Når man viser hensyn og er opmærksom på andre, er det lettere at skabe tillid.

Når means when here. It introduces a time/condition clause:

• Når man viser hensyn og er opmærksom på andre = When you/people show consideration and are attentive to others

In Danish, når is often used for things that are generally true or happen repeatedly. In a sentence like this, it has a broad meaning close to whenever or when one....

Compare:

• Når det regner, bliver vejene glatte. = When it rains, the roads get slippery.
• Når man er træt, laver man flere fejl. = When you’re tired, you make more mistakes.

So it is not necessarily about one specific moment, but a general pattern.

No. In Danish, man is an impersonal pronoun meaning one, you (in a general sense), or people.

So:

• Når man viser hensyn... = When one shows consideration...
• More natural English: When you show consideration...
• Or: When people show consideration...

This is a very common word in Danish.

Examples:

• Man siger, at... = People say that...
• Hvordan gør man det? = How do you do that?
• I Danmark cykler man meget. = In Denmark, people cycle a lot.

So man here is general, not specifically male.

Literally, viser hensyn means shows consideration.

It is a fixed expression:

• at vise hensyn = to show consideration / to be considerate

Here:

• viser = shows
• hensyn = consideration

Danish often uses a verb + noun expression where English might also use an adjective or a different structure.

Examples:

• Du skal vise hensyn til andre. = You should show consideration for others.
• Hun viser stor hensyn. would actually sound wrong; normally you would say Hun viser stort hensyn because hensyn is a neuter noun.

A very common full expression is:

• at vise hensyn til nogen = to show consideration for someone

In your sentence, the til andre part is not repeated because the next phrase already mentions andre:

• viser hensyn og er opmærksom på andre

Because viser and er are two coordinated verbs sharing the same subject man.

So this part is structured like:

• man viser hensyn og er opmærksom på andre

That means:

• man = subject
• viser = first verb
• og = and
• er = second verb

English works similarly:

• When you show consideration and are attentive to others...

You do not need at here because at is the infinitive marker, like to in English. But viser and er are finite verbs, not infinitives.

opmærksom på means aware of, attentive to, or mindful of, depending on context.

It is a common adjective + preposition combination:

• opmærksom på noget/nogen = aware of / attentive to something/someone

Examples:

• Jeg er opmærksom på problemet. = I am aware of the problem.
• Hun er meget opmærksom på børnene. = She is very attentive to the children.

The preposition på is simply the one Danish uses with opmærksom. This is something learners usually just have to memorize, much like English combinations such as interested in or good at.

andre here means others in a general sense.

So:

• opmærksom på andre = attentive to others

If you said de andre, that would mean the others, referring to a specific group already known from context.

Compare:

• Tænk på andre. = Think of others.
• Tænk på de andre. = Think of the others / the other people

In your sentence, the meaning is general, so andre is the natural choice.

This is because the sentence begins with a subordinate clause introduced by Når. After that clause, the main clause follows, and Danish main clauses obey the V2 rule: the finite verb comes in second position.

Structure:

• Når man viser hensyn og er opmærksom på andre = subordinate clause
• er det lettere at skabe tillid = main clause

In the main clause, er comes before det because the whole Når... clause takes first position.

So:

• Når ..., er det lettere...

If the main clause came first, you would get:

• Det er lettere at skabe tillid, når man viser hensyn og er opmærksom på andre.

Both are correct.

Because the sentence starts with another element first: the Når... clause.

Danish main clauses usually put the finite verb in second position. Since the subordinate clause is occupying the first position, the verb er must come next:

• Når man viser hensyn..., er det lettere...

If the sentence started directly with det, then you would say:

• Det er lettere at skabe tillid.

This is a very important Danish word-order pattern.

Compare:

• I dag er det koldt. = Today it is cold.
• Når jeg arbejder, er jeg fokuseret. = When I work, I am focused.

Here det is a formal/dummy subject, similar to English it in sentences like:

• It is easier to create trust.

So:

• er det lettere at skabe tillid = it is easier to create trust

The det does not refer to a concrete object. It is just required by the sentence structure.

This is very common in Danish:

• Det er vigtigt at lytte. = It is important to listen.
• Det er svært at forstå. = It is difficult to understand.

Because lettere is the comparative form of let:

• let = easy
• lettere = easier
• lettest = easiest

So:

• Det er let. = It is easy.
• Det er lettere. = It is easier.
• Det er lettest sådan. = It is easiest that way.

In your sentence, the idea is comparative: when you act considerately and pay attention to others, creating trust becomes easier.

at skabe tillid is an infinitive phrase meaning to create trust or to build trust.

Breakdown:

• at = infinitive marker, like to
• skabe = create
• tillid = trust

So the main clause is:

• er det lettere at skabe tillid = it is easier to create trust

This pattern is very common:

• Det er godt at lære dansk. = It is good to learn Danish.
• Det er svært at finde tid. = It is hard to find time.

Yes, absolutely. at skabe tillid literally means to create trust, but in natural English to build trust is often the best translation.

So depending on style, you could understand it as:

• to create trust
• to build trust
• sometimes even to establish trust

All are possible, but build trust often sounds the most natural in English.

In this sentence, tillid is used as an uncountable noun meaning trust in a general sense.

So:

• at skabe tillid = to create/build trust

No article is needed, just like in English when speaking generally:

• Trust is important.
• Det er vigtigt med tillid.

If Danish wants to specify a particular trust relationship, the wording may change depending on context, but here it is general and abstract, so no article is used.

Yes. The original sentence is natural, but slightly formal or polished. A few similar Danish versions are:

• Når man tager hensyn og tænker på andre, er det lettere at skabe tillid.
• Det er lettere at skabe tillid, når man viser hensyn og er opmærksom på andre.

Notes:

• tage hensyn is another very common expression meaning show consideration / take others into account
• tænke på andre = think of others

So the original sentence is correct and natural, but there are several close alternatives depending on style.
