La kamerao kun la objektivo restas sur la tripiedo.

Because Esperanto uses la for the, and each definite noun phrase normally gets its own article.

So here:

• la kamerao = the camera
• la objektivo = the lens
• la tripiedo = the tripod

English sometimes feels looser about repeating the, but in Esperanto it is very normal here.

Also, if the lens were not a specific one, you could say kun objektivo = with a lens.

Restas means remains, stays, or keeps being in that place/state.

So:

• estas sur la tripiedo = is on the tripod
• restas sur la tripiedo = remains/stays on the tripod

Using restas adds the idea that the camera continues to be there, instead of simply stating its location.

In Esperanto, all present-tense verbs end in -as.

So:

• resti = to remain
• restas = remains / is remaining / stays

This ending does not change for different subjects:

• mi restas = I remain
• vi restas = you remain
• la kamerao restas = the camera remains

That is much simpler than English verb conjugation.

Because there is no direct object.

The sentence has:

• a subject: La kamerao kun la objektivo
• a verb: restas
• a prepositional phrase: sur la tripiedo

In Esperanto, the accusative -n is mainly used for direct objects, and sometimes for motion toward something. Neither applies here.

Compare:

• La kamerao restas sur la tripiedo. = The camera remains on the tripod.
• Mi metas la kameraon sur la tripiedon. = I put the camera onto the tripod.

In that second sentence, la kameraon is a direct object, and tripiedon can take -n because of motion onto something.

Most naturally, it describes the camera: the camera with the lens.

So the structure is basically:

• La kamerao kun la objektivo = the camera with the lens
• restas sur la tripiedo = remains on the tripod

In context, a phrase with kun can sometimes feel slightly ambiguous, but here the most natural reading is that the lens belongs with or is attached to the camera.

If you wanted to make that relationship even clearer, context usually does the job, but you could also rephrase.

Sur means on, usually in the sense of being on a surface or supported by it.

So:

• sur la tripiedo = on the tripod

This is the normal preposition for physical placement on top of something.

Some useful comparisons:

• sur = on
• en = in
• sub = under
• apud = beside

Not always. Many learners will more often see fotilo for a camera, especially a photographic camera.

So:

• fotilo = camera
• kamerao = a more international-looking form, but less often the everyday choice in many contexts

That means this sentence is understandable, but La fotilo kun la objektivo restas sur la tripiedo may sound more familiar to many Esperanto speakers.

It is a compound word:

• tri = three
• pied = foot
• -o = noun ending

So tripiedo literally means three-foot or three-legged support, which matches the idea of a tripod.

Esperanto uses compounds like this very naturally, and they are often quite transparent once you know the parts.

Yes. Esperanto word order is fairly flexible because the grammar is marked in other ways.

This sentence uses a neutral order:

• La kamerao kun la objektivo restas sur la tripiedo.

But you could also say:

• Sur la tripiedo restas la kamerao kun la objektivo.

That version puts more focus on sur la tripiedo.

Even so, the original order is probably the most straightforward and natural for a learner.

Esperanto pronunciation is very regular.

• kamerao is pronounced in four syllables: ka-me-ra-o
• tripiedo is pronounced tri-pi-e-do

A few key points:

• Every vowel is pronounced.
• The stress is on the second-to-last syllable.
• So you get:
  • kameRAo
  • tripiEdo

That may feel unusual to an English speaker, especially where two vowels come together, but Esperanto normally keeps them separate rather than blending them heavily.
