La poto staras sola ĉe la fenestro.

In Esperanto, stari means to stand or to be standing/upright. It is often used for things that are in an upright position, not just people.

So La poto staras... suggests that the pot is standing there upright, not merely that it exists.

• La poto estas ĉe la fenestro = The pot is at the window.
• La poto staras ĉe la fenestro = The pot is standing by the window.

The second version gives a clearer picture of position.

Yes. In Esperanto, verbs like stari, sidi, and kuŝi are commonly used for the position of objects as well as people.

A native English speaker may find this a little unusual, but it is very normal in Esperanto:

• stari = be standing, be upright
• sidi = be sitting, be placed in a sitting-like position
• kuŝi = be lying, be in a horizontal position

So a pot can absolutely stari if it is upright on a surface.

Sola is an adjective, and it describes la poto. It means alone or by itself.

So:

• La poto staras sola = The pot stands alone.

Here sola agrees with poto, which is singular, so it also stays singular.

If you used sole, that would be an adverb, meaning something more like only or solely, and that would not fit the same way here.

In Esperanto, predicate adjectives often come after the verb, just like in English:

• La poto estas sola = The pot is alone.
• La poto staras sola = The pot stands alone.

Here sola is not simply part of the noun phrase la poto. It is describing the state of the pot in the sentence.

Compare:

• la sola poto = the only/sole pot
• la poto staras sola = the pot stands alone

These do not mean the same thing.

This is an important distinction.

• la sola poto means the only pot or the one pot
• la poto staras sola means the pot stands alone

So:

• sola before the noun usually becomes part of the noun phrase
• sola after the verb describes the condition or state of the noun

In this sentence, the meaning is clearly that the pot is by itself, not that it is the only pot in existence or in the room.

Ĉe usually means at, by, with, or in the vicinity of, depending on context.

In ĉe la fenestro, it means something like:

• by the window
• at the window
• near the window

It does not necessarily mean the pot is touching the window. It just places it in that area.

Both could work, but they are slightly different.

• ĉe = at/by/in the area of
• apud = next to, beside

So ĉe la fenestro is a little broader and less exact. It means the pot is by the window area.

If you said apud la fenestro, that would emphasize that it is specifically beside the window.

Because fenestro is not the direct object here.

The structure is:

• La poto = subject
• staras = verb
• sola = predicate adjective
• ĉe la fenestro = prepositional phrase

In Esperanto, nouns after prepositions like ĉe normally do not take -n.

So:

• ĉe la fenestro = by the window

No accusative is needed.

La is the definite article, meaning the.

Esperanto uses the same article la for all nouns, regardless of gender, number, or case.

So:

• la poto = the pot
• la fenestro = the window

Unlike English, Esperanto has only one definite article form. There is no separate word for a/an, so if you wanted a pot, you would usually just say poto.

Staras is present tense.

In Esperanto:

• -as = present
• -is = past
• -os = future

So:

• staras = stands / is standing
• staris = stood / was standing
• staros = will stand / will be standing

Yes, Esperanto word order is fairly flexible, though some orders sound more natural than others.

The most neutral order here is:

• La poto staras sola ĉe la fenestro.

But you could also say:

• Sola staras la poto ĉe la fenestro.
• Ĉe la fenestro staras la poto sola.

These are grammatically possible, but they shift emphasis. For learners, the original order is the safest and most natural.

Poto means pot. Depending on context, it could be a pot, jar, or plant pot.

If you want to be more specific, Esperanto often uses compounds or more precise words. But in many contexts, poto is enough.

So in this sentence, the exact type of pot is probably understood from the situation rather than from the word alone.
