La petanto transdonas la peton al la konsulo.

The -n ending marks the direct object in Esperanto: the thing directly affected by the verb.

• La petanto = the applicant/requester → the subject, the person doing the action
• transdonas = hands over / delivers
• la peton = the request/application → the direct object, the thing being handed over
• al la konsulo = to the consul → the recipient

So peton gets -n because it is what is being handed over.

Konsulo does not get -n here because it comes after the preposition al (to). Prepositions already show the role of the noun, so you normally do not add -n after them.

Al means to.

In this sentence, it shows the recipient of the action:

• La petanto transdonas la peton al la konsulo.
• The applicant hands over the request to the consul.

A useful way to think about it:

• la peton = the thing being given/handed over
• al la konsulo = the person it is given to

Because la is the Esperanto word for the, and it does not change for gender, number, or case.

So:

• la petanto = the applicant
• la peton = the request
• la konsulo = the consul

Esperanto uses the same definite article everywhere: la.

Also, Esperanto has no indefinite article. So:

• petanto can mean an applicant or just applicant, depending on context
• la petanto means the applicant

-as is the present-tense verb ending in Esperanto.

So:

• transdoni = to hand over / to transfer
• transdonas = hands over / is handing over

Esperanto verb endings are very regular:

• -as = present
• -is = past
• -os = future
• -us = conditional
• -u = command / jussive
• -i = infinitive

So transdonas tells you the action is happening in the present.

Petanto is built from:

• pet- = ask for, request
• -ant- = present active participle
• -o = noun ending

So petanto literally means one who is asking/requesting.

In natural English, that may be translated as:

• applicant
• requester
• petitioner

depending on context.

This is a very common Esperanto pattern:

• lernanto = learner, student
• parolanto = speaker
• laboranto = worker

So petanto is a person characterized by the action of peti.

They come from the same root pet-, but they are different words with different endings.

• petanto = applicant / requester

  • a person
  • ends in -o because it is a noun
  • contains -ant-, which shows “someone doing the action”

• peton = request / application

  • a thing
  • basically peto
    • -n
  • -n marks it as the direct object

So in this sentence:

• petanto = the person making the request
• peton = the request itself

Yes, it is one word, and it is made very regularly:

• doni = to give
• trans- = across, over
• transdoni = to hand over, transfer, pass on
• transdonas = hands over / transfers

This kind of word-building is extremely common in Esperanto. Once you know the parts, many words become easy to understand.

Here, transdoni gives the idea of not just giving, but passing something onward to someone else.

Yes. Esperanto word order is fairly flexible because grammar endings show the roles of the words.

In the original sentence:

• La petanto transdonas la peton al la konsulo.

you could also say, for example:

• La peton la petanto transdonas al la konsulo.
• Al la konsulo la petanto transdonas la peton.

These still mean basically the same thing, because:

• peton has -n, so it is the direct object
• al la konsulo shows the recipient

That said, the most neutral and common order is still:

subject + verb + object + other phrases

So the original sentence is the most straightforward version.

Because Esperanto distinguishes between the direct object and other roles very clearly.

The direct object is marked with -n:

• la peton = the request

But the consul is not the direct object. The consul is the recipient, and that role is shown with the preposition al:

• al la konsulo = to the consul

So even though the consul is involved in the action, Esperanto does not treat it as the direct object here.

Grammatically, yes, you could say:

• Petanto transdonas peton al konsulo.

But the meaning becomes less specific, more like:

• An applicant hands over a request to a consul
• or Applicant hands over request to consul

In normal usage, whether you include la depends on whether the people/things are definite and already identifiable in context.

So the version with la sounds like we are talking about specific, known people/things:

• the applicant
• the request
• the consul

Because Esperanto usually uses a preposition instead, especially al for to.

English also often does something similar:

• I give the book to the teacher.

Esperanto prefers a clear structure:

• direct object → -n
• recipient/goal → often al

So:

• la peton = direct object
• al la konsulo = indirect object / recipient

This makes sentence structure very regular and easy to recognize.
