La princo ricevis konteltiron ĉe la bankejo.

Esperanto has one article, la, which means the. It does not have a separate word for a/an.

So:

• la princo = the prince
• la bankejo = the bank building / the bank place
• konteltiron with no article can mean an account extract / a statement depending on context

A bare noun in Esperanto is often indefinite, where English would use a/an.

In Esperanto, all nouns end in -o.

So princo is a noun. The ending tells you its part of speech immediately.

A few related forms are:

• princo = prince
• princoj = princes
• princon = prince as a direct object
• princojn = princes as direct objects

In this sentence, princo is the subject, so it stays princo, not princon.

The ending -is marks the past tense in Esperanto.

So:

• ricevi = to receive
• ricevas = receives / is receiving
• ricevis = received
• ricevos = will receive

A very helpful feature of Esperanto is that verbs do not change for person or number. The same form is used with I, you, he, she, we, they, etc.

So:

• mi ricevis
• li ricevis
• ili ricevis

all use the same past-tense verb form.

The ending -n marks the direct object.

Here, the thing that was received is konteltiron, so it gets -n.

Compare:

• La princo ricevis konteltiron. = The prince received the account extract.
• La konteltiro ricevis la princon. would mean the account extract received the prince, which is obviously a very different meaning

This -n ending is one of the most important features of Esperanto grammar, because it clearly shows what is being acted on.

Yes. It is a compound noun.

Esperanto often builds longer words by combining roots. In a compound, you usually use the root, not the full dictionary form with -o.

So this word is built from something like:

• kont- = account-related root
• eltir- = extract / withdrawal / pulling out
• -o = noun ending

That gives konteltiro.

English does this too with words like bank statement, account holder, or bookstore. Esperanto just does it in a very regular way.

ĉe usually means at, by, or with, depending on context.

In this sentence, it means something like at the bank.

It often indicates a location associated with a person or place, without focusing on being physically inside it.

For example:

• ĉe la banko = at the bank
• ĉe la kuracisto = at the doctor's
• ĉe mia amiko = at my friend's place

So ĉe is often the natural choice for service locations and institutions.

Both ĉe and en can refer to location, but they are not exactly the same.

• ĉe = at the bank, in a general or situational sense
• en = in/inside the bank, emphasizing the interior

So ĉe la bankejo sounds like the normal English idea of at the bank, while en la bankejo would stress physical inside-ness more directly.

An English comparison would be:

• I got it at the bank = general location
• I got it in the bank building = more physically specific

The suffix -ej- means place for or place associated with something.

So:

• lerni = to learn
  lernejo = school, a place for learning
• manĝi = to eat
  manĝejo = dining room, eating place
• bankejo = bank premises / bank place / bank branch

In other words, bankejo emphasizes the physical place where banking happens.

Banko is often enough in normal Esperanto, just like bank in English can mean both the institution and the building.

Bankejo makes the idea of a physical location more explicit. It is very transparent and understandable because of -ej-, even if many speakers might simply say banko in everyday use.

So the difference is roughly:

• banko = bank, often the institution, and sometimes also the place
• bankejo = the bank building, branch, or premises

Because bankejo is part of a prepositional phrase: ĉe la bankejo.

The -n ending is mainly used for:

1. the direct object
2. sometimes direction in certain expressions

Here, bankejo is neither the direct object nor a direction word. It is simply the place where the action happened, introduced by ĉe.

So:

• konteltiron gets -n because it is the object
• bankejo does not get -n because it is the location after a preposition

Yes. Esperanto word order is fairly flexible.

The sentence as given is the most neutral, straightforward order:

• La princo ricevis konteltiron ĉe la bankejo.

But you could also say, for example:

• Ĉe la bankejo la princo ricevis konteltiron.

That shifts the emphasis a bit toward the location.

Because konteltiron has the object marker -n, its role remains clear even if the order changes. That is one reason Esperanto allows more freedom than English.

A couple of useful pronunciation points:

• ĉ sounds like English ch in church
• c sounds like ts
• stress in Esperanto almost always falls on the second-to-last syllable

So:

• ĉe sounds roughly like cheh
• princo sounds roughly like PRINT-so
• ricevis sounds roughly like ree-TSEH-vis
• bankejo sounds roughly like ban-KEH-yo

That regular spelling-and-sound system is one of Esperanto's easiest features once you get used to it.
