Volim toplo vreme, ali ne volim kišu.

Because Serbian often leaves out subject pronouns when the verb ending already shows who the subject is.

• Volim = I like
• The ending -im tells you it is 1st person singular

So Volim toplo vreme already means I like warm weather. You could add ja and say Ja volim..., but that usually adds emphasis.

Ali means but.

So the sentence has two parts:

• Volim toplo vreme = I like warm weather
• ali ne volim kišu = but I do not like rain

Serbian usually makes a verb negative by putting ne before it.

• volim = I like
• ne volim = I do not like

In standard writing, ne is usually written as a separate word with verbs like this.

Yes, Serbian often repeats the verb for clarity and balance, especially with ali.

• Volim toplo vreme, ali ne volim kišu. = full and very natural
• Volim toplo vreme, ali ne kišu. = possible, but more elliptical

For learners, the repeated verb is easier and clearer.

Because kiša is the direct object of volim, and direct objects often go into the accusative case.

The noun changes like this:

• kiša = rain, nominative
• kišu = rain, accusative singular

This is a very common pattern for feminine nouns ending in -a:

• nominative singular: -a
• accusative singular: -u

Because vreme is a neuter noun, and in Serbian the nominative and accusative singular are often the same for neuter nouns.

So:

• vreme = time / weather
• as the object after volim, it still stays vreme

By contrast, kiša is feminine, so it changes to kišu in the accusative.

Because the adjective has to agree with the noun in gender, number, and case.

• vreme is neuter singular
• so the adjective must also be neuter singular
• that gives toplo

The basic adjective is:

• topao = warm/hot (masculine)
• topla = warm/hot (feminine)
• toplo = warm/hot (neuter)

So toplo vreme means warm weather.

Yes. Vreme can mean both time and weather in Serbian.

Context tells you which meaning is intended. In this sentence, toplo vreme clearly means warm weather, not warm time.

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

So Volim toplo vreme can mean:

• I like warm weather
• or, depending on context, I like the warm weather

Usually the context makes the meaning clear.

Not completely. Serbian word order is more flexible than English word order.

The given sentence is very natural:

• Volim toplo vreme, ali ne volim kišu.

But you could also say:

• Ne volim kišu, ali volim toplo vreme.

That changes the emphasis a little, but the meaning stays basically the same.

A rough English-style pronunciation is:

VO-lim TO-plo VRE-me, A-li ne VO-lim KEE-shu.

A few useful pronunciation notes:

• š sounds like sh in shoe
• kišu sounds roughly like KEE-shu
• Serbian spelling is quite phonetic, so words are usually pronounced much as they are written

In Serbian Cyrillic, it is:

Волим топло време, али не волим кишу.

Serbian normally uses both scripts, Latin and Cyrillic, and they match very closely letter for letter.
