Izvor je blizu planinarskog doma.

Je is the 3rd person singular form of the verb biti (to be), so it means is.

So the sentence structure is:

• Izvor = the spring / water source
• je = is
• blizu planinarskog doma = near the mountain lodge

Literally: The spring is near the mountain lodge.

Serbian normally does not use articles like the or a/an.

So:

• izvor can mean a spring or the spring
• planinarski dom can mean a mountain lodge or the mountain lodge

The exact meaning depends on context. In this sentence, English usually translates it as the spring is near the mountain lodge, but Serbian does not need separate article words.

Because blizu usually requires the genitive case in Serbian.

The base form is:

• planinarski dom = mountain lodge

But after blizu (near), it changes to genitive:

• planinarskog doma

So:

• blizu planinarskog doma = near the mountain lodge

This is a very common pattern. Other words and expressions of location or relation can also require the genitive.

It is the genitive singular.

Here is the breakdown:

• planinarski dom = nominative singular
• planinarskog doma = genitive singular

Both words change because the adjective must agree with the noun:

• planinarski → planinarskog
• dom → doma

That agreement in case, number, and gender is a key feature of Serbian grammar.

Because Serbian adjectives must agree with the noun they describe.

Since dom becomes doma in the genitive singular, the adjective planinarski must also change to the matching genitive singular masculine/neuter form:

• nominative: planinarski dom
• genitive: planinarskog doma

So the adjective changes because the noun changes.

Planinarski dom literally means something like mountaineers’ home, but in natural English it is usually translated as:

• mountain lodge
• hikers’ lodge
• mountaineering lodge

It refers to a building used by hikers or climbers, often in the mountains.

Yes. Izvor can mean:

• spring / water source
• source in a more abstract sense, depending on context

For example, in another sentence it could mean source of information or origin of something. But in this sentence, with blizu planinarskog doma, it most naturally means a natural spring.

Yes, Serbian word order is more flexible than English word order.

The neutral, natural order here is:

• Izvor je blizu planinarskog doma.

But other orders are possible for emphasis, such as:

• Blizu planinarskog doma je izvor.
  = Near the mountain lodge is a spring / The spring is near the mountain lodge.

The meaning stays basically the same, but the emphasis changes. The original sentence is the most straightforward and neutral.

Serbian has a tendency for certain short unstressed words, called clitics, to appear near the beginning of the sentence, often in the second position.

In this sentence:

• Izvor = first element
• je = clitic in second position

So Izvor je... sounds natural and standard.

This second-position behavior is very common with forms like:

• je
• sam
• si
• smo
• ste
• su

It can be thought of as functioning like a preposition-like word here, because it is followed by a noun phrase in the genitive:

• blizu planinarskog doma

Learners often just memorize it as:

• blizu + genitive = near

That is the most useful practical rule.

You may also see blizu used more adverbially in other contexts, but in sentences like this, treating it as a word that governs the genitive is the easiest approach.

For close to / near, Serbian commonly uses:

• Izvor je blizu planinarskog doma.

For far from, you can use:

• Izvor je daleko od planinarskog doma.

Notice the pattern:

• blizu + genitive
• daleko od + genitive

So:

• planinarskog doma stays in the genitive
• with daleko, you usually also use od

Yes, but the meaning is slightly different.

• blizu planinarskog doma = near the mountain lodge
• kod planinarskog doma = by / at / near the mountain lodge

Kod often suggests being at someone's place, by, or in the vicinity of something. In many contexts the meanings overlap, but blizu is the more direct translation of near.

In its basic form, dom ends in a consonant, which is a common pattern for masculine nouns in Serbian.

That matters because it affects:

• adjective agreement: planinarski
• case endings: doma in the genitive singular

So the phrase follows masculine singular patterns:

• planinarski dom
• planinarskog doma

It is mainly talking about location.

It tells you where the spring is:

• The spring is near the mountain lodge.

If the focus were more on existence, Serbian might use a different structure in some contexts, but here the sentence simply describes the spring’s position relative to the lodge.
