Jež je polako prešao stazu i otišao u travu.

This is the Croatian past tense most learners first meet, often called the perfect.

It is formed with:

• the auxiliary je = is/has here functioning as a past-tense helper
• a past participle such as prešao or otišao

So:

• je prešao = crossed / has crossed
• (je) otišao = went away / has gone

In natural English, you would usually translate this with the simple past: crossed and went.

Because both verbs share:

• the same subject: jež
• the same tense
• the same auxiliary

So Croatian often uses the auxiliary only once:

• Jež je polako prešao stazu i otišao u travu.

This is completely normal. The second je is understood. A fuller version would be:

• Jež je polako prešao stazu i je otišao u travu.

But that sounds unnatural in standard Croatian. With coordinated past verbs, Croatian usually does not repeat the auxiliary unless there is a special stylistic reason.

Because they agree with the subject jež, which is masculine singular.

In Croatian, the past participle changes depending on the gender and number of the subject.

Here:

• jež = masculine singular
• therefore: prešao, otišao

Compare:

• masculine singular: prešao, otišao
• feminine singular: prešla, otišla
• neuter singular: prešlo, otišlo
• plural masculine/mixed: prešli, otišli

So the ending is not random; it matches the subject.

Because stazu is the accusative singular form of staza.

Here stazu is the direct object of prešao:

• preći stazu = to cross a path

Many feminine nouns ending in -a change like this:

• nominative: staza
• accusative: stazu

The same pattern appears in many other nouns:

• žena → ženu
• kuća → kuću
• trava → travu

Because Croatian uses different cases after u depending on whether you mean:

• movement into something → accusative
• location inside something → locative

So:

• u travu = into the grass → motion, so accusative
• u travi = in the grass → location, so locative

In this sentence, the hedgehog is moving into the grass, so u travu is the correct form.

Yes. Both are perfective, which means they present the actions as completed whole events.

• preći → to cross (successfully, completely)
• otići → to go away / leave

In the sentence, the actions are seen as finished:

1. the hedgehog crossed the path
2. then it went into the grass

This is why the sentence sounds like a completed little sequence of events.

Polako is an adverb, meaning slowly.

It describes how the hedgehog crossed the path:

• Jež je polako prešao stazu... = the hedgehog crossed the path slowly

In context, it can also color the whole scene, but grammatically it most directly modifies prešao.

Not completely. Croatian word order is fairly flexible, but there are important patterns.

This sentence has a very natural order:

• Jež je polako prešao stazu i otišao u travu.

One important point is that je is a clitic, and clitics tend to stand in second position in the sentence or clause.

That is why jež je sounds natural:

• Jež je...

You can move other parts for emphasis, but not everything is equally natural. For example:

• Polako je jež prešao stazu... puts more emphasis on polako
• Stazu je jež polako prešao... emphasizes stazu

So the sentence can be rearranged, but the original version is the most neutral and natural.

Because Croatian usually does not need subject pronouns when the subject is already clear.

Here the subject is explicitly named:

• Jež = the hedgehog

So there is no need to add on (he).

Croatian often leaves pronouns out even when the subject is not stated as a noun, because the verb form usually makes the meaning clear enough from context.

A helpful rough guide for an English speaker:

• jež ≈ yezh

  • j sounds like English y
  • ž sounds like the s in measure

• prešao ≈ preh-shao

  • š sounds like English sh

• otišao ≈ oh-tee-shao

A few useful letter values from this sentence:

• j = y
• ž = sound like s in measure
• š = sh

Croatian spelling is quite regular, so once you know the letter sounds, pronunciation becomes much easier.

It usually has the sense of went away, left, or departed.

So otišao u travu is not just neutral movement; it suggests the hedgehog went off into the grass.

That is why otići often feels a bit stronger than a simple English go. It often implies leaving one place and ending up elsewhere.
