Uzmi još jedan gutljaj čaja, ali nemoj predugo žvakati taj tvrdi kruh.

Uzmi is the imperative singular of uzeti = to take.

So Uzmi još jedan gutljaj čaja means Take another sip of tea when speaking to one person in an informal way.

Related forms:

• uzeti = to take
• uzmi = take! (to one person)
• uzmite = take! (to more than one person, or politely to one person)

Croatian often uses the imperative very directly in everyday speech, just like English.

Yes, literally još often means still, yet, or more, but in this phrase još jedan is a very common expression meaning:

• another
• one more

So:

• još jedan gutljaj = another sip / one more sip

You will see this pattern a lot:

• još jedan dan = one more day / another day
• još jedna kava = another coffee
• još jedno pitanje = one more question

Because čaja is in the genitive case.

After many nouns that express a quantity, portion, or measure, Croatian uses the genitive:

• čaša vode = a glass of water
• komad kruha = a piece of bread
• gutljaj čaja = a sip of tea

So gutljaj is the main noun, and čaja tells you a sip of what.

Here:

• čaj = tea
• čaja = of tea

Because čaj is a masculine noun, and after a measure/portion noun like gutljaj, it normally appears in the genitive singular.

Declension here:

• nominative: čaj
• genitive: čaja

So:

• gutljaj čaja = sip of tea

This is a very important and common Croatian pattern.

Because Croatian usually forms the negative imperative with:

• nemoj + infinitive for one person
• nemojte + infinitive for plural/polite

So:

• nemoj žvakati = don’t chew
• nemojte žvakati = don’t chew (plural/polite)

You may sometimes encounter forms like ne žvači, but nemoj + infinitive is the standard, very common way learners should know first.

After nemoj, Croatian uses the infinitive.

So:

• nemoj + infinitive
• nemoj žvakati
• nemoj čekati
• nemoj govoriti

This is different from English, where we say don’t chew, with a bare verb form. In Croatian, nemoj carries the imperative force, and the second verb stays in the infinitive.

Predugo means too long or for too long.

It is an adverb:

• dugo = long / for a long time
• predugo = too long / excessively long

Examples:

• Spavao je dugo. = He slept a long time.
• Spavao je predugo. = He slept too long.

In your sentence:

• nemoj predugo žvakati = don’t chew for too long

Because pre- is a prefix here, attached directly to dugo.

This prefix often gives the sense of too, over-, or excessively:

• previše = too much
• prebrzo = too fast
• predugo = too long
• prekasno = too late

So predugo is a single adverb, not two separate words.

It is accusative singular, because the bread is the direct object of žvakati.

However, with masculine inanimate nouns, the accusative singular looks the same as the nominative singular.

So:

• nominative: taj tvrdi kruh
• accusative: taj tvrdi kruh

That is why nothing changes in form here.

The adjective and demonstrative both agree with kruh:

• taj = that
• tvrdi = hard
• kruh = bread

All three are masculine singular.

Because kruh is masculine inanimate, and in the accusative singular masculine inanimate nouns usually stay the same as the nominative.

Compare:

• Vidim kruh. = I see bread.
• Jedem kruh. = I’m eating bread.

But masculine animate nouns usually do change:

• Vidim psa. = I see the dog.
• nominative: pas
• accusative: psa

So kruh stays kruh, not kruha, because it is inanimate.

Here tvrdi is the masculine singular form of the adjective tvrd = hard.

Croatian adjective endings can look surprising at first. For masculine singular, many adjectives end in -i in the definite form:

• dobri čovjek
• veliki grad
• tvrdi kruh

So in taj tvrdi kruh, both taj and tvrdi describe kruh and agree with it in gender, number, and case.

Kruh is the standard Croatian word for bread.

Learners may also hear:

• hljeb
• hleb

Those are used in other South Slavic standards and regional varieties, but in standard Croatian, kruh is the expected form.

So for Croatian, kruh is the word you should learn and use.

Because ali means but, and it introduces a new clause.

The sentence has two imperative parts:

• Uzmi još jedan gutljaj čaja
• ali nemoj predugo žvakati taj tvrdi kruh

Croatian normally puts a comma before ali, just as English usually does before but when connecting two full clauses.

It is addressed to one person informally.

You can tell from:

• uzmi = singular informal imperative
• nemoj = singular informal negative imperative

If you were speaking to:

• more than one person, or
• one person politely

you would say:

• Uzmite još jedan gutljaj čaja, ali nemojte predugo žvakati taj tvrdi kruh.

Yes, aspect matters.

• uzeti is perfective: it refers to a completed act, so uzmi means take a sip as one whole action.
• žvakati is imperfective: it focuses on the ongoing action, so nemoj predugo žvakati means don’t keep chewing for too long.

This is very natural in Croatian:

• a single complete action: often perfective
• an ongoing activity, especially with duration like predugo: often imperfective

So the aspect choice fits the meaning very well.

Yes, Croatian word order is fairly flexible, but the given version sounds natural and neutral.

For example, you might also hear:

• Uzmi još jedan gutljaj čaja, ali taj tvrdi kruh nemoj predugo žvakati.

That version puts more emphasis on taj tvrdi kruh.

Still, the original sentence is probably the best basic model for a learner:

• Uzmi još jedan gutljaj čaja, ali nemoj predugo žvakati taj tvrdi kruh.

These sounds are often tricky for English speakers.

• ž is like the s in measure or vision

  • so žvakati begins with that sound

• lj is a single Croatian sound, not just l + j

  • it is somewhat similar to the lli sound in million for many English speakers
  • gutljaj contains this sound

Very rough pronunciation help:

• žvakati ≈ zhva-ka-ti
• gutljaj ≈ goot-lyai (very approximate)

The exact sound depends on accent, but that approximation is a useful start.
