in English.

In English, you can say:

• I drink coffee

not necessarily

• I drink a coffee

Danish works the same way here:

• Jeg drikker kaffe = I drink coffee

If you wanted to mean a coffee as in one serving or one cup, Danish can say:

• en kaffe

And if you meant a specific coffee already known in context, you could say:

• kaffen = the coffee

Because Danish usually adds the definite article to the end of the noun.

So:

• have = garden
• haven = the garden

and:

• vejr = weather
• vejret = the weather

This is one of the biggest differences from English. Instead of putting the before the noun, Danish often attaches it:

• en have = a garden

• haven = the garden

• et vejr = a weather
• vejret = the weather

Also notice the two genders:

• -en often goes with common gender nouns
• -et often goes with neuter nouns

That is why you get haven but vejret.

I is the normal Danish preposition for in here, so i haven means in the garden.

That is the standard way to express being located within that space.

Compare:

• i huset = in the house
• i byen = in the city
• i haven = in the garden

For an English speaker, this usually feels natural because English also says in the garden.

Yes. Danish word order is fairly flexible, especially with adverbials like place expressions.

The original sentence:

• Jeg drikker kaffe i haven, selv når vejret er koldt.

You could also say:

• I haven drikker jeg kaffe, selv når vejret er koldt.

That gives more emphasis to i haven.

Notice what happens when something else comes first in a main clause: Danish uses verb-second word order, so the verb comes before the subject:

• I haven drikker jeg kaffe
• not I haven jeg drikker kaffe

Here, selv does not mean self. In this construction, it means even.

So:

• når = when
• selv når = even when

This is a fixed and very common pattern in Danish.

So the phrase means:

• even when the weather is cold

English speakers often first learn selv as something like self or myself/himself in certain contexts, but Danish selv also has this adverbial meaning of even or itself depending on the sentence.

Sometimes, but the nuance is a bit different.

• selv når = even when
• selvom = even though / although

In this sentence, selv når is especially natural because it suggests a repeated situation:

• whenever the weather is cold, I still drink coffee in the garden

That fits a habitual statement well.

If you said:

• Jeg drikker kaffe i haven, selvom vejret er koldt

it would still be understandable, but it sounds more like a direct contrast with a fact:

• I drink coffee in the garden, although the weather is cold

So selv når is the better choice for the idea of even on those occasions when...

Because når introduces a subordinate clause, and subordinate clauses in Danish do not use the same word order as main clauses.

In a main clause, Danish follows verb-second word order:

• Vejret er koldt

But after a conjunction like når, the clause keeps the normal subordinate order:

• når vejret er koldt

So the structure is:

• når
  • subject + verb + complement

This is very important in Danish grammar.

You can also see it with negation:

• når vejret ikke er koldt

In subordinate clauses, words like ikke usually come before the finite verb, which helps show that the word order is different from a main clause.

Because kold is agreeing with vejret, and vejr is a neuter noun.

After er, Danish adjectives still often agree with the noun they describe:

• en have er kold = a garden is cold
• et hus er koldt = a house is cold
• vejret er koldt = the weather is cold

So:

• kold = common gender singular
• koldt = neuter singular
• kolde = plural or definite forms in many contexts

Since vejret comes from et vejr, the adjective becomes koldt.

Because når is used for general, repeated, or future-related situations, while da is typically used for a single past event.

This sentence describes something habitual:

• I drink coffee in the garden even when the weather is cold

That is exactly the kind of context where Danish uses når.

Compare:

• Når vejret er koldt, bliver jeg inde.
  = When the weather is cold, I stay inside.
  general/repeated meaning

• Da vejret blev koldt, gik vi indenfor.
  = When the weather became cold, we went inside.
  one specific past event

So når is the correct choice here.

Because selv når vejret er koldt is a subordinate clause, and many Danish writers put a comma before subordinate clauses.

So this sentence is perfectly normal as written:

• Jeg drikker kaffe i haven, selv når vejret er koldt.

However, Danish comma rules allow some variation depending on comma style. In modern Danish, the comma before a subordinate clause can be omitted in some systems, so you may also see:

• Jeg drikker kaffe i haven selv når vejret er koldt.

Both can be accepted, but the version with the comma is very common and very clear for learners.

It is the normal noun for weather, but in actual usage Danish very often uses it in the definite form:

• vejret = the weather

That is similar to English, where we often say the weather rather than just weather in many sentences:

• The weather is cold
• The weather is nice

So in Danish, vejret er koldt feels very natural. You will often encounter weather expressions like:

• Vejret er godt
• Vejret er dårligt
• Vejret er varmt
• Vejret er koldt

This is a very common pattern to learn early.
