Ovo je voda za piće.

Ovo means this and points to something near the speaker, so it is natural if you are indicating a specific thing: a glass, a bottle, a tap, and so on.

• Ovo je voda za piće. = This is drinking water.
• To je voda za piće. = That is drinking water. / That’s drinking water.

In real speech, ovo and to can sometimes overlap a bit, but the basic idea is this vs that.

You could also say just Voda za piće. on a sign or label, where the full sentence is not necessary.

Je is the normal 3rd person singular present form of biti (to be) in an unstressed position.

So:

• ovo je = this is

Croatian often uses short unstressed forms, called clitics, in ordinary sentences. You will hear je all the time in sentences like this.

A longer form like jest exists, but it is usually used for emphasis, contrast, or in more formal/stylistic situations. In a simple neutral sentence, je is the normal choice.

Because voda is the predicate noun after je, and here it stays in the nominative case.

Structure:

• Ovo = subject-like element
• je = is
• voda = water

So Croatian uses:

• Ovo je voda.

not

• Ovo je vodu.

Vodu would be accusative, which would be used in other roles, for example:

• Pijem vodu. = I drink water.

Here za means for, expressing purpose: for drinking.

With this meaning, za takes the accusative case.

So in:

• voda za piće

the noun after za is in the accusative.

A useful detail: piće is a neuter noun, and its nominative and accusative singular forms are the same, so you do not see a visible change here.

That is why it looks like:

• nominative: piće
• accusative: piće

Grammatically, piće is a noun derived from the verb piti (to drink). In many contexts it means a drink / beverage:

• Hladno piće = a cold drink

But in the phrase za piće, it is best understood as for drinking.

So voda za piće is a standard way to say water intended for drinking, not just any water.

This is one of those places where Croatian uses a noun where English often prefers an -ing form.

Yes, pitka voda is also very common.

• voda za piće = water for drinking
• pitka voda = drinkable / potable water

The difference is mostly about style and focus:

• voda za piće stresses purpose/use
• pitka voda stresses the quality of being safe/suitable to drink

In many practical contexts, they are very close in meaning. On signs, public notices, and technical contexts, both can appear.

Croatian does not have articles like English a/an and the.

So voda can mean:

• water
• the water
• sometimes even some water

The exact meaning depends on context.

That is very normal in Croatian. Learners often want to insert an article mentally, but Croatian simply does not require one.

A simple approximation is:

• Ovo je voda za piće
• roughly: OH-vo yeh VO-da za PEE-chyeh

A few pronunciation notes:

• j in Croatian sounds like English y in yes
• č and ć are different letters, though many learners hear them as similar at first
• ć is a softer sound than č

For many English speakers, ć in piće can be approximated as a soft ch, though that is not perfect. The important thing at first is to avoid pronouncing it like English k or s.

Also, Croatian spelling is very regular, so once you learn the sound values, pronunciation becomes much easier.

The neutral word order here is:

• Ovo je voda za piće.

That is the most natural version in most situations.

You can change word order in Croatian, but it usually changes emphasis rather than basic meaning. For example, other orders might sound marked, contrastive, or context-dependent.

For a beginner, it is best to learn this sentence exactly as written and use this order as your default.

This is a very common question, because voda is feminine, but the sentence uses ovo, which looks neuter.

The reason is that ovo does not directly agree with voda here. It stands on its own as this, pointing to some thing or situation being identified.

So:

• Ovo je voda. = This is water.

That is correct even though voda is feminine.

If you were directly modifying the noun voda, then you would need feminine agreement:

• ova voda = this water

So compare:

• Ovo je voda. = This is water.
• Ova voda je hladna. = This water is cold.

That difference is very useful to learn early.

It is natural, but it most strongly sounds like something you would say when identifying water or marking it as suitable for drinking.

Typical contexts:

• on a sign near a tap
• in instructions
• when clarifying which water is safe to drink
• when pointing at a container

In ordinary conversation, people might also simply say:

• Ova voda je pitka. = This water is drinkable.
• To je voda za piće. = That’s drinking water.

So the sentence is perfectly normal, but it has a slightly practical, informative feel.
