Lidt ros gør hende mere rolig, og hun tager kritik roligt for at blive bedre.

Lidt ros means a little praise or some praise.

A few useful points:

• ros is usually an uncountable noun, like praise in English.
• Because of that, you normally do not use en/et with it.
• lidt is a very common way to mean a little or some with uncountable nouns.

So:

• lidt ros = a little praise / some praise
• noget ros can also be possible in some contexts, but lidt ros sounds very natural here

You would not say en ros here, because that would treat ros like a countable thing.

Because hende is the object form of hun.

After the verb gør in this sentence, the person being affected is the object:

• hun = she
• hende = her

So:

• Lidt ros gør hende mere rolig = A little praise makes her calmer

Compare:

• Hun tager kritik roligt = She takes criticism calmly
• Det gør hende rolig = It makes her calm

English also does this:

• She takes it
• It affects her

Here gør means makes in the sense of causes someone to become something.

So:

• gør hende mere rolig = makes her calmer

This is a very common Danish pattern:

• noget gør nogen glad = something makes someone happy
• noget gør nogen træt = something makes someone tired
• noget gør nogen mere sikker = something makes someone more confident

So in this sentence, gør is not do in the ordinary sense. It is make/makes.

Because rolig here is an adjective describing her, not an adverb.

In gør hende mere rolig:

• mere = more
• rolig = calm

Together they mean calmer or literally more calm.

Why not roligt?

• roligt is usually the adverb form, meaning calmly
• Here we are describing her state, so we need the adjective rolig

Why not rolige?

• rolige is often used in plural or definite forms
• Here it is singular and predicative, so rolig is correct

So the contrast is:

• hun er rolig = she is calm
• hun tager det roligt = she takes it calmly / she takes it easy

Because they do two different jobs.

• rolig is an adjective
• roligt is an adverb

In the sentence:

• mere rolig describes hende → her condition/state
• tager kritik roligt describes how she takes criticism → the manner of the action

So:

• hun bliver rolig = she becomes calm
• hun reagerer roligt = she reacts calmly

This adjective/adverb distinction is very common in Danish. Often the adverb is formed with -t:

• rolig → roligt
• hurtig → hurtigt
• langsom → langsomt

Literally, tager kritik roligt means takes criticism calmly.

Yes, this is a very natural Danish expression.

The pattern tage noget roligt is common and means to deal with something in a calm way:

• tage det roligt = take it easy / stay calm
• tage nyheden roligt = take the news calmly
• tage kritik roligt = take criticism calmly

So the sentence means she does not get overly upset or defensive when criticized.

Because kritik is usually used as an uncountable noun, much like criticism in English.

So:

• hun tager kritik roligt = she takes criticism calmly

This is similar to English, where you often say:

• She accepts criticism well
• not necessarily She accepts the criticism well

If you wanted to refer to specific criticism, you could use an article or determiner in Danish:

• hun tager kritikken roligt = she takes the criticism calmly
• hun tager min kritik roligt = she takes my criticism calmly

But in your sentence, kritik means criticism in a general sense.

for at blive bedre expresses purpose. It means in order to improve or to get better.

Breakdown:

• for at = in order to / to
• blive = become
• bedre = better

So:

• hun tager kritik roligt for at blive bedre = she takes criticism calmly in order to improve

This structure is very common in Danish:

• Jeg læser dansk for at blive bedre = I study Danish to get better
• Hun træner for at blive stærkere = She trains to become stronger

It can mean both, depending on how natural you want the English to sound.

Literally:

• blive = become
• bedre = better

So the literal sense is become better.

But in natural English, we often say get better or improve. So all of these can fit:

• to become better
• to get better
• to improve

In this sentence, to improve is probably the most natural overall translation.

Because og simply joins two main clauses, and the normal word order stays the same.

The two clauses are:

• Lidt ros gør hende mere rolig
• hun tager kritik roligt for at blive bedre

When joined with og, Danish keeps standard main-clause order:

• subject + verb
• og hun tager ...

You would usually get inversion only when something else is placed first in the clause, for example:

• Derfor tager hun kritik roligt = Therefore, she takes criticism calmly

Here derfor comes first, so the verb comes before the subject. But after og, that does not happen automatically.

Yes. rolig can mean calm, quiet, or peaceful, depending on context.

That can be confusing for English speakers. In this sentence, the sense is clearly calm:

• mere rolig = calmer
• roligt = calmly

But in other contexts:

• Det er roligt her = It is quiet here
• en rolig person = a calm person
• en rolig aften = a quiet/peaceful evening

So the exact English word depends on context, but the core idea is lack of agitation, noise, or stress.
