Ako baka vidi gusku, sigurno će joj dati malo kruha, iako joj uvijek kažem da to ne radi.

Baka is the subject of the clause, so it stays in the nominative singular.

• baka = grandmother/grandma
• nominative is the basic dictionary form

You would use baku only when grandma is the direct object, for example: Vidim baku = I see grandma.

Because gusku is the direct object of vidi.

• guska = goose, nominative singular
• gusku = accusative singular

After a verb like vidjeti (to see), the thing seen usually goes in the accusative:

• baka vidi gusku = grandma sees a goose

For many feminine nouns ending in -a, the accusative singular ends in -u.

In Croatian, a real future condition is normally expressed with:

• ako + present
• main clause in the future

So:

• Ako baka vidi gusku, ... će dati ...

This is very similar to English:

• If grandma sees a goose, she will give it some bread.

English also usually says if she sees, not if she will see.

Here sigurno is an adverb, meaning surely, certainly, or sometimes very likely depending on context.

It is not agreeing with any noun, so it is not an adjective here.

Compare:

• sigurna baka = a sure/certain grandma — adjective
• baka će sigurno dati = grandma will surely give — adverb

So in this sentence, sigurno describes the whole action: she will surely/certainly give some bread.

Će helps form the future tense.

• dati = to give
• će dati = will give

Croatian future I is formed with a form of htjeti plus the infinitive:

• ja ću dati
• ti ćeš dati
• ona će dati

In this sentence:

• sigurno će joj dati

The word će is an enclitic, which means it normally appears near the beginning of its clause, often in the second position after the first stressed element.

That is why će comes after sigurno here.

They are the same form, but they refer to different people/things.

1. sigurno će joj dati malo kruha
   Here joj means to the goose.

2. iako joj uvijek kažem
   Here joj means to grandma.

In both cases, joj is the dative singular form meaning to her.

Croatian often leaves this kind of reference to context, so learners have to pay attention to who makes sense in each part of the sentence.

Because guska is a grammatically feminine noun.

Croatian pronouns follow grammatical gender, not necessarily natural sex or English-style it.

So:

• guska = feminine noun
• dative singular = joj

Literally it looks like to her, but in natural English translation you would usually say to it:

• dati joj malo kruha = give it some bread

After quantity words like malo (a little, some), Croatian usually puts the noun in the genitive.

So:

• kruh = bread, nominative
• kruha = bread, genitive

That gives:

• malo kruha = a little bread / some bread

This is very common with amounts and quantities:

• puno vode = a lot of water
• malo vremena = a little time
• komad kruha = a piece of bread

Iako means although or even though.

It introduces a concessive subordinate clause: a clause that presents a contrast.

So:

• iako joj uvijek kažem da to ne radi
• although I always tell her not to do that

It signals: this is true despite that other fact.

Because Croatian very often uses da + present tense after verbs like reći or kazati when reporting instructions, requests, or indirect commands.

So:

• kažem joj da to ne radi
• literally: I tell her that she not do that
• natural English: I tell her not to do that

This is a very normal Croatian pattern. English often prefers an infinitive, but Croatian often prefers a subordinate clause with da.

Raditi here means to do in a general or repeated sense.

The speaker says:

• uvijek kažem = I always tell her

That suggests a habitual/repeated situation, so da to ne radi means that she shouldn’t do that / keep doing that.

A perfective verb like uraditi would sound more like do it once, complete it, which is less natural here.

So ne radi fits the idea of a repeated behavior better.

To means that, and it refers to the whole action mentioned earlier:

• giving the goose some bread

So:

• kažem joj da to ne radi
• I tell her not to do that

Croatian often uses to to point back to an earlier idea or action, just like English that.

The commas separate the subordinate clauses from the main clause.

The sentence has this structure:

• Ako baka vidi gusku, = if grandma sees a goose
• sigurno će joj dati malo kruha,
• iako joj uvijek kažem da to ne radi. = although I always tell her not to do that

So the commas help show the clause boundaries:

1. after the if-clause
2. before the although-clause

This is standard Croatian punctuation.
