Hvis rækkefølgen af ordene er rigtig, giver sætningen mere mening.

Because Danish main clauses usually follow the V2 rule: the finite verb comes in the second position.

In this sentence, the whole Hvis rækkefølgen af ordene er rigtig clause comes first. That entire clause counts as position 1, so the verb giver must come next, in position 2.

So the structure is:

Hvis rækkefølgen af ordene er rigtig = first element
giver = second element, the finite verb
sætningen = subject after the verb

That is why Danish says:

Hvis rækkefølgen af ordene er rigtig, giver sætningen mere mening.

and not:

Hvis rækkefølgen af ordene er rigtig, sætningen giver mere mening.

For an English speaker, this is one of the most important Danish word-order patterns to learn.

Because the first part is a subordinate clause, and the second part is a main clause.

In the subordinate clause after hvis, Danish normally uses a more straightforward subject-verb order:

rækkefølgen ... er rigtig

But in the main clause, Danish uses the V2 rule, so when something else comes first, the verb comes before the subject:

giver sætningen mere mening

So the sentence shows two different systems at once:

• Subordinate clause: normal subject + verb order
• Main clause: verb in second position

That contrast is very typical in Danish.

Because rigtig agrees with rækkefølgen, which is a common-gender singular noun.

In Danish predicate adjectives often agree with the noun they describe:

• en rækkefølge → rigtig
• et ord → rigtigt
• flere ord → rigtige

So here:

rækkefølgen ... er rigtig

uses rigtig because rækkefølge is a common-gender noun.

If the subject were a neuter noun, you would expect rigtigt instead.

Yes. Rækkefølgen af ordene means the order of the words, and it is perfectly understandable Danish.

But there are other natural ways to say the same idea, for example:

• ordenes rækkefølge
• ordrækkefølgen

All three point to the same basic meaning.

For a learner:

• rækkefølgen af ordene is very transparent because it matches English the order of the words
• ordenes rækkefølge uses the Danish genitive
• ordrækkefølgen is a compound noun, which Danish uses very often

So the version in your sentence is fine, but not the only possibility.

Because Danish is referring to a specific word order and a specific sentence, not just any word order or any sentence.

• rækkefølgen = the order
• sætningen = the sentence

Danish often uses the definite form when the thing is already known from the context.

Also notice that Danish usually marks definiteness by adding an ending to the noun:

• rækkefølge → rækkefølgen
• sætning → sætningen

This is different from English, which usually adds a separate word, the.

Because mening here is part of the common expression give mening, which means to make sense.

So:

• Det giver mening = That makes sense
• Det giver mere mening = That makes more sense

In this expression, mening works like an uncountable idea noun, so you do not normally use en here.

To an English speaker, it may help to think of mere mening as matching more sense, not more an idea.

Give mening is a very common Danish expression meaning:

• make sense
• be logical
• be understandable

So giver sætningen mere mening means that the sentence becomes more understandable or more logical.

It is a fixed, everyday expression, and learners will hear it a lot.

Examples:

• Det giver ikke mening. = That doesn’t make sense.
• Nu giver det mening. = Now it makes sense.

Here, hvis means if.

It introduces a condition:

Hvis rækkefølgen af ordene er rigtig = If the order of the words is correct

In some contexts, hvis can also correspond to whether, but in this sentence it is clearly conditional, so if is the right interpretation.

For example:

• Jeg ved ikke, hvis ... would usually not be the normal modern way to say I don’t know whether ...
• In modern Danish, om is more commonly used for whether

So in your sentence, think only of hvis = if.

Yes. The comma separates the initial subordinate clause from the main clause:

Hvis rækkefølgen af ordene er rigtig, giver sætningen mere mening.

This kind of comma is normal in Danish when a subordinate clause comes before the main clause.

So the comma helps show the structure:

• first the condition
• then the result

Yes, korrekt would also work:

Hvis rækkefølgen af ordene er korrekt, giver sætningen mere mening.

The difference is mostly one of tone and nuance:

• rigtig is very common and everyday
• korrekt sounds a bit more formal or technical

In many contexts, both are possible. A learner should know that rigtig is extremely common in ordinary Danish.

Mere means more, so it implies a comparison.

The sentence suggests:

• when the word order is correct, the sentence makes more sense
• than it would if the word order were wrong
• or more sense than before

Danish often leaves that comparison implicit, just as English does.

So you do not need an extra phrase like than otherwise for the sentence to feel complete.
