Preporuka još vrijedi.

Preporuka is a noun, and here it is in the nominative singular because it is the subject of the sentence.

• preporuka = recommendation
• gender: feminine
• number: singular

So in Preporuka još vrijedi., preporuka is the thing that still applies / is still valid.

Here još means still.

So it adds the idea that the recommendation was valid before, and it continues to be valid now.

Common meanings of još include:

• still → Još čekam. = I am still waiting.
• more / another → Još kave, molim. = More coffee, please.
• sometimes yet, depending on context

In this sentence, still is the natural meaning.

Vrijedi is the 3rd person singular present tense of the verb vrijediti.

In Croatian, vrijediti can mean several related things, depending on context:

• to be valid / to apply
• to be worth
• to count

In Preporuka još vrijedi., it means is still valid / still applies.

For example:

• Ova karta još vrijedi. = This ticket is still valid.
• To pravilo više ne vrijedi. = That rule no longer applies.
• Koliko to vrijedi? = How much is that worth?

Because the subject preporuka is:

• singular
• third person
• grammatical gender does not change the present-tense verb form here

So the verb must be vrijedi, the 3rd person singular present form.

A quick pattern:

• ja vrijedim = I am worth / I count
• ti vrijediš = you are worth / you count
• on/ona/ono vrijedi = he/she/it is valid / counts
• mi vrijedimo
• vi vrijedite
• oni/one/ona vrijede

Since preporuka is one thing, you use vrijedi.

Croatian has no articles, so there is no direct equivalent of the or a/an.

That means preporuka can mean:

• a recommendation
• the recommendation

The exact meaning depends on context.

In real use, the listener usually already knows which recommendation is meant, or the situation makes it clear.

Yes. Croatian word order is more flexible than English word order, although some versions sound more natural than others depending on emphasis.

The most neutral order here is:

• Preporuka još vrijedi.

Other possible orders include:

• Još vrijedi preporuka.
• Preporuka vrijedi još. — possible, but less natural in many contexts

Why change the order?

• to emphasize još
• to fit the rhythm of the sentence
• to connect better with previous information

Even though word order can change, the standard neutral version for a learner is best kept as Preporuka još vrijedi.

A rough pronunciation guide is:

• preporuka ≈ preh-poh-ROO-kah
• još ≈ yosh
• vrijedi ≈ VRYEH-dee

A few useful points:

• j in Croatian is pronounced like English y
• š sounds like English sh
• ije in vrijedi can be tricky for English speakers; say it smoothly, not as three strongly separated syllables

A more careful breakdown:

• pre-po-ru-ka
• još
• vri-je-di

No, but it is a very natural and common choice.

Depending on context, Croatian speakers might also use other verbs, such as:

• važiti = to be valid, to apply
• ostati na snazi = to remain in force
• biti važeći = to be valid

For example:

• Preporuka još važi.
• Preporuka je još važeća.

However, there is a nuance:

• vrijedi often sounds broad and natural for rules, tickets, offers, statements, or recommendations that still apply
• važi / važi is also common, especially in some regional standards and everyday speech

So Preporuka još vrijedi. is correct and idiomatic.

Yes, speakers of closely related languages would understand it very easily.

In Croatian, vrijedi is standard. In other varieties in the region, you may also see or hear:

• Preporuka još vredi.
• Preporuka još važi.

The differences are mostly in standard usage and regional preference, not in core meaning.

If you are learning Croatian specifically, vrijedi is a good form to learn.

Yes. Preporuka has a wider range than just one English word.

Depending on context, it can mean:

• recommendation
• referral
• endorsement
• letter of recommendation / reference

So Preporuka još vrijedi. could mean something like:

• the recommendation still stands
• the recommendation is still valid
• the referral is still valid

The exact English translation depends on the situation.

You negate it by putting ne before the verb:

• Preporuka više ne vrijedi.

This usually means:

• The recommendation is no longer valid.
• The recommendation no longer applies.

Notice that with negation, Croatian often uses više ne for no longer:

• još vrijedi = still applies
• više ne vrijedi = no longer applies

That pair is very useful to learn.
