En el informe quiero destacar solo los puntos más importantes.

En el informe means in the report or in the context of the report.

It comes first because Spanish often moves a phrase to the front to set the scene or topic. Here, it tells you right away where the action applies.

So:

• En el informe quiero destacar... = In the report, I want to highlight...
• Quiero destacar... en el informe is also possible, but it sounds a little less natural here and can slightly change the focus.

Also, en is used because the speaker is talking about something within the report, not something from it.
For example:

• en el informe = in the report
• del informe = from the report / of the report

Spanish usually needs an article where English sometimes does not.

So el informe means the report. It suggests a specific report that both speaker and listener understand from the context.

In Spanish, leaving out the article here would sound incomplete or unnatural:

• En el informe... = correct
• En informe... = not correct

In Spanish, subject pronouns are often omitted because the verb ending already shows who the subject is.

Here, quiero clearly means I want, so yo is not necessary.

• quiero = I want
• yo quiero = I want

Using yo is possible, but it usually adds emphasis, contrast, or clarity:

• Yo quiero destacar... = I want to highlight...
  (maybe contrasting with what someone else wants)

So the sentence without yo is the normal, natural choice.

After querer when you mean to want to do something, Spanish uses an infinitive.

So:

• quiero destacar = I want to highlight

This works like English:

• I want to highlight
• not I want I highlight

The pattern is:

• querer + infinitive

Examples:

• Quiero leer. = I want to read.
• Quiero explicar esto. = I want to explain this.
• Quiero destacar solo los puntos más importantes. = I want to highlight only the most important points.

Here destacar means something like:

• to highlight
• to emphasize
• to bring out
• to draw attention to

In the context of a report, destacar is a very natural verb for pointing out the key ideas.

Depending on context, similar verbs could be:

• resaltar = to highlight, to make stand out
• subrayar = to underline, emphasize

But destacar is a very common and neutral choice.

Here solo means only, and it limits los puntos más importantes.

So the idea is:

• I want to highlight only the most important points

The position is very natural:

• quiero destacar solo los puntos más importantes

This means the thing being limited is the points.

Compare:

• Solo quiero destacar los puntos más importantes
  = I only want to highlight the most important points
  This can suggest that highlighting is the only thing I want to do.

• Quiero destacar solo los puntos más importantes
  = I want to highlight only the most important points.
  This focuses more clearly on which points are being highlighted.

So word order affects what solo sounds like it is modifying.

Modern standard Spanish usually writes solo without an accent when it means only.

Traditionally, some people wrote:

• solo = alone
• sólo = only

But current standard spelling generally prefers solo in both cases, unless a writer wants to use the accent to avoid real ambiguity.

So in this sentence, solo without an accent is completely normal and correct.

Los puntos means the points. Spanish often uses the definite article where English might sometimes sound fine without it.

Here, the speaker is referring to a specific set of points in the report, not points in general.

So:

• los puntos más importantes = the most important points

If you said just puntos, it would sound less complete and less natural in this sentence.

There are two things happening here:

1. The adjective usually comes after the noun in Spanish.
So:

• puntos importantes = important points

That is the normal order.

2. The adjective must agree with the noun.
Puntos is masculine plural, so the adjective must also be plural:

• importante = singular
• importantes = plural

That is why we get:

• los puntos más importantes

Here it means the most important points.

The structure is:

• los + noun + más + adjective

This is a very common way to form a relative superlative in Spanish:

• el libro más interesante = the most interesting book
• los puntos más importantes = the most important points

So even though más by itself can mean more, the full structure here clearly means the most.

Yes. Solo and solamente can both mean only.

So you could say:

• En el informe quiero destacar solamente los puntos más importantes.

This is grammatically correct and natural.

The difference is mainly style:

• solo = shorter, very common
• solamente = a bit more explicit or slightly more formal in tone

Both are fine.

Yes, but changing the order can change the emphasis.

The original sentence:

• En el informe quiero destacar solo los puntos más importantes.

This sounds natural and puts in the report first as the frame.

Other possible versions:

• Quiero destacar solo los puntos más importantes en el informe.
  This is possible, but the final en el informe may sound like it modifies puntos or comes as an afterthought.

• Solo quiero destacar los puntos más importantes en el informe.
  This can mean I only want to highlight the most important points in the report, with more focus on only want.

So yes, word order is flexible in Spanish, but the original version is a very good, clear choice for this meaning.
