La bankejo sendis la konteltiron.

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

So:

• banko = a bank
• bankejo = a bank place, bank office, bank branch, or the bank premises

In everyday Esperanto, many speakers would simply say banko. Using bankejo puts a bit more focus on the place or office itself rather than the institution in the abstract.

So this sentence sounds a bit like the bank office/branch sent...

Sendis is the past tense of sendi = to send.

Esperanto verb endings are very regular:

• -as = present
  
  • sendas = sends / is sending
• -is = past
  
  • sendis = sent
• -os = future
  
  • sendos = will send

So sendis clearly shows that the action happened in the past.

The -n ending marks the direct object in Esperanto.

Here:

• La bankejo = the subject, the thing doing the action
• la konteltiron = the object, the thing being sent

So the sentence structure is:

• La bankejo = the bank branch
• sendis = sent
• la konteltiron = the account statement / account extract

The -n shows that konteltiro is what was sent.

Because it is the subject, not the direct object.

In Esperanto, the direct object gets -n, but the subject normally does not.

So:

• La bankejo sendis... = the bank branch sent...
• La konteltiron... = the item that was sent

This is one of the most important uses of -n in Esperanto.

It is a compound word:

• konto = account
• eltiro = extraction, extract, withdrawal, pulling out

So konteltiro literally means something like account extract, which corresponds to account statement or statement extract in English, depending on context.

Esperanto often builds words this way by combining roots directly.

This is normal in Esperanto compounds.

When one root comes before another, the final grammatical ending is often removed:

• konto → kont-
• eltiro stays as the main part of the word

So:

• konto + eltiro → konteltiro

This is similar to how Esperanto builds many compound words. The last part is usually the main idea, and the earlier part modifies it.

La is the definite article, meaning the.

It is used before both nouns because both are definite:

• La bankejo = the bank branch
• la konteltiron = the account statement

Unlike English, Esperanto has only one article:

• la = the

There is no separate word for a/an. If you want an indefinite noun, you usually just leave out the article.

The normal word order is subject + verb + object, and that is what we see here:

• La bankejo = subject
• sendis = verb
• la konteltiron = object

But Esperanto word order is more flexible than English because the -n ending shows the object.

For example, this would still mean the same thing:

• La konteltiron sendis la bankejo.

That said, the original order is the most neutral and natural for learners.

Potentially, yes, depending on context, because eltiro can relate to drawing out or extracting.

However, if the meaning shown to the learner is account statement or account extract, then that is the intended meaning here.

In real usage, financial vocabulary can vary, and sometimes a more explicit form might be used to avoid ambiguity. But as a compound, konteltiro is understandable as something extracted from an account.

Not necessarily. Sendi simply means to send.

It could mean:

• mailed physically
• emailed
• transmitted electronically
• sent through an online banking system

The sentence itself does not specify the method. Only the fact of sending is expressed.

It is grammatically fine, but depending on style, some speakers might choose slightly different vocabulary.

For example, someone might prefer:

• banko instead of bankejo
• a different financial term instead of konteltiro

So the sentence is useful for learning Esperanto structure, especially:

• the use of la
• the past tense -is
• the direct object -n
• compound word formation

Even if another wording might be more common in some situations, the grammar here is very typical Esperanto.
