Moja ulica je blizu parka.

Because ulica is a feminine singular noun, and Serbian possessive words like moj have to agree with the noun they describe.

So:

• moj = masculine singular
• moja = feminine singular
• moje = neuter singular

Since ulica is feminine, you say moja ulica.

A few parallels:

• moj grad = my city
• moja kuća = my house
• moje selo = my village

Ulica is in the nominative case because it is the subject of the sentence.

In Moja ulica je blizu parka, the thing being described is moja ulica. The sentence is saying something about your street, so it stays in the nominative.

• moja ulica = the subject
• je blizu parka = what is being said about it

Because blizu normally requires the genitive case.

The base form is:

• park = park

But after blizu, it changes to the genitive:

• blizu parka = near the park

This is a very common pattern in Serbian. Some location-related words require a specific case, and blizu is one of them.

More examples:

• blizu škole = near the school
• blizu kuće = near the house
• blizu grada = near the city

In learner-friendly terms, it is best to think of blizu here as a word meaning near/close to that is followed by the genitive.

You will often see it used like a preposition:

• blizu parka
• blizu škole
• blizu centra

It can also behave adverbially in some contexts, but for this sentence the most useful thing to remember is:

• blizu + genitive

Because Serbian does not have articles like a and the.

So park can mean a park or the park, depending on context, and parka here can mean of a park or of the park, again depending on context.

In this sentence, English naturally uses the park, but Serbian does not need a separate word for the.

Context usually makes it clear.

Yes. Just like in English, my street usually means the street where I live, not a street you literally own.

So moja ulica is completely natural and usually refers to:

• the street I live on
• the street associated with me

It does not normally suggest ownership in a legal sense.

Normally, no. In standard Serbian, the present tense of biti (to be) is usually expressed, so you say:

• Moja ulica je blizu parka.

Leaving out je would sound incomplete in ordinary standard speech.

Serbian sometimes omits forms of to be in special styles like headlines, notes, or very informal speech, but for normal full sentences, keep je.

No, Serbian word order is fairly flexible, although some orders sound more neutral than others.

The most neutral version here is:

• Moja ulica je blizu parka.

But other orders are possible, for example:

• Blizu parka je moja ulica.

This changes the emphasis a bit. That version highlights blizu parka more strongly, as if answering Where is your street?

So the words can move around, but the most natural beginner version is the original one.

Both words show it:

• moja = feminine singular
• ulica = singular noun form

If it were plural, you would need plural agreement, for example:

• moje ulice = my streets

So the sentence clearly refers to one street.

Not exactly.

• blizu parka = near the park
• kod parka = by the park / at the park / near the park, depending on context

Sometimes they can be similar in meaning, but blizu is the clearer, more direct way to say near.

So for a straightforward translation of My street is near the park, blizu parka is the best choice.
