Rano ujutro je rosa na travi, pa su mi tenisice mokre.

They do different jobs:

• rano = early
• ujutro = in the morning

So rano ujutro means early in the morning.

This is a very common time expression in Croatian. It is not redundant; it works just like English early in the morning.

Ujutro is a fixed adverb meaning in the morning. Learners often expect u jutro, because u usually means in, but here Croatian normally uses the adverb ujutro as one word.

Compare:

• ujutro = in the morning
• navečer = in the evening
• noću = at night

So in this sentence, rano ujutro is just a standard adverbial phrase.

Because je is a clitic, and Croatian clitics usually go near the beginning of the clause, typically after the first phrase or unit.

So:

• Rano ujutro je rosa na travi.

is natural because rano ujutro is the first unit, and then the clitic je comes after it.

English speakers often expect something more like:

• Rosa je na travi rano ujutro.

That is also understandable, but the given version sounds more natural for the intended flow of information: first the time, then the situation.

Croatian does not need a dummy subject like English there.

English says:

• There is dew on the grass.

Croatian often simply says:

• Rosa je na travi.
• literally: Dew is on the grass.

So yes, the Croatian structure is closer to dew is on the grass than to English there is dew on the grass.

Travi is in the locative singular.

That is because na can take different cases depending on meaning:

• na travi = on the grass → location, so locative
• na travu = onto the grass → movement toward a surface, so accusative

In this sentence, the dew is already located on the grass, so na travi is correct.

Here pa means something like:

• so
• and so
• therefore
• as a result

So the sentence means:

• There is dew on the grass, so my sneakers are wet.

Pa is very common in everyday Croatian. It often links one fact to its consequence in a very natural, conversational way.

Mi is the unstressed dative form of ja, meaning to me.

Literally, the phrase is something like:

• the sneakers are wet to me

But in natural English, that means:

• my sneakers are wet

Croatian very often uses the dative like this to show possession, especially with things closely connected to a person.

So:

• su mi tenisice mokre = my sneakers are wet

Because Croatian clitics follow a fixed order.

Both su and mi are clitics here:

• su = are
• mi = to me / my

In standard word order, the auxiliary/copula clitic comes before the dative clitic, so:

• su mi

is the normal order.

Because tenisice means sneakers / trainers, and in normal use you usually talk about the pair.

Croatian does have a singular:

• tenisica = one sneaker

But very often the plural is used because footwear naturally comes in pairs.

So:

• tenisice su mokre = the sneakers are wet

Because the adjective must agree with tenisice.

Tenisice is:

• feminine
• plural

So the adjective must also be feminine plural:

• mokre

Compare:

• mokra tenisica = a wet sneaker
• mokre tenisice = wet sneakers

Yes, absolutely.

• Moje tenisice su mokre. = My sneakers are wet.
• Su mi tenisice mokre. = also My sneakers are wet.

The version with mi is very natural and common in Croatian, especially in everyday speech.

A rough difference:

• moje tenisice explicitly says my sneakers
• mi tenisice expresses possession more indirectly, often sounding a bit lighter and more conversational

Both are correct.

Yes. Croatian word order is fairly flexible, and changing the order changes the emphasis more than the basic meaning.

For example:

• Rano ujutro je rosa na travi, pa su mi tenisice mokre.
  Focus begins with the time.

• Na travi je rano ujutro rosa, pa su mi tenisice mokre.
  Focus begins with the location.

• Rosa je rano ujutro na travi, pa su mi tenisice mokre.
  Also possible, but the rhythm and emphasis are different.

So the original sentence is not the only possible order, but it is a natural one.
