Lampa je nad stolom.

Serbian does not have articles like English a and the. So lampa can mean a lamp or the lamp, depending on context.

In Lampa je nad stolom, the noun lampa by itself is enough. If you want to know whether it means a lamp or the lamp, you usually figure that out from the situation or the wider conversation.

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

So:

• lampa = lamp
• je = is
• nad stolom = above the table / over the table

In a normal Serbian sentence like this, je is needed because it links the subject with the location.

Because sto changes form when it is used in different grammatical cases.

The basic dictionary form is sto (table), but after the preposition nad in a location meaning, Serbian uses the instrumental case, so sto becomes stolom.

A few forms are:

• sto = table
• stola = of the table
• stolu = to/on the table
• stolom = with/by/under/over the table, depending on the preposition

So in Lampa je nad stolom, stolom is instrumental singular.

The preposition nad often goes with the instrumental case when it describes a static location.

Here the lamp is simply located above the table, so:

• nad + instrumental = location above something

That is why you get nad stolom.

A useful pattern:

• Knjiga je pod stolom. = The book is under the table.
• Slika je nad krevetom. = The picture is above the bed.

Not always. With prepositions like nad, Serbian often makes a distinction between:

• location → instrumental
• movement toward a position → accusative

So:

• Lampa je nad stolom. = The lamp is above the table.
  (location, so instrumental)

Compare that with a motion idea such as placing something into a position above something else, where the accusative can appear.

For beginners, the safest rule is:

• if something is located above something, use nad + instrumental

Because lampa is the subject of the sentence, and subjects normally appear in the nominative case.

So here:

• lampa = nominative singular
• stolom = instrumental singular

Also, lampa is a feminine noun, but that does not force any visible change here because it is already in its basic form.

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

The neutral order here is:

• Lampa je nad stolom.

But other orders are possible, depending on emphasis, for example:

• Nad stolom je lampa. = Above the table is a lamp / The lamp is above the table.
• Je lampa nad stolom? = Is the lamp above the table?

Even though word order can move around, the clitic je has its own placement rules and usually appears near the beginning of the clause, not just anywhere.

They are similar, but not always identical.

• nad often means over / above
• iznad more clearly means above in a spatial sense

In many contexts, both are possible, but the structure changes:

• Lampa je nad stolom.
• Lampa je iznad stola.

Notice the difference:

• nad + instrumental → nad stolom
• iznad + genitive → iznad stola

Both can mean that the lamp is above the table, but learners should remember that the noun case changes with the preposition.

Because na stolu means on the table, not above the table.

Compare:

• Lampa je na stolu. = The lamp is on the table.
• Lampa je nad stolom. = The lamp is above the table.

So na expresses contact with the surface, while nad expresses a position higher than something.

You add nije, the negative form of je:

• Lampa nije nad stolom. = The lamp is not above the table.

This is a very common pattern:

• je = is
• nije = is not

In standard Serbian, the dictionary form is usually sto.

The noun has an oblique stem stol- in many other cases, which is why you see stolom here.

So:

• dictionary form: sto
• in this sentence: stolom

This is normal and is something learners simply have to get used to with a few Serbian nouns.

Yes, it is grammatical and understandable.

A very natural alternative is also:

• Lampa je iznad stola.

Many speakers may prefer that version in everyday speech, but Lampa je nad stolom is still a correct and useful sentence, especially for learning how nad works with the instrumental.
