Questions & Answers about 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
