Moje telo je umorno.

Because telo is a neuter singular noun in Serbian.

The possessive moj (my) changes form to match the noun it describes:

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

So:

• moj brat = my brother
• moja ruka = my hand
• moje telo = my body

The possessive agrees with the thing owned, not with the speaker.

For the same reason: it agrees with telo, which is neuter singular.

The adjective umoran (tired) changes by gender:

• umoran = masculine singular
• umorna = feminine singular
• umorno = neuter singular

So:

• On je umoran. = He is tired.
• Ona je umorna. = She is tired.
• Dete je umorno. = The child is tired.
• Moje telo je umorno. = My body is tired.

Yes. Telo (body) is a neuter noun in Serbian.

A lot of Serbian neuter nouns end in -o or -e, and telo is one of them. Because it is neuter, words connected to it usually also take neuter forms, like:

• moje telo
• umorno telo
• ovo telo

Je is the 3rd person singular present form of the verb biti (to be).

So in this sentence:

• Moje telo = my body
• je = is
• umorno = tired

Together: My body is tired.

Serbian often uses forms of biti the way English uses am / is / are.

Normally, no. In a standard sentence like this, je is needed:

• Moje telo je umorno.

Without it, Moje telo umorno sounds incomplete or nonstandard.

Serbian can sometimes omit forms of to be in very informal speech, headlines, poetry, or certain special structures, but for a learner, it is best to keep je here.

Not usually.

Moje telo je umorno literally means My body is tired, and it sounds more specific or more emphatic, as if you are focusing on your body physically.

If you simply want to say I am tired, Serbian normally uses:

• Umoran sam. = I am tired. (male speaker)
• Umorna sam. = I am tired. (female speaker)

So this sentence is grammatical and understandable, but it is not the most common everyday way to say you are tired.

Yes, and that can sound quite natural.

• Telo mi je umorno.

Here, mi means to me / my in a dative clitic construction that often expresses possession. Serbian frequently uses this pattern instead of a possessive adjective.

So both can work:

• Moje telo je umorno.
• Telo mi je umorno.

The second version can sound a bit more conversational in some contexts.

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

The neutral order is:

• Moje telo je umorno.

But depending on emphasis, you might also hear:

• Umorno je moje telo.
• Moje je telo umorno.

These alternatives are possible, but the original version is the most straightforward for learners.

The main words are in the nominative because moje telo is the subject of the sentence.

• moje agrees with telo
• telo is nominative singular
• umorno is a predicate adjective agreeing with the subject

So this is a simple subject + to be + adjective structure.

A simple approximate pronunciation is:

• MO-ye TE-lo ye oo-MOR-no

A few notes:

• j in Serbian is pronounced like English y in yes
• je sounds roughly like ye
• stress is not usually marked in normal writing, so learners often just imitate native speech

If written in Cyrillic, the sentence is:

• Моје тело је уморно.

In this sentence, the difference is purely grammatical agreement.

The basic meaning is the same: tired.

• umoran matches masculine nouns
• umorna matches feminine nouns
• umorno matches neuter nouns

So:

• Čovek je umoran. = The man is tired.
• Žena je umorna. = The woman is tired.
• Telo je umorno. = The body is tired.

Because Serbian is an inflected language, and words often change form to show grammatical relationships.

In English, my stays the same:

• my brother
• my sister
• my body

In Serbian, the possessive changes to match gender, number, and case:

• moj brat
• moja sestra
• moje telo

This is very normal in Serbian and something learners get used to over time.

Yes. Telo means body, and depending on context it can mean:

• a person’s body
• a physical body
• a body as an object or mass
• sometimes even a formal or technical body in expressions like a governing body, though that depends on context

In Moje telo je umorno, it clearly means my physical body.
