Vikendom najviše volim šetati uz rijeku.

Because Croatian often uses a singular case form as a time expression. Here, vikendom is the instrumental singular of vikend.

So even though the form is singular, the meaning is often general and repeated: on weekends rather than on one weekend.

Here, najviše means most.

So najviše volim šetati means I like walking the most or walking is what I like most.

It comes from the comparison pattern:

• mnogo / puno = much, a lot
• više = more
• najviše = most

It can mean either, depending on context.

In this sentence, volim šetati normally means I like walking or I enjoy walking, not a very strong emotional love. With activities, voljeti often corresponds to English like or enjoy.

Because Croatian commonly uses voljeti + infinitive to say that someone likes doing something.

For example:

• Volim čitati. = I like reading.
• Volim kuhati. = I like cooking.
• Volim šetati. = I like walking.

English can use either I like to walk or I like walking. Croatian uses the infinitive here.

Šetati usually means to stroll, to take a walk, or to walk for pleasure.

Hodati is more general: to walk, to go on foot, or simply to be able to walk.

So in this sentence, šetati is a better choice because it suggests a pleasant leisure activity by the river, not just the physical act of walking.

Yes, šetati is an imperfective verb.

That fits well here because the sentence describes a habitual, repeated activity: something the speaker likes doing on weekends in general.

A perfective verb such as prošetati would suggest taking a walk once or for a certain occasion, which is less natural in this kind of general preference statement.

The preposition uz usually means along, by, or next to, especially with movement along something.

It takes the accusative case.

The noun is:

• rijeka = river
• rijeku = accusative singular

So uz rijeku means along the river or by the river.

Because Croatian does not have articles like English a and the.

That means rijeku can be understood from context as a river or the river. In this sentence, English naturally uses the river, but Croatian does not need a separate word for that.

Yes. Croatian word order is fairly flexible.

The original sentence, Vikendom najviše volim šetati uz rijeku, is very natural and puts vikendom first to set the time frame.

If you change the order, the basic meaning can stay the same, but the emphasis may shift. Croatian often moves words around for focus, rhythm, or style more freely than English does.
