Jeg har tillid til hende, for hun er både grundig, hjælpsom og pålidelig.

Because tillid is a noun, and the expression at have tillid til nogen is a very common way to say to trust someone / to have confidence in someone.

So the structure is:

• jeg har = I have
• tillid = trust / confidence
• til hende = in her / toward her

Danish also has another common way to say this:

• Jeg stoler på hende. = I trust her.

The two are very close in meaning, but have tillid til can sound a bit like have confidence in, while stole på is often the more direct everyday trust.

Because tillid normally takes the preposition til when you say who you trust.

So you say:

• tillid til hende
• tillid til ham
• tillid til dem

This is just the standard pattern you need to learn as a chunk:

• at have tillid til nogen

It is similar to how English often has fixed combinations like believe in, depend on, or listen to.

Because Danish distinguishes between subject and object pronouns.

• hun = she
• hende = her

In the first clause, she comes after the preposition til, so Danish uses the object form:

• til hende = to/in her

In the second clause, she is the subject of er, so Danish uses the subject form:

• hun er = she is

So this is exactly like English:

• I trust her, because she is...

Here for means because.

So:

• ..., for hun er... = ..., because she is...

It is similar to fordi, but there is an important grammar difference:

• After for, Danish keeps normal main clause word order.
• After fordi, Danish often uses subordinate clause word order.

Compare:

• Jeg har tillid til hende, for hun er grundig.
• Jeg har tillid til hende, fordi hun er grundig.

Both are natural. But for is often a little more explanatory or written in tone, while fordi is the more common everyday word for because.

Because for is a coordinating conjunction, not a subordinating one.

That means the clause after for behaves like a normal main clause:

• hun er grundig

So the order stays:

• subject + verb = hun er

This is different from Danish sentences where another element is placed first and causes inversion, such as:

• I dag er hun grundig.

But after for, there is no inversion.

Because tillid is being used as an uncountable or abstract noun here, much like trust or confidence in English.

So Danish says:

• Jeg har tillid til hende.

Not:

• Jeg har en tillid til hende. in this meaning

Using en here would sound unnatural in ordinary Danish. The expression is fixed as have tillid til.

Både ... og means both ... and.

In this sentence:

• hun er både grundig, hjælpsom og pålidelig

it means something like:

• she is both thorough, helpful, and reliable

Even though English often prefers both A and B, Danish can use både before a longer list too. So with three qualities, it still works naturally.

You can think of både as emphasizing that several positive qualities all apply at once.

Because they are predicate adjectives after er.

In Danish, adjectives after to be often agree with the subject, but with a singular personal subject like hun, the basic form is used:

• hun er grundig
• hun er hjælpsom
• hun er pålidelig

You would see different forms in other situations, for example:

• et grundigt arbejde = a thorough piece of work
• de er grundige = they are thorough

So here the basic dictionary form is the correct one.

They are all positive character descriptions:

• grundig = thorough, careful, methodical
• hjælpsom = helpful
• pålidelig = reliable, dependable

A learner might notice that this is not just random praise. Together, these adjectives explain why the speaker trusts her:

• she works carefully,
• she helps others,
• and she can be relied on.

So the second clause gives the reason for the trust in the first clause.

Yes, absolutely.

• Jeg har tillid til hende = I have confidence in her / I trust her
• Jeg stoler på hende = I trust her

Both are natural. The main difference is style and emphasis:

• have tillid til can sound a little more formal or thoughtful
• stole på is very common and direct in everyday speech

So this sentence could also be:

• Jeg stoler på hende, for hun er både grundig, hjælpsom og pålidelig.

That would still be perfectly good Danish.

Because the sentence contains two full clauses:

• Jeg har tillid til hende
• hun er både grundig, hjælpsom og pålidelig

They are joined by for, and Danish normally puts a comma between those two clauses.

There are also commas inside the list of adjectives:

• grundig, hjælpsom og pålidelig

That is just standard list punctuation.

Both are used, but fordi is usually more common in everyday spoken Danish.

So in conversation, many speakers might more naturally say:

• Jeg har tillid til hende, fordi hun er både grundig, hjælpsom og pålidelig.

Using for is still completely correct and natural, but it can sound a little more deliberate, explanatory, or slightly more written depending on context.

Yes. Danish allows some movement for emphasis, although the original version is the most neutral.

For example:

• Hende har jeg tillid til, for hun er både grundig, hjælpsom og pålidelig.

This puts extra focus on hende. It is grammatical, but it sounds more marked than the original.

So if you are learning, the safest neutral pattern is the original one:

• Jeg har tillid til hende, for hun er både grundig, hjælpsom og pålidelig.
