Hun er både pålidelig og punktlig, fordi hun altid svarer, når jeg skriver, og fordi hun husker vores aftaler.

Både ... og means both ... and.

So:

• Hun er både pålidelig og punktlig = She is both reliable and punctual

This is a very common Danish structure for joining two equal items, especially adjectives, nouns, or verbs.

Examples:

• Han er både klog og sjov = He is both smart and funny
• Vi spiser både brød og ost = We eat both bread and cheese

Hun means she, and er is the present tense of at være (to be).

So:

• hun = she
• er = is

Together:

• Hun er = She is

This is just the normal present-tense form.

In this sentence, the adjectives come after er, so they are predicate adjectives. In Danish, predicate adjectives are often in the basic form when the subject is a common singular noun or pronoun like hun.

So:

• Hun er pålidelig
• Hun er punktlig

There is no extra ending here.

Compare:

• en pålidelig person = a reliable person
• Hun er pålidelig = She is reliable

If the subject were plural or neuter, the adjective might change:

• De er pålidelige = They are reliable
• Det er pålideligt = It is reliable

Pålidelig means reliable, dependable, or trustworthy depending on context.

In this sentence, it suggests that she can be counted on because:

• she answers when written to
• she remembers agreements

So it is not just about honesty; it is more about being someone you can rely on.

Punktlig usually means punctual or on time.

In a broader sense, it can also suggest that someone is good at keeping arrangements and doing things at the expected time.

So here it fits well with:

• hun husker vores aftaler = she remembers our appointments/agreements

It gives the idea that she is organized and respects plans.

The sentence says:

• fordi hun altid svarer, når jeg skriver
• og fordi hun husker vores aftaler

Using fordi twice makes the structure very clear: there are two separate reasons.

In English, we often do the same:

• She is reliable and punctual because she always answers when I write, and because she remembers our arrangements.

You could sometimes omit the second fordi in other contexts, but repeating it is very natural and often clearer.

Because når introduces a subordinate clause.

In Danish subordinate clauses, the word order is usually:

• conjunction + subject + adverb + verb

So:

• når jeg skriver = when I write

Not:

• når skriver jeg

That second version would sound wrong in standard Danish.

Compare:

• Main clause: Jeg skriver altid = I always write
• Subordinate clause: når jeg altid skriver = when I always write

The subject comes before the verb in subordinate clauses.

Because these are present tense verbs.

• at svare = to answer
• svarer = answers / answer
• at skrive = to write
• skriver = writes / write

In Danish, the present tense is usually formed with -r:

• at bo → bor
• at købe → køber
• at lære → lærer

So:

• hun svarer = she answers
• jeg skriver = I write / am writing

Here, når means when, in the sense of something that happens regularly or whenever it occurs.

So:

• når jeg skriver = when / whenever I write

Why not the others?

• når = when/whenever, for repeated or general situations
• da = when, for a specific past event
• hvis = if

So this sentence uses når because the meaning is something like:

• whenever I write to her, she answers

Examples:

• Når jeg ringer, tager han telefonen = When/Whenever I call, he picks up
• Da jeg ringede i går, svarede han ikke = When I called yesterday, he didn’t answer
• Hvis jeg ringer, svarer han måske = If I call, he might answer

It literally means I write, but in context it often means:

• I write to her
• I message her
• I text her

Danish often uses skrive in this broader everyday communication sense, especially in modern contexts like texting, chat, email, or messaging apps.

So in this sentence, it probably means:

• whenever I send her a message, she replies

Altid means always.

In a normal main clause, Danish often places adverbs like altid after the subject and before the main verb:

• hun altid svarer = she always answers

That is the standard position here.

Basic pattern:

• subject + adverb + verb

Examples:

• Jeg ofte læser om aftenen is not the usual main-clause order
• Jeg læser ofte om aftenen = I often read in the evening

But with some verbs and structures, adverb placement can vary depending on clause type. In this sentence, hun altid svarer is inside a subordinate clause after fordi, where the placement is natural and correct.

Vores means our.

Aftaler is the plural of aftale, which can mean:

• agreements
• arrangements
• appointments
• plans

In this sentence, vores aftaler most likely means:

• the plans we have made
• the appointments we have agreed on
• our arrangements

So it suggests she remembers what has been planned between us.

Because the speaker is talking about agreements/arrangements in general, not just one single arrangement.

• aftale = agreement / appointment / arrangement
• aftaler = agreements / appointments / arrangements

So:

• hun husker vores aftaler = she remembers our arrangements/plans

If it were singular, it would be:

• hun husker vores aftale = she remembers our agreement/appointment

Danish uses commas more systematically around subordinate clauses than English often does.

Here:

• ..., når jeg skriver, ...
• ..., og fordi hun husker vores aftaler.

The comma before når marks the subordinate clause:

• når jeg skriver

The comma before the second fordi helps separate the two reason clauses clearly.

In Danish writing, comma rules can feel more visible than in English, especially with conjunctions like:

• fordi = because
• når = when
• hvis = if
• at = that

The sentence breaks down like this:

• Hun er både pålidelig og punktlig

  • main statement

• fordi hun altid svarer

  • first reason

• når jeg skriver

  • time clause inside that reason

• og fordi hun husker vores aftaler

  • second reason

So the logic is:

She is both reliable and punctual because

1. she always answers when I write
2. she remembers our arrangements

That makes it a good example of a main clause followed by two coordinated reason clauses.

Yes. Danish often allows small stylistic variations.

For example:

• Hun er både pålidelig og punktlig, fordi hun altid svarer, når jeg skriver, og husker vores aftaler.

This removes the second fordi. It is still understandable, but the original version is clearer because it balances the two reasons nicely.

Another possibility:

• Hun er pålidelig og punktlig, for hun svarer altid, når jeg skriver, og hun husker vores aftaler.

This is a bit less formal in tone because for can mean because in a more conversational way.

The original sentence is very natural and well-structured.
