Stari stroj više ne propušta vodu.

In this sentence, više ne means no longer or not anymore.

A very useful pattern is:

• više ne + verb = no longer + verb

So:

• više ne propušta = no longer leaks / doesn’t leak anymore

On its own, više often means more, but with ne it very often has this not anymore / no longer meaning.

Because više ne works as a common unit meaning no longer.

So the most neutral wording is:

• Stari stroj više ne propušta vodu.

Croatian word order is fairly flexible, and you may also hear things like:

• Stari stroj ne propušta više vodu.

That can also mean The old machine doesn’t leak water anymore, but više ne + verb is the clearest standard pattern for learners to remember.

Stari is the adjective old, and it agrees with stroj in:

• gender: masculine
• number: singular
• case: nominative

Because stroj is masculine singular and is the subject of the sentence, the adjective must match it:

• stari stroj = old machine

You may also come across star, but stari is the form learners will very commonly see before a masculine singular noun in this kind of sentence.

Because vodu is the accusative singular form of voda.

• voda = nominative, dictionary form
• vodu = accusative, used here for the direct object

The machine is doing something to the water, so water is the object of the verb:

• propušta vodu = leaks water / lets water through

This is a very common pattern with feminine nouns ending in -a:

• nominative -a
• accusative singular -u

Propušta is:

• present tense
• 3rd person singular

It matches the subject stari stroj = the old machine / it.

So literally:

• stroj propušta = the machine leaks / lets through

Here propušta means something like:

• leaks
• lets through
• allows to pass through

With vodu, the natural English translation is usually leaks water.

So propuštati is broader than just to leak. Depending on context, it can mean to let something through in a more general sense.

Yes. That is a very close, more literal translation.

Croatian propuštati can describe the idea of something passing through when it should not. In natural English, when the object is water, we often translate that as to leak.

So both are possible:

• The old machine no longer leaks water.
• The old machine no longer lets water through.

The first is usually the more natural everyday English version.

Because the two verbs are similar, but not identical.

• curiti / curi = to drip, run, leak
• propuštati / propušta = to let through, leak

Curi focuses more on the liquid actually flowing or dripping. Propušta focuses more on the object being faulty and allowing something through.

So:

• Stroj curi. = The machine is leaking.
• Stroj propušta vodu. = The machine lets water through / leaks water.

Both can be correct, but propušta vodu highlights the idea of a bad seal or barrier.

Yes. Propuštati is the imperfective verb.

That fits well because the sentence describes an ongoing state or repeated behavior:

• the machine used to leak / had the problem
• now it no longer does

Croatian often uses the imperfective present for things like habits, general truths, or ongoing conditions. A perfective verb would not sound right here for this general it no longer leaks meaning.

Because Croatian has no articles like the or a/an.

So:

• stari stroj can mean the old machine
• or an old machine

The exact meaning depends on context. In this sentence, English will usually use the old machine, but Croatian does not need a separate word for that.

Not always, but it is a very common and standard word for machine.

Depending on context, Croatian might also use other words, such as:

• uređaj = device
• mašina = often machine, but more colloquial or context-dependent

Here stroj is a perfectly normal choice.

A simple learner-friendly pronunciation guide is:

• Stari = STAH-ree
• stroj = stroi (roughly one syllable)
• više = VEE-sheh
• ne = neh
• propušta = pro-POOSH-tah
• vodu = VOH-doo

A useful sound note:

• š sounds like sh in ship

So više and propušta both contain that sh sound.
