Tijesto je još ljepljivo, pa ću dodati malo brašna.

Because tijesto is a neuter singular noun in Croatian, and adjectives must agree with the noun in gender, number, and case.

So:

• ljepljiv = masculine singular
• ljepljiva = feminine singular
• ljepljivo = neuter singular

Since tijesto is neuter, the correct form is ljepljivo.

You can compare:

• Kruh je tvrd. = The bread is hard. (masculine)
• Juha je dobra. = The soup is good. (feminine)
• Tijesto je ljepljivo. = The dough is sticky. (neuter)

Here još means still.

So Tijesto je još ljepljivo means The dough is still sticky.

Common meanings of još include:

• still → Još čekam. = I am still waiting.
• more / another → Hoćeš još kave? = Do you want more coffee?
• yet in some contexts

In this sentence, still is the natural meaning.

Pa often means so, and so, then, or well, depending on context.

In this sentence, it links the two ideas naturally:

• The dough is still sticky
• so I’ll add a little flour

So pa works like so here.

It is very common in everyday Croatian and often sounds more natural and conversational than a heavier connector like zato or stoga.

Rough comparison:

• ..., pa ću dodati malo brašna. = ..., so I’ll add a little flour.
• ..., zato ću dodati malo brašna. = ..., therefore I’ll add a little flour. (more explicit / sometimes slightly stronger)

In standard Croatian, ću is a clitic, and clitics usually go in the second position in the clause.

So the normal standard order is:

• pa ću dodati

not

• pa dodati ću

The future tense here is formed with:

• ću = auxiliary for I will
• dodati = infinitive

So ću dodati = I will add

You may sometimes see different word order in informal writing or older usage, but pa ću dodati is the standard form learners should use.

Dodati is the perfective infinitive, and it fits well here because the speaker is talking about a single complete action: adding some flour.

• dodati = to add (once, as a completed action)
• dodavati = to be adding / to add repeatedly or over time (imperfective)

Since the meaning is I’ll add a bit of flour now, Croatian normally uses the perfective verb:

• ću dodati

If you used dodavati, it would suggest a more ongoing or repeated process, which is less natural in this sentence.

Because after quantity words like malo meaning a little, Croatian normally uses the genitive.

So:

• malo brašna = a little flour

Here:

• brašno is the basic form (nominative)
• brašna is the genitive singular

This is very common with amounts and quantities, especially with mass nouns:

• puno vode = a lot of water
• malo šećera = a little sugar
• dosta vremena = enough time

So malo brašna is exactly what you would expect grammatically.

Here malo functions as a quantifier meaning a little or a small amount of.

It is not an adverb in this sentence.

Compare:

• Dodao sam malo brašna. = I added a little flour.
  → malo = quantity word

• Malo sam umoran. = I’m a little tired.
  → malo = adverb-like, modifying the adjective

So in your sentence, malo introduces an amount, and that is why the following noun is in the genitive: brašna.

Yes, ljepljiv / ljepljiva / ljepljivo is the normal adjective for sticky.

So:

• Tijesto je ljepljivo. = The dough is sticky.

You may also hear similar wording depending on context, but ljepljivo is the straightforward, standard choice here.

A useful thing to notice is that Croatian often uses adjectives like this after biti:

• Kava je vruća. = The coffee is hot.
• Juha je slana. = The soup is salty.
• Tijesto je ljepljivo. = The dough is sticky.

Yes. Još uvijek also means still, and it is perfectly natural here.

So both are possible:

• Tijesto je još ljepljivo.
• Tijesto je još uvijek ljepljivo.

The version with još uvijek is slightly more explicit, while još alone is shorter and very common.

In everyday speech, još often sounds completely natural and sufficient.

In Croatian, the verb biti (to be) is normally required in this kind of sentence.

So:

• Tijesto je ljepljivo. = The dough is sticky.

Here je is the 3rd person singular present of biti.

Dropping it would be ungrammatical in standard Croatian:

• Tijesto ljepljivo ❌

Croatian does allow omission of subject pronouns quite often, but not of this copula in a normal sentence like this.

Yes, Croatian word order is fairly flexible, but not every version sounds equally natural.

The original sentence:

• Tijesto je još ljepljivo, pa ću dodati malo brašna.

is very natural.

Possible variations include:

• Još je tijesto ljepljivo, pa ću dodati malo brašna.
• Pa ću dodati malo brašna jer je tijesto još ljepljivo.

But the original order is probably the best neutral version for a learner to remember.

One important point: although word order can move around, clitics like je and ću still follow special placement rules, so you should not move words freely without checking those rules.

A rough pronunciation guide is:

• Tijesto ≈ TYE-stoh
• je ≈ yeh
• još ≈ yosh
• ljepljivo ≈ LYEP-lyee-voh
• pa ≈ pah
• ću ≈ roughly chyoo
• dodati ≈ doh-DAH-tee
• malo ≈ MAH-loh
• brašna ≈ BRAHSH-nah

A few sounds that may feel unusual for English speakers:

• j is pronounced like English y
• lj is a single palatal sound, somewhat like the lli in some pronunciations of million
• š sounds like sh
• ć is a soft ch-like sound

So the sentence flows roughly like:

TYE-stoh yeh yosh LYEP-lyee-voh, pah chyoo doh-DAH-tee MAH-loh BRAHSH-nah.
