Taj dječak svaki dan vozi romobil do škole.

Taj means that. It is a demonstrative adjective and it agrees with dječak in gender, number, and case.

• taj = masculine singular nominative
• dječak = masculine singular nominative

So taj dječak = that boy.

In context, Croatian often uses taj where English might simply say the or might not stress that very strongly.

Dječak is in the nominative singular because it is the subject of the sentence — the one doing the action.

The sentence is about that boy, and he is the one who rides the scooter, so the noun stays in the subject form:

• taj dječak = that boy as the subject

Croatian often omits subject pronouns like on (he) because the verb form already shows the person and number.

Here, the subject is already clearly stated as taj dječak, so adding on would usually be unnecessary.

• Taj dječak svaki dan vozi romobil do škole. = natural
• Taj dječak on svaki dan vozi... = normally redundant unless you are emphasizing he

Svaki dan literally means every day.

This is a common time expression. In this sentence, it functions adverbially: it tells you when/how often the action happens.

Formally, it is often explained as an accusative expression of time. Because dan is a masculine inanimate noun, its accusative singular looks the same as the nominative:

• nominative: dan
• accusative: dan

That is why you see:

• svaki dan = every day

You may also hear svakog dana, which also means every day. Both are common.

Vozi is the 3rd person singular present tense form of voziti.

It matches the subject taj dječak because the subject is:

• third person = he
• singular = one boy

So:

• ja vozim = I ride/drive
• ti voziš = you ride/drive
• on/ona/ono vozi = he/she/it rides/drives

Here, vozi means he rides/drives.

Voziti can mean to drive or to ride, depending on the object and context.

With romobil, the most natural English translation is usually ride a scooter.

So:

• vozi romobil = rides a scooter

Also, voziti is imperfective, which makes sense here because svaki dan shows a habitual, repeated action.

Romobil is the direct object of the verb — it is the thing being ridden — so it is in the accusative case.

However, romobil is a masculine inanimate noun, and for masculine inanimate nouns, the accusative singular is the same as the nominative singular.

So:

• nominative: romobil
• accusative: romobil

That is why the form does not change.

Do škole means to school or more literally up to the school.

The preposition do is often used with movement toward a destination. It focuses on the endpoint.

So:

• do škole = to school / as far as the school

This is very natural in Croatian.

Because the preposition do always takes the genitive case.

The noun is škola in the dictionary form, but after do it becomes škole:

• nominative: škola
• genitive: škole

So:

• do škole = to school

Yes, u školu is also possible in many contexts, but it is not exactly the same in nuance.

• do škole = to the school, up to the school, focusing on the destination
• u školu = into school / to school, often with the idea of entering or going there as a place/institution

In everyday speech, both can be used in similar situations, but do škole fits very naturally with travel or transport to the school.

Yes. Croatian word order is more flexible than English because case endings show the grammatical roles.

The sentence given is a neutral, natural order:

• Taj dječak svaki dan vozi romobil do škole.

But other orders are possible, for example:

• Taj dječak vozi romobil do škole svaki dan.
• Svaki dan taj dječak vozi romobil do škole.

These versions are still grammatical, but the focus or emphasis changes slightly.

A rough pronunciation guide is:

• dječak ≈ dye-chaak

A few useful points:

• dj sounds somewhat like the start of duke in some English accents, or a soft dy
• č sounds like ch in church
• Croatian spelling is quite regular, so words are usually pronounced close to how they are written

So dječak is approximately dye-chak, with the č clearly pronounced as ch.
