Moj brat je očigledno umoran.

Word by word:

• moj = my
• brat = brother
• je = is (3rd person singular of biti, to be)
• očigledno = obviously / evidently / apparently
• umoran = tired

So the structure is very close to English: My brother is obviously tired.

Because moj has to agree with brat.

Brat is:

• masculine
• singular
• here in the nominative case

So the possessive adjective also appears in the masculine singular nominative form:

• moj brat = my brother
• moja sestra = my sister
• moje dete = my child

It is in the nominative case, because it is the subject of the sentence.

The basic subject form is used because my brother is the person being described.

So:

• moj brat = nominative, subject
• je umoran = tells us something about the subject

There isn’t one, because Serbian does not have articles like English a/an/the.

So brat can mean:

• brother
• a brother
• the brother

The exact meaning depends on context. In this sentence, moj brat naturally means my brother without needing any article.

Je is the present-tense form of biti (to be) for he/she/it.

Here it links the subject to the description:

• Moj brat = subject
• je = is
• umoran = description

So je works exactly like is in English.

Because umoran is an adjective, and it agrees with the subject.

Since brat is:

• masculine
• singular

the adjective must also be:

• masculine
• singular

Compare:

• brat je umoran = the brother is tired
• sestra je umorna = the sister is tired
• dete je umorno = the child is tired

Yes. It is still an adjective.

In this sentence it is a predicate adjective, meaning it describes the subject after the verb to be.

So:

• umoran brat = a tired brother → adjective before the noun
• brat je umoran = the brother is tired → adjective used predicatively

Both use the adjective umoran, but in different sentence positions.

Here očigledno is an adverb. It means something like:

• obviously
• evidently
• sometimes apparently, depending on context

It comments on the whole statement: it is obvious that my brother is tired.

A useful thing to notice: očigledno does not change form here. Unlike adjectives, adverbs like this are typically invariable.

Yes, Serbian word order is fairly flexible, so očigledno can often move.

For example:

• Moj brat je očigledno umoran.
• Očigledno je moj brat umoran.
• Moj brat je umoran, očigledno.

These versions are similar, but the emphasis changes slightly.

The most neutral version is the one you were given: Moj brat je očigledno umoran.

Because je is a clitic in Serbian.

Clitics are short unstressed words that usually go in a special position, often near the beginning of the sentence or clause, typically after the first stressed element.

That is why:

• Moj brat je očigledno umoran. sounds natural.
• Očigledno je moj brat umoran. also works.

But something like:

• Moj brat očigledno je umoran

is much less natural in standard neutral Serbian, because the clitic je is not in its usual position.

Because Serbian often does not need subject pronouns when the subject is already stated clearly.

Here, moj brat already tells us who we are talking about, so there is no need to add on (he).

In fact, adding on here would usually sound unnecessary unless you want special emphasis.

Not always exactly.

Depending on context, očigledno can feel like:

• obviously
• clearly
• evidently
• apparently

In some situations, English obviously can sound stronger or more conversational, while očigledno may sound a bit more like it is evident / it seems clear.

So the best translation depends on tone and context, even though obviously is a very good basic translation.

A simple pronunciation guide:

• moj ≈ moy
• brat ≈ braht
• je ≈ ye
• očigledno ≈ o-CHI-gled-no
• umoran ≈ u-MO-ran

A few letter notes:

• j is pronounced like English y in yes
• č is like ch in church
• o is a clear pure o, not a diphthong like in some English accents

So the whole sentence is roughly: moy braht ye o-CHI-gled-no u-MO-ran

Yes, grammatically you can.

But the meaning changes:

• Moj brat je očigledno umoran = My brother is obviously tired
• Brat je očigledno umoran = The brother / brother is obviously tired, depending on context

Without moj, you lose the idea of possession (my). Whether it still sounds natural depends on the situation.
