Druga soba je mala.

Because soba is a feminine singular noun, and Serbian adjectives must agree with the noun in gender, number, and case.

So here:

• druga = feminine singular
• soba = feminine singular
• mala = feminine singular

That is why all three match.

Compare:

• drugi sto je mali = the second table is small
• drugo selo je malo = the second village is small

Je means is. It is the 3rd person singular present form of biti = to be.

So:

• ja sam = I am
• ti si = you are
• on/ona/ono je = he/she/it is

In Druga soba je mala, je links the subject druga soba with the description mala, just like is in English.

Because je is a clitic in Serbian. Clitics usually go in the second position of the sentence or clause, not necessarily after the first single word.

Here, Druga soba acts as the first unit, so je comes after that whole phrase:

• Druga soba je mala.

This is normal Serbian word order.

It can mean either, depending on context.

Common meanings of drugi/druga/drugo include:

• second
• other
• another

So druga soba can mean:

• the second room
• the other room
• another room

The exact meaning depends on the situation. Since the learner already has the sentence meaning, this is just a useful thing to know about the word druga.

Because Serbian does not have articles like English the and a/an.

So soba can mean:

• a room
• the room

The listener understands which one is meant from context.

That is why Druga soba je mala has no separate word for the.

It is in the nominative singular.

Why?

• soba is the subject of the sentence
• subjects are normally in the nominative

The adjectives druga and mala also appear in nominative singular because they agree with soba.

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

The sentence:

• Druga soba je mala.

is a neutral, natural way to say it.

But other orders are possible for emphasis, for example:

• Mala je druga soba.
• Druga je soba mala.

These versions are more marked and may sound emphatic, contrastive, or stylistically different. A beginner should usually stick with:

• Druga soba je mala.

A simple approximate pronunciation is:

• DROO-ga SO-ba ye MA-la

A few helpful notes:

• j in Serbian sounds like English y
• so je sounds like ye
• every written letter is normally pronounced
• Serbian spelling is quite phonetic

So Druga soba je mala is pronounced very close to the way it is written.

Usually, yes: nouns ending in -a are often feminine in Serbian, and soba is feminine.

That is why the adjectives take feminine forms:

• druga
• mala

But it is good to remember that -a does not guarantee femininity in every single case in Serbian. It is a strong pattern, not an absolute rule. Here, though, soba is definitely feminine.
