Ne volim gurati kolica kroz veliku gužvu u supermarketu.

Croatian often drops subject pronouns when they are obvious from the verb.

• volim already means I like / I love
• so Ne volim... naturally means I don't like...

You could say Ja ne volim..., but that usually adds emphasis, like I don’t like it.

This is a very common Croatian pattern:

• voljeti = to like / to love
• volim = I like
• ne volim = I don't like
• gurati = to push

So Ne volim gurati... literally works like I don't like to push... or I don't like pushing...

Croatian often uses voljeti + infinitive in this way.

This is about aspect, which is very important in Croatian verbs.

• gurati = imperfective → ongoing, repeated, general activity
• gurnuti = perfective → a single completed push

In this sentence, the speaker is talking about a general dislike of the activity, not one single push, so gurati is the natural choice.

So:

• Ne volim gurati kolica... = I don't like pushing carts...
• Ne volim gurnuti... would sound wrong here because it suggests a one-time completed action.

Because kolica is one of those Croatian nouns that are plural in form even when they refer to one object.

This is called a plural-only noun (often called pluralia tantum).

So:

• kolica = shopping cart / stroller / little cart, but grammatically plural

That means it behaves like a plural noun in agreement and case forms, even when English would use singular cart.

Here kolica is in the accusative plural, because it is the direct object of gurati.

However, for this noun, the accusative plural looks the same as the nominative plural:

• kolica = nominative plural
• kolica = accusative plural

So even though the form does not change, its function in the sentence is object.

Because the preposition kroz always takes the accusative case and usually means through.

Here:

• gužva = crowd, congestion, crush
• accusative singular = gužvu
• velika becomes veliku to match the accusative singular feminine noun

So:

• kroz veliku gužvu = through a big crowd

This is a good chunk to remember:

• kroz + accusative

Gužva can mean:

• a crowd
• congestion
• a packed, busy situation
• sometimes even rush / hustle / crush

In this sentence, it suggests a place full of people where it is hard to move around, so crowd or heavy crowding fits well.

Because u can take different cases depending on meaning:

• u + locative = in / inside a place, when talking about location
• u + accusative = into a place, when talking about movement toward it

Here the meaning is location:

• u supermarketu = in the supermarket

Compare:

• Ja sam u supermarketu. = I am in the supermarket.
• Idem u supermarket. = I am going into/to the supermarket.

No, Croatian word order is fairly flexible, but this version sounds neutral and natural.

This order presents the information clearly:

• Ne volim = I don't like
• gurati kolica = pushing the cart
• kroz veliku gužvu = through a big crowd
• u supermarketu = in the supermarket

You could move things around for emphasis, for example:

• U supermarketu ne volim gurati kolica kroz veliku gužvu.
• Kolica ne volim gurati kroz veliku gužvu u supermarketu.

These are possible, but the original is the most straightforward.

Yes.

• trgovina = shop/store
• supermarket = supermarket

So:

• u trgovini = in the store
• u supermarketu = in the supermarket

U supermarketu is more specific.
U trgovini is more general.

Croatian usually does not mark definiteness the way English does with a/the.

So veliku gužvu can mean:

• a big crowd
• the big crowd

The exact meaning depends on context.

In many ordinary translations, English would use a big crowd unless the crowd has already been mentioned.

Both are possible, but the second often sounds more natural in everyday English:

• I don't like pushing a cart through big crowds in the supermarket.

That is because Croatian Ne volim gurati kolica... expresses a general dislike, and English often uses -ing for that kind of statement.

Still, I don't like to push a cart... is also grammatically fine.

A rough pronunciation guide:

• Ne volim ≈ neh VO-leem
• gurati ≈ goo-RAH-tee
• kolica ≈ KO-lee-tsa
• kroz ≈ krohz
• veliku ≈ VEH-lee-koo
• gužvu ≈ GOOZH-voo
• u supermarketu ≈ oo soo-pehr-MAR-keh-too

A few sounds to notice:

• ž sounds like the s in measure
• c sounds like ts
• Croatian stress is not always marked in normal writing, so listening to native audio is very helpful.

Yes. Kolica can refer to different kinds of wheeled small carts depending on context, for example:

• a shopping cart
• a stroller / pram / buggy
• a small cart

In this sentence, because of u supermarketu, the meaning is clearly shopping cart.
