Na spisku su brašno i ulje.

In Serbian, the natural expression for on the list is na spisku.

• na = on
• spisak = list
• after na in this meaning, Serbian uses the locative case
• spisak becomes spisku

So:

• na spisku = on the list

Even though English and Serbian do not always match word-for-word with prepositions, this is the normal idiomatic choice in Serbian.

Because it is in the locative singular, required by na in this sentence.

The basic form is:

• spisak = list

After na with the meaning of location, it changes to:

• na spisku = on the list

This is a common masculine noun pattern:

• nominative: spisak
• locative: spisku

So the ending changes because of case, not because the meaning of the noun itself changes.

Su is the 3rd person plural present form of biti (to be).

The subject of the sentence is:

• brašno i ulje = flour and oil

That is a compound subject made of two things, so Serbian uses the plural verb:

• su = are

That is why the sentence has su, not je.

Because together they form a plural idea: flour and oil.

Compare:

• Brašno je na spisku. = Flour is on the list.
• Ulje je na spisku. = Oil is on the list.
• Brašno i ulje su na spisku. = Flour and oil are on the list.

So even though each noun is singular by itself, two singular nouns joined by i usually take a plural verb.

Both are possible, but they sound a little different in focus.

• Na spisku su brašno i ulje.
  This puts emphasis first on the list or answers a question like What is on the list?

• Brašno i ulje su na spisku.
  This starts with the items themselves and can answer a question like Where are flour and oil?

There is also a grammar reason: su is a short form of to be, and these short forms often come in the second position of the sentence or clause. Since Na spisku comes first, su follows it.

Because they are in the nominative case, which is the case normally used for the subject of the sentence.

Here, brašno i ulje are the things that are on the list, so they are the subject.

Basic forms:

• brašno = flour
• ulje = oil

In this sentence, those base forms are exactly what Serbian needs.

They are grammatically singular.

• brašno is singular
• ulje is singular

But these are often used like mass nouns, similar to English flour and oil, where you are talking about the substance in general, not individual countable objects.

So:

• brašno = flour
• ulje = oil

If you join them with i (and), the whole subject becomes plural for verb agreement, which is why you get su.

Both are neuter nouns.

A useful clue is their endings:

• brašno ends in -o
• ulje ends in -e

Those endings are very often neuter in Serbian.

That matters because adjective forms and some other words may need to agree with them. For example:

• dobro brašno = good flour
• dobro ulje = good oil

Here, though, no adjective is used, so you just need to recognize them as neuter singular nouns.

Yes. That is also natural.

• spisak = list
• lista = list

So:

• Na spisku su brašno i ulje.
• Na listi su brašno i ulje.

Both can mean Flour and oil are on the list.

There can be small differences in style or preference depending on context, but for a learner, both are good and understandable.

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

So spisak can mean:

• a list
• the list

The exact meaning depends on context.

In Na spisku su brašno i ulje, English naturally uses the list, but Serbian does not need a separate word for that.

A common point of difficulty is lj in ulje.

• ulje is pronounced roughly like OOL-ye
• lj is a single Serbian sound, not a full English l plus j

It is similar to the lli sound in some pronunciations of million, though not exactly the same for every English speaker.

Also:

• brašno is roughly BRAHSH-no
• š sounds like English sh

So:

• brašno = BRAHSH-no
• ulje = OOL-ye

Yes, in natural English that can work, especially if you are just stating what appears on the list.

But grammatically, the Serbian sentence is built more like:

• Flour and oil are on the list

Serbian often uses simple to be sentences where English might choose either:

• X is/are on the list
• There is/are X on the list

So the Serbian structure here is straightforward:

• location phrase: Na spisku
• verb: su
• subject: brašno i ulje
