Odvodno crijevo može propuštati.

Literally, odvodno crijevo means drain hose or outflow hose.

• odvodno = draining, outlet, discharge-related
• crijevo = hose, pipe, tube

In everyday appliance-related Croatian, crijevo is often used for a flexible hose.

Because crijevo is a neuter noun, and the adjective has to agree with it in gender, number, and case.

Here the noun is:

• crijevo = neuter singular nominative

So the adjective must also be neuter singular nominative:

• odvodno

Compare:

• odvodni kabel = drainage/outlet cable (masculine)
• odvodna cijev = drainage pipe (feminine)
• odvodno crijevo = drainage hose (neuter)

It is in the nominative singular.

That is because it is the subject of the sentence:

• Odvodno crijevo može propuštati.
• The drain hose can leak.

The thing doing the action is the hose, so nominative is used.

Može is the 3rd person singular present tense of moći, which means can, be able to, or sometimes may.

So:

• može = can / may / is able to

In this sentence it expresses possibility:

• Odvodno crijevo može propuštati.
• The drain hose may/can be leaking.

Because može propuštati means can/may leak or might be leaking, while propušta means leaks / is leaking more directly.

The difference is:

• propušta = it leaks / it is leaking
• može propuštati = it may leak / it might be leaking / it can leak

So the version with može adds uncertainty or possibility rather than stating the leak as a fact.

Propuštati can mean to let through, to leak, or to allow to pass, depending on context.

In the context of a hose, it means:

• to leak
• literally, to let liquid pass through when it should not

So here:

• crijevo propušta = the hose is leaking

Because it comes after može.

In Croatian, modal verbs like moći are followed by an infinitive, just like in English:

• can leak
• može propuštati

Other examples:

• Mogu doći. = I can come.
• Može raditi. = It can work.
• Možemo čekati. = We can wait.

Yes, propuštati is imperfective.

That matters because imperfective verbs are often used for:

• ongoing actions
• repeated actions
• general situations

A leak is often understood as something ongoing or continuing, so propuštati is very natural here.

Its perfective partner is often propustiti, but that usually does not fit this context as well. Propustiti often means something like let through once, miss, or allow through, depending on context.

So for a hose leaking, propuštati is the normal choice.

Yes, literally propuštati can mean let through, but in this context the natural meaning is leak.

Because the subject is a drain hose, a native speaker will normally understand:

• Odvodno crijevo može propuštati. = The drain hose may be leaking.

Context makes the meaning clear.

Yes, often that is a very natural translation.

Depending on context, the sentence could be translated as:

• The drain hose can leak.
• The drain hose may leak.
• The drain hose might be leaking.

If this appears in troubleshooting instructions, might be leaking is often the most natural English version.

Yes, Croatian word order is fairly flexible.

The neutral order here is:

• Odvodno crijevo može propuštati.

But other orders are possible for emphasis, for example:

• Može propuštati odvodno crijevo.

That sounds more marked and less neutral. In most learning contexts, the original order is the best one to use.

A rough pronunciation guide is:

• crijevo ≈ TSRYEH-vo

A bit more carefully:

• cr at the start is a consonant cluster; the r is pronounced clearly
• ije sounds roughly like yeh
• stress is commonly placed near the first part: crìjevo or close to CRI-ye-vo, depending on accent

If you are an English speaker, the hardest part is usually the beginning cr cluster.

It can mean different things depending on context.

Common meanings include:

• hose
• tube
• intestine / bowel

So by itself, crijevo can be ambiguous. But with odvodno, the meaning is clearly something like drain hose.

Yes, but it is not exactly the same.

• crijevo usually suggests a flexible hose
• cijev usually suggests a pipe or more rigid tube

So:

• Odvodno crijevo može propuštati. = The drain hose may be leaking.
• Odvodna cijev može propuštati. = The drain pipe may be leaking.

Both are correct, but they refer to slightly different objects.

Yes, absolutely.

The verb propuštati does not need an object here because the meaning to leak is already complete in context.

So this is a fully natural and complete sentence:

• Odvodno crijevo može propuštati.

English works similarly:

• The hose may be leaking.

No extra object is necessary.
